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.

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.

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!

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

‘FAMILIAR FECES’: CETACEAN POOP-SCOOPING BY SPECIES

UPDATE I name-checked BMMRO intern Oscar Ward’s blog below. Now he’s been out on the ocean on ‘poop patrol’. You can read Oscar’s account of his experiences HERE

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.

That’s enough on the topic for now. Later in the month there will be some great dolphin pictures to enjoy. Below is the BMMRO sightings chart for July, which I forgot to publish sooner.

Finally, a young UK friend of ours, Oscar Ward, has recently won his place to study marine biology at university next Autumn. He has just arrived on Abaco to start an internship with the BMMRO at Sandy Point. He will then be moving to Friends of the Environment in MH. He has set up an excellent blog to record his experiences, with his first Abaco post going up today, I notice. You can follow Oscar at SEVENTYPERCENT.COM And if you see him around, do say hi! to him.

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.

ABACO / BAHAMAS WHALE, DOLPHIN & MANATEE SIGHTINGS AUGUST 2012


ABACO / BAHAMAS WHALE, DOLPHIN & MANATEE SIGHTINGS AUGUST 2012 

ANOTHER PYGMY WHALE STRANDING ON ELEUTHERA

The BMMRO has posted the cetacean / sirenian sightings for August. The main concentration off Abaco is in the food-rich south-west coast from Rocky Point down to Hole-in-the-Wall. This is where the deep water of the Great Bahama Canyon meets the shallow underwater coast of Abaco, providing an ideal feeding ground for whales and dolphins. This canyon is the largest underwater canyon in the world.

Plenty of dolphins were reported last month, and the sperm whales (including pygmy and dwarf) were still around (but for some sad Eleuthera pygmy sperm whale news, see below). Meanwhile, the yellow spot on the Berry Is. shows that all is well with the manatees.

STRANDING NOTIFICATION: PYGMY SPERM WHALE 

Last week the BMMRO was notified about a whale that had stranded dead on an Eleutheran beach on 27 August. The species was identified from the photographs as a pygmy sperm whale – the same species that stranded on the other side of Eleuthera the previous week.

Thanks to the Stranding Network, it was possible take a tissue sample and teeth for DNA, as well as more photos.The animal was about 6 feet long and moderately decomposed – possibly dead for up to 3 days. Unfortunately due to the state of decomposition a cause of death could not be determined. However more information about the animal will be obtained from the samples taken. With samples taken, the carcass can now be buried.

Actually, I say ‘Abaco’ but the most activity - and the most varied, species-wise – is off the southern coast of Grand Bahama. Abaco sightings are also confined to the south, with shows from a PIGMY SPERM WHALE and a BLAINVILLE’S BEAKED WHALE  and dolphins in the arc between Rocky Point and Hole-in-the-Wall.

The manatees of the Berry Is. are no longer shown on this map. Their happy story (and their fame) has spread and they now have their own entries on the BMMRO FACEBOOK PAGE, like any self-respecting stars. You can reach it anytime direct from the Sidebar if you you want to keep track of the story of Rita and her calf Georgie’s rehabilitation – and the other manatees they have encountered as they get used to their freedom.

BMMRO WHALE, DOLPHIN & MANATEE SIGHTINGS / WINTER REPORT


BMMRO WHALE, DOLPHIN & MANATEE SIGHTINGS AND WINTER REPORT DECEMBER 2011

This was an interesting month. For a start, a humpback whale was reported off Elbow Cay, and a sperm whale further out to sea to the east. There were several cetacean reports between Sandy Point and Hole-in-the-Wall. Perhaps best of all, West Indian manatees – mother and calf – were reported in the area at the end of December, just off the Berry Islands – photo below, and further details in the BMMRO Winter Newsletter via the blue link.

THE WINTER NEWSLETTER contains much of cetacean interest, as always. It features articles on the effects of climate change of the declining Sea of Abaco bottlenose dolphin population; manatees in the Bahamas; ‘Life after Death’ – the importance of whale carcasses on the deep sea eco-system; sonic body-length measurement of sperm whales; the false killer whale stranding on Guana Cay (see POST); educational news update; and much more besides

BMMRO NEWSLETTER WINTER 2011/12

Courtesy of NAHRVALUR and her excellent wildlife blog, here is a cute view of a manatee in a Florida Reserve, where a webcam has been installed 

Manatees (family Trichechidae, genus Trichechus) are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis), the West Indian manatee (Trichechus manatus), and the West African manatee (Trichechus senegalensis). They measure up to 13 feet (4.0 m) long, weigh as much as 1,300 pounds (590 kg), and have paddle-like flippers. The name manatí comes from the Taíno, a pre-Columbian people of the Caribbean, meaning “breast”
I’ll write a separate post about these creatures later, and cross-refer from here. rh
