2 species of cetaceans and hundreds of pelagic birds, but way too many balloons
A great way to start our 30th season with 75-100 Tamanend's bottlenose dolphins, a finback whale, and lots of pelagic birds. Today's trip was a nice way to beat the heat and see wildlife. Our first encounters were with several groups of Tamanend's bottlenose dolphins (Tursiops erebennus), as many as 5-6 groups totaling 75-100 individuals, including some moms and calves in the near shore waters west of Montauk. There were also a few Great shearwaters (Ardenna gravis) and Cory’s Shearwaters (Calonectris borealis). We eventually decided to head southward (offshore). Things were quiet, with a few shearwaters and storms petrels, as we traveled, we reached an area where the ocean became alive with birds, bait, and ultimately a baleen whale. We were in 170’ of water, with prey from the bottom to the surface. We knew we were in the right spot and eventually saw the characteristic 20-foot blow of a finback whale (Balaenoptera physalus). What a pleasure it was to find this majestic, fast, and sleek individual. Finback whales are the 2nd largest animal. We watched it for about 30 minutes before making our way back to the dock. This was our 110th consecutive trip (since 2019) finding cetaceans. While we never guarantee it, we do our best to find them and have been doing it longer than any other group in the NY Bight.
Totals:
Unfortunately, just about every direction we looked, we saw balloons on the surface of the water. We scooped up as many as we could but didn’t have the time to grab more. The ones we removed were graduation celebratory balloons. Come on folks – stop buying and releasing balloons, they are killers.

Our 3rd trip of the 2025 season was the 1st time in a while that we didn’t find a baleen whale. It was a great trip nonetheless! The earlier rain/drizzle and dense fog gave way to incredible unlimited visibility. We were all ready to encounter cetaceans (whales, dolphins, and porpoises), as well as pelagic birds. We had reports, but had a planned route to head to where we’d seen that finback whale one 6/29 and 6/30.
As we headed out, we encountered a small pod of about 20 Tamanend’s bottlenose dolphins, along with a few Great Shearwaters and Cory’s Shearwaters. In a short while, we encountered another group of about 50-75 Tamanend’s bottlenose dolphins, as well as more shearwaters, and Wilson’s Storm Petrels. The area offshore where days before we found the whale and loads of bait fish throughout the water column (surface to 170 feet) not productive. We headed closer to shore and ultimately came across a massive aggregation of Tamanend’s bottlenose dolphins. We watched as several pods joined together repeatedly top interact and feed. Captain Dave Marmeno told us that the bait profile on the sonar was indicative of squid, and lots of it. These dolphins were spending a lot of time beneath the surface, most likely feeding on those deep squid.We saw moms and calves, adults, juveniles. It was a pleasure to watch. Eventually we had to head back to the dock and a few saw a seal just of Gin Beach.

Happy Independence Day! For our fourth trip on the Fourth (say that five times fast!), we set sail under sunny skies and excellent sea conditions. Our first cetacean encounter occurred quickly with a small pod of Tamanend’s bottlenose dolphins as we steamed passed the lighthouse. We spent some time observing this group of approximately a dozen dolphins before continuing in search of other species. We headed towards an area where humpback whales were seen a day prior, not far from where also observed a fin whale on previous trips. Despite near unlimited visibility and calm seas, no baleen whales were found. Instead, we enjoyed nice views of Cory’s and great shearwaters along with sporadic sightings of Wilson’s storm petrels. We also stopped a few times to pick-up multiple batches of mylar balloons which otherwise kill marine life (especially sea turtles) when ingested. About six miles off Napeague, we encountered another pod of Tamanend’s bottlenose dolphins. This aggregation was larger than the first with multiple small pods and one large pod of 40-60 individuals surrounding the vessel affording everyone outstanding views. Some of the dolphins were tail-slapping, a form of non-vocal communication which could also serve as a hunting mechanism to stun prey. With little bait detected, however, these displays were most likely interactive. We stayed in neutral as the dolphins surrounded the vessel, when suddenly a group of at least 12-16 simultaneously surged to the surface to the delight of those of us onboard. Other synchronized leaps followed before we continued north and east towards Montauk. Another small group of Tamanend’s was observed on our return. What a great way to celebrate the Fourth of July!

We found our first humpbacks (and common dolphins) of the season!
Yesterday was a beautiful day to be out on the water and sightings began early with a gray seal in the harbor upon departure. We first headed south to an area where whales were reported to be the day prior, but despite significant bait detected beneath the surface, no whales were found. Sporadic sightings of Cory’s and great shearwaters kept us entertained while we continued east in our search towards a second area where whales were also reported, but at first, it seemed as if the whales had moved away. Then, a blow! Upon investigation, it was found to belong to MTK119 (also known as Loon in the Gulf of Maine catalog*), a humpback whale previously documented by CRESLI off Montauk in 2022 and 2023. We spent some time alongside this whale before investigating two other blows about a quarter mile away. As we did, a pod of short-beaked common dolphin charged toward our vessel to the sheer delight of those onboard. Surrounded by dolphins, we now had views of the second humpback, MTK141 (known as Celebration in the Gulf of Maine catalog*), who was previously seen off Montauk in 2023 and 2024, making this the third consecutive year we observed this humpback in our waters. In fact, MTK141 is quite familiar to CRESLI having been sighted eleven times over three months in 2024! There were two other humpbacks in the area, but the whales were diving for about six minutes at a time and not feeding cooperatively so it was difficult to reach the other two while observing the ones closest to us. Viking and CRESLI are proud participants of WhaleSENSE, a voluntary program promoting responsible and ethical whale watching and we do not transit with whales below until we know they are safely away from the vessel. We used this time wisely though, removing a mylar balloon, from the water. Common dolphins continued to approach the vessel as we eyed a navy combat ship, the USS Billings (as later determined by the hull number) in the distance. It was a very exciting and awe-inspiring day on the water and we cannot wait to get back out! Please note that as members of the Whale SENSE system, we are committed to responsible whale watching and will always abide by the constraints of the Marine Mammal Protection Act and never harass, chase, or disturb them.

Our 1st 3 species day of the season!!
We left the dock ready to look for the humpback whales sighted the day before (7/6/25). We new it would take a while to get out to the zone and began looking esly and found a small pod of about 10 Tamanend’s bottlenose dolphins. They were nice to view, but very elusive and we continued our way. We found a humpback whale with a highly curved dorsal fin. It was making shallow dives and rarely putting it’s flukes. Actually, it was logging most of the time, that is, essentially sleeping just at or below the surface. Occasionally fluking and diving deep and staying down for 5-7 minutes ((the prey was 150’ down). The time spent with this whale travelling ENE and surfacing to blow every 30 seconds while sleeping, was well worth it. Of course, we were joined out there by a pod of short-beaked common dolphins. These dolphins swam towards us, with and around us for a while as we remained out of gear.
We also encountered the typical array of pelagic birds and picked up more balloons.
This was a great trip and we are trying to ID this humpback whale . Check back with us in a few days.

On yesterday’s trip, we followed-up on some reports of whale and dolphin activity to our south. We headed out under beautiful weather conditions, exchanging cool ocean breezes for the steamy conditions left behind on land. About two miles out, we had our first cetacean encounter with a group of Tamanend’s bottlenose dolphin. What was first believed to be a small group of a dozen or so ended up being 30-40 individuals swimming around the vessel. Everyone got great looks at the pod(s) before steaming our way south. Eventually we got into an area that was ripe with bird activity; Cory’s and great shearwaters, along with common tern were numerous, and bait was detected from 40-50 ft to the surface. This was a good area for whales, but none were yet found. So we traveled east until a large splash was detected, belonging to a kick-feeding humpback whale. This was the first of five humpbacks encountered in a thick sea of sand eels. Scores of shearwaters joined in on the feast and we enjoyed spending time on the water as whales surrounded the vessel feeding and diving on the bounty. As we left, a small pod of dolphins appeared next to the vessel to the delight of those watching from the bow. It was wonderful being in the presence of such active whales again.
Viking and CRESLI are proud members of NOAA’s Whale SENSE program promoting responsible and ethical whale watching. We do not chase or crowd the whales and keep a safe distance while observing them. Every trip is different and we never know what we will see or experience. Book your first or repeat trip with us today!

Wow, what a day we had on the water yesterday!
Numerous reports of whales in the area had us excitedly heading out in search of some of the humpbacks we had seen on Wednesday’s trip. But to our surprise, our transit was ‘interrupted’ by the sightings of three finback whales less than halfway to our destination. The massive whales were feeding on sand eels, with one seen lunge-feeding on its side at the surface. Fin whales are extremely fast and can travel tremendous distances in a short time, so we enjoyed watching them for a bit, before they – and we – traveled on. About twelve miles offshore, we found blows belonging to two, and then four, and then five humpback whales. All types of feeding and surface displays were observed with one humpback kick-feeding at the surface, another open-mouth feeding with excellent views of its baleen, and another breaching beyond our vessel. We spent time with these whales, while more blows were observed in the distance, and we traveled on to investigate. Again, to our surprise, two fin whales appeared in the mix, along with a minke whale, while tails of humpbacks dove in the distance. What an amazing experience! We reached the additional humpbacks and were pleased to see the tails belonged to a mom/calf pair that had been encountered on Wednesday’s trip. Humpbacks often form associated pairs while feeding and can vary in size and length, so we are always cautious to identify a pair as mom/calf without additional observation. This sighting confirmed what we believed on Wednesday to be our first humpback mom and calf pair of our 2025 season. What a wonderful way to spend a summer’s day on the water.

Oh, what a trip we had- 5 species of cetaceans!!
Our 2025 season is getting better and better. Today’s trip initially brought us to a small group of ~20 Tamanend’s bottlenose dolphins. Quickly we began to find more groups, , and ultimately a massive aggregation of 300 individuals. We stayed with them for a while and then headed further offshore and found a zone with finback whales and their characteristic 20’ tall inverted coned-shaped blows. The water column was loaded with sand eels and the surface loaded with pelagic birds. We were able to get ID photos from about 6-8 finbacks, although we could see blows in every direction for a few miles. After a while we decided to check out the humpbacks in the same area. Sea-nettle, Mostaza, and a few others to be ID’d were there. Sea-nettle regularly kick-feeding, the others sometimes bubble mist feeding, and occasionally open-mouth feeding. Throughout this area we occasionally saw several minkes whales as well.

This was a tremendous and memorable trip! We started out toward an area with heavy bait and numerous reports of cetacean activity. En route, we encountered a juvenile humpback whale that was spending brief intervals at the surface, just enough to give everyone a quick look, before we decided to move on. Within a few miles, we saw numerous spouts ahead of us, the first belonging to a finback (fin) whale, the second largest animal on Earth. While observing this endangered species, a minke whale popped up near the vessel, followed by a second blow belonging to the tiniest of minke whales, about one third the size of the adults we typically see. From there, we spent time with a group of 60-100 short-beaked common dolphins which approached our vessel and swam all around us affording everyone onboard incredible views, as well as a second fin whale in the area. Then, it was time to meet our second humpback of the day, a tail-throwing individual exhibiting long dive times (likely feeding on the incredible density of bait detected beneath us) so we continued toward a third humpback observed bubble cloud feeding ahead of us. This whale continuously produced bubble clouds (about every two minutes) around our vessel, confusing and trapping the sand eels that are in abundance here. A minke whale was seen here as well, completing an exciting spectacle of wildlife just eight miles off Montauk. A small group of Tamanend’s bottlenose dolphins were spotted on our return transit, wrapping up an incredible five-species cetacean day.
We never know what we will see, but it seems like this season is heating up, and these trips are truly a dream come true. Come on out with us and experience this splendor for yourself!

A spectacular afternoon with an interesting and well-known humpback whale and loads of dolphins! On a brutally warm and muggy day on land, we were already for a cooler day at sea. We headed towards the area where we’d been seeing dense patches of prey, birds, and cetaceans for the past week. The prey, and predators (cetaceans and birds) were gone. We had to pick a direction to travel, westward or eastward. We started heading west, but Captain Dave Marmeno changed his mind and turned us eastward. That was the right move. We spent time with a large aggregation of short-beaked common dolphins. Thern we saw blows from far off and found 25-year-old Mostaza, a female humpback whale that we’d seen on our past 2 trips (and many times before). Mostaza was open-mouth feeding, each time after she closed her mouth, she would roll-over. The dolphins came over as well. This was a magical encounter that included lots of pelagic birds as well.

It was a beautiful day on the water yesterday with a refreshing breeze and cooler temperatures than those experienced earlier in the week. The whales were around and we found our first – a humpback about seven miles off Montauk. This whale was spending long intervals beneath the surface and popping up only briefly 200-300 yards away, making for a difficult encounter. We decided to continue in hopes of finding another individual, which we did, just ahead of the first. This whale, however, was also exhibiting long dive times and surfacing far away from the vessel and after photographic investigation post-trip, turned out to be the same individual as previously encountered. With little bait detected in the area, it is likely this whale was traveling (and quickly at that) in search of food. While quite natural an observation, we realize this can be frustrating for passengers who want a closer look, so we continued on in search of others. About 15 miles off Montauk, we observed two blows, belonging to a presumed-juvenile humpback and a small finback whale. Both whales were exhibiting the same behavior as the first two, with long dive times and distance traveled between blows. With little bait detected here as well, we understood that they were also on the move, so we decided to do the same by heading west toward an area where we have encountered cetaceans previously. Here, we found between 80-100 short-beaked common dolphins who were more than happy to delight everyone on board by approaching the vessel and swimming alongside for minutes at a time, offering everyone incredible views and a truly memorable encounter. On one of their approaches, passengers could hear the dolphins communicating underwater – an amazing experience! Birders on board were happy to document three species of shearwater and a good number of Wilson’s storm petrels. The return trip along the south shore offered everyone outstanding views of Montauk’s cliffs and beaches, and its historic lighthouse and grounds.

It was absolute cetacean heaven at sea yesterday!
We headed offshore, pausing only briefly to investigate some nearshore splashes and visible leaps, likely belonging to tuna and/or other large, predatory fish. Our transit was speckled with pelagic bird sightings, at times by the hundreds, before we encountered our first whale, a somewhat elusive humpback with long dive times and distant surfaces. While waiting, we were treated to a splendor of hundreds of short-beaked common dolphins charging towards and swam alongside the vessel, giving everyone amazing and incredible views. The very acrobatic and energetic dolphins included adults and juveniles, and the tiniest of calves which appeared, with mom, adjacent to our ship as if to show her newborn off. This made the wait between blows very easy to tolerate. We eventually gained better views of the whale, which at one point was flanked by dozens of dolphins, some of which were bow-riding the humpback! Beyond this magical spectacle, a large blow belonging to a fin whale appeared just as a minke whale sliced through the surface. In one line of sight, we had FOUR CETACEAN SPECIES, a spellbinding experience for even the most seasoned passengers (and naturalist/volunteers)! We eventually moved toward the fin whale to discover at least two additional (fin whale) blows and a second humpback. As before, this humpback was surrounded by dolphins and many others were observed charging and porpoising in the distance. The sea was ‘boiling’ with dolphins and the sky was saturated with blows, just as another minke whale popped up within view. Seabirds were everywhere and soon the fin whales came easily into view with additional blows beyond. The only downside to this whale watch was that it had to end! While we didn’t want to leave, we were comforted by the warm summer sun and the afterglow of our extraordinary time at sea as we returned to port.
Every trip is different and we never know what we are going to see. Book your first or tenth adventure with us today!

What better way to celebrate World Whale and Dolphin Day than aboard another magical Viking/CRESLI whale watch! Our transit yesterday brought us southeast towards an area we dubbed “cetacean heaven” on Sunday’s trip. At first, it appeared as if the bait and the whales/dolphins had moved on with zero bird activity and no sign of life near the surface. That changed as we reached an area markedly noisier than before. Here, hundreds of great shearwaters and terns patrolled the area and we encountered our first pod of short-beaked common dolphin. The dolphins were acrobatic and inquisitive, swimming around our vessel with repeated close approaches to the delight of those onboard. Shortly after, a series of blows were observed and investigated, while repeated large splashing events occurred just beyond them. The blows belonged to at least one finback whale, while a lobtailing humpback was the source of all the splatter. The lobtailing continued with occasional tail-throws, presumably to communicate with other humpbacks in the area. This humpback then began feeding near the surface, popping up adjacent to dozens of dolphins and shearwaters, and then right next to a feeding finback whale! Everyone had great views of the action and additional blows were seen in the distance. The lobtailing seemed to work because another humpback moved in and we later investigated blows from a third humpback, which began bubble cloud feeding not far from our vessel. Sitting safely out of gear, we watched as blue water turned green reflecting its rich productivity contrasted against the bubbles produced by the feeding humpback. This humpback would then cut through the surface with its mouth (and soon belly) full of prey, as it strained out the water through hundreds of plates of baleen. Eventually, it was time to return home and transform these amazing experiences into lasting memories.

A challenging but successful day!
We left the dock expecting to escape from the heat and we did. We encountered wind and expected 4-5' seas. We found a pod of about 20-30 Tamanend's bottlenose dolphins about 1.5 nautical miles (nm) from Montauk Point. We then headed ESE, experiencing the classic "old-time rock-and- roll" of 4-5' seas for a few hours. We traveled through the area in which we'd found whales, dolphins, and pelagic birds on Monday 7/23/25. Spotting blows at distance was challenging due to all the white caps, and the wind, and waves. We searched and traveled and then at about 20 nm out, a finback whale blew 100 yards ahead of us! We could see the blows (3 or 4 a few seconds apart, and the whale would go down for a terminal dive of 5-10 minutes, then come up 100-200 yards away. After about 30 minutes, the whale briefly surface close enough to see and attempt to photograph its right side and dorsal fin. We will compare this fin whale to the other 201 fin whales in our catalog. It was a long and challenging trip. We got back to the dock and off the vessel just as a massive thunderstorm began. Perfect timing. We head out again on Sunday

This trip was punctuated with sightings from the start, and not limited to cetaceans. Our first-of-the-season sighting of bunker (Atlantic menhaden), an extremely important prey fish for a myriad of marine predators, kicked off our departure past the lighthouse. And not surprisingly, shortly thereafter, we encountered a large pod of Tamanend’s bottlenose dolphin. The pod was separated into two distinct groups, each consisting of tightly-packed individuals including adults, juveniles, and a few neonates (newborns) diving and surfacing together, with occasional tail slaps on the surface. While the sighting was invigorating, we decided to use our time wisely and continue east where baleen whales were seen on previous trips. As we transited, the sea boiled almost continuously with bait fish and occasional tuna, before the largest thing of all broke the surface behind us: a submarine! A possible spinner shark spiraled above the water while great and Cory’s shearwater and Wilson’s storm petrel sightings persisted. Our search brought us east of Block Island before returning northwest when numerous blows, belonging to at least six humpback whales, were excitedly investigated. While waiting for the whales to resurface, Bombay, a female who spent nearly the entire summer off Montauk with a calf last season breached immediately ahead of our vessel. Then the magic continued with whales popping up alongside the vessel and one particularly memorable close approach by Mostaza, the 25-year old daughter of Salt. Even more exciting? Our second mom/calf pair of the season was confirmed when Pickle, a whale encountered off Montauk three other seasons, was seen swimming closely with a calf. We saw Pickle eight times over 53 days in 2024, so knowing now that she was pregnant – and returning now as a nursing mother - speaks volumes of the nourishment this area can provide to this species. The enchantment culminated in a rare and beautiful approach by the quintet alongside our vessel, resting and breathing at the surface, affording everyone incredible views (and sounds) and ultimately wrapping up another tremendous day on the water.

Another challenging yet successful trip with whales and dolphins.
We headed out again to ostensibly cool off while looking for marine mammals. The relatively cooler water helped to curtain some of the brutal conditions and made things more comfortable than on land. We had multiple reports of whales to the south and decided mot head that way. As we traveled, we found a few pelagic birds and the numbers increased moderately, Cory's shearwaters, then great shearwaters, and Wilson's storm petrels. Eventually, we saw a humpback whale dive about 350 yards ahead of us. This was a large individual, but the prey was in the upper 1/3 of the water column so the whale undertook a shallow, non-fiuking dive. We waited for the whale to resurface, but in the haze we must have missed it and after 15 minutes headed on. Our next sighting was of a massive finback whale (~75') long. After a series of blows, it dove and we waited… 15 minutes and we must have missed this one also. The water had tremendous quantities of squid (one of the prey of fin whales). We headed on, and eventually 15 minutes later and 1.3 miles from where we'd first seen the whale, it surface again swimming rapidly to the east.

With the sun shining, a light, cool breeze, and nearly unlimited visibility, it was a perfect summer’s day for a whale watch. Under ideal sea and atmospheric conditions, we had our first signs of cetacean life, the tell-tale signs of a distant blow, approximately an hour after passing the lighthouse. We expertly followed the spout and waited for the whale, a mature finback, to surface. Typically, with fin whales, their speed, and long breath-holding times keep us a good distance away, but yesterday’s trip was an exception. This whale would surface, at first about 100-150 yards from our vessel, increasingly getting closer as we waited safely out of gear. Close approaches by fin whales are rare, but passengers got exceptional views as this whale, likely feeding on the dense patches of bait near the surface, appeared repeatedly around the vessel. To add to the excitement, two minke whales also popped up in close view, and like the fin whales, were uncharacteristically easy to watch. The minkes would appear predictably in an expected path of movement, making for repeated sightings between surface appearances by the finback. Off in the distance, two additional blows were seen and they, too, were moving closer toward us. These were two additional fin whales, believed to be a mom-calf pair due to size and behavioral characteristics, and excellent views were afforded of them as well. Then, a successful marriage proposal resulted in an eruption of applause amongst the passengers, and an air of joy surrounded us at sea. Additional blows, likely belonging to even more fin whales, were observed way out in the distance, too far for us to safely investigate while waiting on the fin whales to surface around us. Eventually, the dive times and distances of the whales increased, and we investigated a fourth fin whale with an interestingly faint blow (likely due to its small size) before heading back to port. Photos of these whales will soon be examined and Dr. Artie Kopelman, Senior Naturalist and Curator of the CRESLI Finback Whale Catalog, will determine whether these individuals have previously been documented in the area. Check out CRESLI’s SmugMug photo collection in a few days to follow-up (https://drartiek-cresli.smugmug.com/CRESLI-2025-Whale-Watches). And CONGRATULATIONS to the newly-engaged couple on board!

Awe Inspiring!
What an amazing trip! We headed to an area where whales used to be incredible prevalent for many years, and where whale had been the day before as well as the past weeks. It took a while to get there, and on a day with unlimited visibility, we began seeing whales from several miles away. Humpback whales, finback whales, and short-beaked common dolphins were around us, next to us, under us for several hours. Our senior scientist/naturalist, Dr. Artie Kopelman, is finished going through almost 1440 high resolution photos for good views of feeding and other behaviors, as well as photoidentification. We has open-mouth feeding and bubble feeding humpback whales. We saw whales in every direction but couldn’t get to all of them. Occasionally, when finm whales encountered short-beaked common dolphins, the fin whales blew bubble to keep the dolphin away! We sail Sunday, Mondays, Wednesdays and Fridays, and will begin adding Saturdays soon.

What a wildlife spectacle we witnessed off Montauk yesterday!
We always tell passengers how each trip is different and every outing brings with it a special uniqueness, but yesterday’s trip was both familiar and outstanding. Familiar in the sense that we’ve had days at sea like this before, yet exceptional and above and beyond what we ever hope to experience. The trip began with a small pod of Tamanend’s bottlenose dolphins, not far from the lighthouse. As we watched, multiple small pods joined together, first into a group of about twenty, before gaining more individuals into what ultimately became a pod of at least 120 dolphins. It was beautiful to watch their synchronicity and to witness how responsible whale watching pays dividends to all involved; it was as if the dolphins returned their respect for keeping our distance and passively observing by swimming and surfacing together alongside the vessel for much of our encounter. We eventually headed east and after about an hour of transit, we saw our first blow. Then another, and another, and another, and another, and so on, like the Bellagio fountains at Vegas! At first, the blows belonged to at least 6-8 fin whales, including a mom and calf pair. Four of the whales were surfacing and moving together, likely feeding on dense patches of sand eels about fifty feet beneath the surface. But then splashes in the distance caught our eye and eventually after moving safely away from the fins, we encountered the first of 8-12 humpback whales. These whales demonstrated nearly every surface activity possible: bubble, kick-, and open mouth feeding, flipper slapping, spy hopping, and partial and full breaches! The group consisted of at least two mom/calf pairs, one of which we encountered earlier this season (Pickle and her 2025 calf). As the surface behaviors ensued, fin whales remained in the area and one humpback breached right next to them! Then the dolphins arrived; these were the fast and acrobatic short-beaked common dolphins, who charged towards the bait as well as our vessel, giving everyone excellent and memorable views. Some passengers at the bow heard their vocalizations as well! It was chaotic in the most beautiful sense: fin whales to the left, humpbacks to the right (and left), dolphins at the bow, and then as you finally fix your gaze, a breach to interrupt whatever it was you decided to focus on. The breaches were numerous and exhilarating, and not to be ‘outdone’, a minke whale surprised us all at the bow with a close approach on both sides giving everyone great views of four cetacean species at once. It was a five cetacean species day and we returned full of happy memories and humbled by the grandeur of our special time at sea.

A long and exceptional day
We traveled to where many whales had been seen on the previous trip, only to find few pelagic birds, little bait, and 1 humpback whale that was repeatedly diving without fluking, for extended periods of time. About several long bouts waiting for this large whale to fluke, we headed on towards the previous days coordinates. We saw no whales and continued to head eastward. We were about 20 nautical miles (nm) east and decided to turn north before heading west. On our way back, we had encounters with 4 humpback whales (i.e., 2 associated pairs), approximately 2 miles north of where we'd looked for them. We were then joined by about 40 short-beaked common dolphins.
Unfortunately a computer malfunction has temporarily disturbed the typical photo review of the 8/8/25 trip until later |
Another exceptional trip for Viking/CRESLI is in the books!
With sunny skies, a refreshing breeze, and incredible visibility, it was already a great trip when we encountered a small pod of Tamanend’s bottlenose dolphins close to shore. We spent some time with them, but wanted to move on with reports of humpbacks to our south. After spotting a couple of blows and seeing flukes (of diving whales) at the surface, we knew we found at least two humpbacks, but the surprise was on us as they suddenly appeared at the surface open-mouth feeding on the rich bait detected below. These whales were bubble-net feeding, a coordinated effort where a circular (spiral) ring of bubbles is created to confuse and corral small schooling fish such as sand eels, and they were doing it again and again, all around us as the boat sat safely out of gear to watch. A third humpback was bubble cloud feeding (blowing a single burst or trail of bubbles individually), but at one point, joined in with the associated pair such that all three humpbacks could at once be seen feeding and then dragging (moving slowly along the surface straining out the water through their baleen to capture their prey). This went on for a while with bubbles – and then whales – appearing close to our vessel affording everyone exceptional views. Three finback whales were also in the area but despite being the second largest animal in the world and a rare and endangered species, most eyes were on the humpbacks, a testament to how incredible an experience it was to witness. A very small pod of short-beaked common dolphins was also briefly seen feeding near the surface. Eventually, it was time to return, but the incredible encounter kept everyone delighted even as we steamed home. Every trip is different and we never know what we will observe and witness. Come join us on our next adventure of discovery!

MONDAY AUGUST 11, 2025 OFFSHORE TRIP TO THE GREAT SOUTH CHANNEL (GSC) -
Perseid meteors, whales, dolphins, basking shark and more!
We left Sunday evening to begin our 36 hour trip to the Great South Channel. With enough bunks for 40 people below deck, many decide to sleep out under the stars and meteors. Morning brought us an exquisite sunrise. We had reports of where some whales had been seen by our colleague, Dr. Jooke Robbins, Director of the Humpback Whale Studies Program at Center for Coatsal Studies (https://coastalstudies.org/). This was our 26th offshore multiday trip, and the 25th to the GSC. Interestingly, most of our trips involved starting at almost exactly where Dr. Robbins suggested. The trip was phenomenal, with 30 or more humpback whales, as well as a basking shark. Dr. Artie Kopelman, CRESLI's president and senior naturalist had his hands full - almost 2800 high resolution photos are being reviewed. So far, half have been carefully vetted and he has identified 27 different humpback whales - more to come.

Fin Whale Nirvana!
There has been a certain level of magic with our whale watching trips this season. Every trip is different, but this year, each trip is very different from the last and we lay witness to beautiful and unexpected encounters at sea. Yesterday was no exception, but for a short while, it did not feel that way. Our sunny skies turned gray shortly after leaving the dock and there was a strong, gusty wind with a bit of chop. The usual sightings of bottlenose dolphins near the lighthouse were lacking and as we headed south towards an area where whales and dolphins were bountiful on previous trips, we saw few birds and no cetaceans. Then we headed east, putting the strong wind to our back, and turning toward sunny skies as if a switch had been flipped. Almost immediately, a small pod of short-beaked common dolphin charged toward the vessel and swam around the bow, but only briefly. We waited and searched for more, but this would be a fleeting encounter. We continued steaming and searching, and after a little while, the dolphin pods returned, and this time, they remained. It was a small group and more mellow than the charging pods we have seen on previous trips, but these rode the bow and swam alongside (and under) the vessel for nearly 20 minutes. Everyone had excellent, lingering views. Then a blow was spotted and we quickly investigated it. The single blow became two and we found two finback whales about 200 yards from the vessel. But there was a third finback behind the vessel and more blows were spotted in the area. These belonged to six additional finback (fin) whales with blows belonging to at least six other fin whales ahead of us. Fin whales are incredibly fast and notoriously tricky to encounter, but that was not the case yesterday! The magic returned and we were surrounded by a dozen fin whales, with groups of two, three, and five popping up around our vessel. The second largest animal on Earth, these whales were HUGE and we soaked in their sights and SOUNDS as they exchanged breathes at the surface. It truly was a magical and rare encounter. Unfortunately, we had traveled so far to find them, it was eventually time to head home. Blows continued in all directions on our return and a surprise humpback whale was spotted diving ahead of the vessel. We paused our transit to investigate and were elated to see this whale surface again revealing its tail flukes on a terminal dive, marking the perfect punctuation to another incredible day at sea.

Another successful trip with 5 species of cetaceans and a loggerhead sea turtle!
A rich diversity of marine mammals and sea turtles were seen during today's trip on the Viking Starship. The capacity crowd got to see things that many had never seen before. We headed to the same area where we've been seeing whales and dolphins for a few weeks. It's actually an area that used to be the prime area for sightings for decades! Near Montauk, we encountered a small group of Tamanend's bottlenose dolphins (Tursiops erebennus). Offshore, in view of the Block Island Windfarm, from miles away, again, we saw the splashes of breaching whales and the blows of humpback and finback whales. A few minutes before encountering our first whale, we encountered a loggerhead sea turtle (Caretta caretta) and were able to see it and photographic it eye-to-eye using a zoom telephoto lens at 600mm. Shortly thereafter, our encounters with cetaceans began: fin whales (Balaenoptera physalus), humpback whales (Megaptera novaeangliae), short-beaked common dolphins (Delphinus delphis), and common bottlenose dolphins (T. truncatus). While the pelagic bird sightings were low, we still managed a few when with the whales. The seas picked up and wit was a bouncy ride on the way back, but none-the-less, a spectacular trip!

We headed out after the effects of Hurricane Erin were settling down. Often after these kinds of events, we are sure what might become of the whales' prey and the whales. We decided to head towards where we had been finding whales over the past few weeks. We were pleasantly surprised by finding whales significantly closer than we expected. At first we saw the characteristic towering blows of finback whales, a mom and her calf. After a while, we headed towards a nearby pair of humpback whales, also a mom and her calf. In both cases always a special treat to see.
The humpbacks could be seen open-mouth feeding and filtering - again, always a pleasure to see, whether you're a newbie or have been at it for nearly 4 decades. We ended the trip while looking at our 5th humpback, unfortunately like too many, it had lost its dorsal fin, but otherwise seemed well. Human interactions such as ship-strikes and entanglements are the predominant causses of whale deaths and injuries. We can all do better. CRESLI and the Viking Fleet are members of the Whale SENSE program and always interact responsibly and appropriately when with marine mammals.

Only two days after Hurricane Erin stirred up nearly 20-ft seas off Montauk, we headed off unsure of what we may or may not encounter. Shortly after steaming beyond the inlet, we encountered a small pod of Tamanend’s bottlenose dolphin, a species we typically find much closer to the open ocean beyond the Point. We continued on after a short stop and found a humpback whale just a couple of miles southwest of Camp Hero State Park. We spent time with this whale, a juvenile, which would surface every three to four minutes, likely feeding on bait detected near the bottom. We eventually headed east where humpback and finback whales were spotted the day prior. Almost immediately, more Tamanend’s bottlenose dolphins were spotted, in small groups at first, not exceeding 20-30 individuals per pod. This continued for a few miles of transit with the pod size and pelagic bird sightings increasing along the way. We passed through the area where whales were seen the day before without any sightings so continued east where whales and dolphins were documented throughout the season. Unfortunately, the area was barren so we circled back and searched familiar areas again. Shearwaters (Cory’s and Great, mostly) and Wilson’s storm petrels were abundant, but no whales would be found. A large splash made likely by a humpback whale was observed by one of our sharp-eyed volunteers at least a few miles away and we headed in that direction to check it out. Unfortunately, despite keen eyes and eager passengers keeping watch, the whale was never seen and it was time to return home. Thankfully, we enjoyed good sightings earlier in the trip and a beautiful sunset upon our return, but this was a reminder of the dynamic nature of the ocean and the animals within.

Not wanting to repeated the previous day's effoprts, we headed out to investigate several different whale spotting territories and had success
The conditions were excellent, the visibility was limitted to around 5 miles at first, but opened up to at least 14 miles. We headed south soon found a scalloped hammerhead shark and a few pelagic (open ocean) birds, before we eventually found two humpback whales in an area where the depth was 125' and their prey (most likely sand eels) were patchily distributed on the sea floor. One whale was ahead of us and one on our stern, Both dove several times before any photos were taken, both stayed down for anywhere from 8-15 minutes. After the "last" dive was at 15:00 minutes long and counting, and we'd unseccessful in getting photo ID's, and had been with these whales for 27 minutes, we opted to leave and look for more. Away we went and the whales came up behind us after being down for 16 minutes.
We headed ENE for 2 hours before we found a mom/calf pair of finback (or fin) whales. The mom was enormous, probably near 80' in length and the calf was obviously smaller, but large enough. They also had potential prey far down in and around the sea floor and were diving for around 3:30 on average. Throughout the trip we had birders on board, monitoring and attempting to count all birds, but particularly wanted to see pelagfic (open-ocean) birds. Their sightings are posted in E-bird and they documented 36 species! I've included their counts for our pelagic bir compoonent of his report. The trip was long, but rewarding for all involved. My sincerest thanks to the group of 4 birders who's offshore trip with our friends and colleagues on the American Princess had been cancelled. Of course my thanks also go the Viking Fleet Captain (JR Gibson) and crew (John and Paulie), the 9 CRESLI voluinteers, andeveryone else on board (including the yellow warbler that hitched a ride back tpo shore with us)
