MAKING A SPLASH: SPERM WHALES & MANATEES IN ABACO WATERS

After a quiet spell on the cetacean and sirenian front, there is exciting news to report. First, the BMMRO encountered two sperm whales just off Sandy Point.  I don’t know how close to the shore they actually were, but it was very friendly of them to come so near to the BMMRO HQ.Sperm Whale, Sandy Point, Abaco BMMRO3

When whales are sighted from the research vessel, one of the tasks is to collect feces. This job is often undertaken by interns, and is a good way to learn that serious research may well involve unattractive work… They practise with… er… coffee grounds and a net. For more on this important yet unappealing aspect of whale research, CLICK NICE TO SEE FAMILIAR FECES. Another essential part of any sighting is to take fluke photos to enable ID.  Every whale has different and distinctive patterning to the fluke, including general wear and tear. As a photo archive is built up, the researchers are able to recognise a particular whale and cross-reference it with previous sightings.

The third task of a sighting is to record clicks made by an individual whale. This enables an estimate of the whale’s size to be made, and again a sound archive is gradually built up from which comparisons can be made.

A NEW MANATEE VISITS MARSH HABOUR

FRIENDS OF THE ENVIRONMENT has just reported the sighting of a new manatee at the head of Marsh Harbour harbour. I’m not aware of any other sightings in the last couple of days, but as they say,  “Please keep your eyes out and drive carefully! Contact Bahamas Marine Mammal Research Organization with any further sighting reports by calling 357-6666. You can also share photos with them on Facebook. Also, please do not feed the manatee. They are able to find their own food and anything else may make them unhealthy”.

This is Abaco’s third recent manatee. First there was GEORGIE, who as far as I know is still comfortably settled in the Cherokee area. Then RANDY arrived earlier this and got to within about a few miles of Georgie… High hopes of a meeting – and ‘friendship, maybe more’ – were dashed when Randy turned round and headed back to Castaway Cay. Let’s hope this newcomer stays around. I wonder what he – or she – will be named? My suggestion is Abby or Abi, which I think is unisex…

Just as with the whale flukes, the tail of a manatee is an important means of identification. The new manatee’s tail has its own distinctive edge pattern, which will enable its future recognition. Here is an image of Randy’s tail, with its unique notch.

CETACEAN SENSATION: SPERM WHALES & DOLPHINS ON ABACO

July has been ‘Whale Camp’ month for the BMMRO, when a small group of lucky youngsters get to spend time out at sea searching for whales and dolphins, and learning the intricacies of data recording and research. One target was the sperm whale, a species that may be found off the coasts of South Abaco. This is a favoured place because the deep trench of the Great Bahama Canyon throws up the food these whales need (see map below).

After some time spent searching, the BMMRO reported  “the sperm whales are back! We found a single animal yesterday, and finally in the evening found the rest of the group, 10+ animals including 3 mother-calf pairs, and dolphins at Rocky Point!” Here are some of the photos from the trip.

This map of the northern Bahamas shows the V-shaped tails of the Great Bahama Canyon, and explains why the east coast and (in particular) the shallower south-west coast between Hole-in-the-Wall and Rocky Point is so attractive to feeding whale species.

The dolphins were quite prolific in July, in particular bottlenose and spotted dolphins. These photos were mostly taken while the search for sperm whales was going on: the BMMRO posted “lots of dolphins up at Gorda Cay yesterday… still not hearing any sperm whales in the area, has been a couple of weeks without sign of them so they should be showing up again soon…” As they obligingly did!

Today is the first day of the crawfish season and Facebook Abaco has been crawling with crawfish for a couple of days in feverish anticipation. So I decided to stick with whales and dolphins instead because there are enough crawfish images out there to keep anyone happy. However I did particularly like this offering today from Albury’s Ferry Services, always a byword for tastefulness and decorum. I’ve borrowed their picture (they borrow mine sometimes) – I wondered if it need a little more exposure, then decided there was probably quite enough already….

The BMMRO (Bahamas Marine Mammal Research Organisation) had a great June for sightings of cetaceans and sirenians. Here is a sample of their wonderful photos from recent research expeditions (with thanks as ever for use permission).

RANDY THE WEST INDIAN MANATEE

After the recent excitement of Abaco’s manatee GEORGIE having returned to Cherokee after another of her epic journeys, another West Indian manatee has arrived at Sandy Point (conveniently the location of the BMMRO HQ). Sirenians and cetaceans are generally recognised from particular patterns to flukes or fins. The second image shows the notch in Randy’s tail that confirms ID.

Stranding Response to Support Conservation of Marine Mammals in the Bahamas 

Increasing capacity and available funds to respond rapidly to strandings in The Bahamas will increase our ability to determine cause of death and/or successful rehabilitation of marine mammals. At the first stranding workshop held in the Bahamas in 2008, the Honourable Lawrence Cartwright, Minister of Agriculture and Marine Resources officially opened the workshop stating “I believe the establishment of a Marine Mammal Stranding Network in The Bahamas will serve to promote the conservation of marine mammal species and their habitat by improving the rescue and humane care of stranded marine mammals, advancing stranding science, and increasing public awareness through education.” This funding will provide the resources to train veterinarians on how to work with stranded marine mammals as well as provide the resources to respond to strandings.

Field Research & Outreach to Support Conservation of Bahamas Marine Mammals

Cetaceans are long-lived, highly specialised animals with delayed reproduction and low fecundity, which makes them incapable of rapid adaptation and thus particularly vulnerable to anthropogenic impacts. BMMRO has compiled an unprecedented long-term dataset for the region, which has become increasingly valuable to inform about the baseline ecology of some odontocete species. This research will ensure that this important work continues to fill key gaps in our knowledge about the ecology of marine mammals. Additionally, we will increase awareness and build capacity amongst Bahamians, both of which will contribute to local conservation needs.

JANUARY SIGHTINGS

For Abaco, the excitement is the sperm whale seen just off the Rocky Point area. More generally for the northern Bahamas, in addition to the manatee Georgie (former temporary resident of Abaco) and others, there was a manatee reported on Eleuthera. It looks as though these gently creatures continue to find the area to their liking.

3 MONTHS ON ABACO WITH THE BMMRO: AN INTERN’S STORY

My name is Jack Lucas and I am Marine Biology Student at Plymouth University in the UK. I came to the Bahamas Marine Mammal Research Organisation on Abaco in July 2013 for a 3 month internship, which has been an amazing experience from start to finish. Heres a summary of my summer spent at BMMRO.

Sperm Whale Fluking

I arrived at the start of July and was fortunate enough with my timing to be part of an assembled crew of scientists from all over the world coming together to start work on what was to be this summers main project; collecting faecal samples from Blainville’s beaked whales to assess stress hormones produced. This team included Dr Roz Rolland and Dr Scott Kraus from New England Aquarium, who are collaborating with BMMRO for the work, and the samples will be analysed back at their lab in the US. Also along for the ride was Roxy Corbett; a whale observer and field researcher from the US, and Dr Stephanie King; a acoustician from the Sea Mammal Research Unit in Scotland. The first day after arriving it was straight out on the boat to search for these elusive creatures and the beginning of a crash course in how to collect and store the faecal samples when we found them. For the first week the work was a mix of boat work when the weather permitted and practicing poop collection using custom-made fine-mesh nets and coffee grounds (as close to the real thing as we were willing to try!), as well as clearing out BMMRO’s garage and, under the direction of foreman Scott, the construction from scratch of a lab to prepare samples for storage.

An example of the use of coffee grounds to practise whale poop-scoop technique269RH note: NOT Jack’s arms / snappy diving suit…

Unfortunately, despite days of poop collection practice and endless hours searching for the whales at sea, the original poop team never got a chance to employ these by now highly developed skills or to see the lab being used, as the weather was so windy we barely encountered the animals let alone spent long enough with them to collect any samples. 

Despite the lack of beaked whales, we did encounter loads of marine mammals in the first few weeks, from sperm whales to three different species of dolphin; including the little-seen and even less-studied rough-toothed dolphin.

Rough-toothed Dolphin

After discussion with Charlotte and Di about a possible project for me to complete during my stay, it was to be this species that I would focus on and in between the usual office jobs it was my task to sort through the photos from 20 rough toothed encounters in the Bahamas since 1995 and create a catalogue of individuals. This initial task consisted of careful inspection, comparison and sorting of what turned out to be over 5000 photos, into an organised catalogue of 167 separate and distinctive individuals. Despite the hours of endless staring at fins, it was very rewarding as there were 13 resighted individuals found (we were not necessarily expecting any!) which suggests long-term site fidelity and association of these animals, in addition to year round use of the Grand Bahama Canyon. Even more rewarding; the results of this work have recently been submitted for a poster display at an Odontocete workshop in New Zealand this December and I am also writing up the results in a formal scientific paper, with the hopeful goal of publishing a note in a peer-review journal. 

 Scott, Jack, Stephanie and Di in the new lab at Sandy Point

Around a month in I was lucky enough to be sent by Di and Charlotte to Great Harbour Cay on the nearby Berry Islands to work with the manatees there, in particular Georgie; a recently released juvenile whose status is being carefully monitored after her rehabilitation at Atlantis’ Dolphin Cay following health problems. The work here for a week under the guidance of Kendria; a Bahamian contracted by BMMRO to monitor the manatees on the Berry Islands, consisted of tracking Georgie using a satellite tag attached to a belt around her tail. Once located, we logged her position and made any notes on her health and behaviour aswell as the other manatees that were often found with her (there are currently 6 located on Great Harbour Cay). Two days in her tag was found unattached at a locals dock (it has a weak-link incase of entanglement) and we had to locate her using underwater hydrophones to detect her belt. Once found, I had the rare opportunity of entering the water with her in order to re-attach a new tag to her belt; it was amazing and one of the best encounters I have had with any animal! It is impossible not to love these amiable and gentle creatures, especially when you observe their infamous ‘hugs’ in person! 

Georgie the Manatee

For more about Georgie’s re-release in the Berry Is. after her earlier shenanigans on Abaco, see HERE

After returning from the Berry Islands (and incidentally missing the first two poop collections of the season made by Charlotte!) it was back to hunting for the elusive beaked whales around South Abaco. During my time I had the chance to work with several interns coming to BMMRO including local marine-enthusiasts Tristan and AJ, and Courtney Cox from Florida. Oscar Ward from the UK also joined the team as Charlotte left for Scotland to complete her PhD, and was on hand during the poop-collection and other little excursions. In wasn’t until the last month of my time here that we managed to get close enough to the whales for me to get in the water and be towed alongside in the hope of seeing one defecate. One amazing morning two whales surfaced right off the bow of the boat and what resulted was again, one of the most amazing moments; swimming just a couple of feet away from an animal only a handful of people in the world have seen underwater. After nearly two months with no samples, the two weeks that followed were a flurry of boat days, poop-collection and whale watching; with a total of 7 samples collecting from beaked whales (5 in one day!!) and another 3 from sperm whales. This was the best possible end to my time here and I finally got a chance to use the much-practiced poop collection techniques. The samples included a number of squid beaks, and in one very deep dive collection a mass of parasitic worms and a weird cephalopod-type animal! We also got a chance in the last few weeks to test-run a new addition to the fleet, that included a dive compressor.

Ready to collect some poop…

Finally my time in the Bahamas had to come to an end, and I had to return home. The last 3 months has flown by and has been one of the most enjoyable and most importantly educational periods of my life and I cannot thank Di and Charlotte enough for making it all possible. The day-to-day boat runs, office work, equipment maintenance and station chores has given me a good insight into all aspects of field research. It was my first taste of life as a marine mammal scientist, and it has made me even more determined to pursue a career in this field; a perfect stepping stone from which to move forward. In addition my work with BMMRO (and what must of been a brilliant reference from the girls!) made it possible to secure a highly competitive internship in the Farallon Islands this winter tagging elephant seals amongst other work! I cannot wait to continue working in this field and finish writing up the results of my project here, and hope I have the chance to come to Abaco again to work with these amazing people and animals!Sperm Whale supplier of poop BMMRO

Among the many pleasures for cetacean research scientists must be the joy of whale poop collection. Followed by close inspection and analysis. The Bahamas  Marine Mammal Research Organisation BMMRO conducts research expeditions, in conjunction with such organisations as the New England Aquarium NEAQ and Friends of the Environment FOTE, in Abaco waters and further afield in the Bahamas. The attention this year has been on beaked whale feces, though available sperm whale feces are not to be sniffed at.

ABACO WHALES & DOLPHINS: BMMRO SIGHTINGS & NEWSLETTER

I haven’t posted Abaco whale, dolphin & manatee news for a while. Time for a catch-up. Georgie the young manatee that left her mother Rita and came to Abaco from the Berry Is. alone, is no longer here. She survived a very long journey, and investigated various coastal areas of Abaco – all the while being tracked. In the end she settled down in the Cherokee area. There were anxious times during Hurricane Sandy when she went missing (having by now shed her tracking device) but she eventually reappeared at Cherokee having found a safe haven from the storm. Sadly, however, her condition deteriorated and in the New Year she was relocated to Atlantis Dolphin Cay Marine Mammal Rescue Center. Some weeks ago a healthy Georgie was moved to a sea-pen to acclimatise her for release back into the wild.
