During the first week of July, I celebrated my birthday and US independence, but I was also joined dolphin trips with Bimini Adventures. Although I was not collecting video/acoustic data, I was collecting our usual sighting data and still photographs when I could. On Monday, we started the day with a bottlenose dolphin sighting; there were two dolphins not far from Bimini’s shore. Later we saw six spotted dolphins, including Niecey (#48), Romeo (#10) and, possibly Noodle (#94). We had a great underwater observation of Split Jaw (#22) and an uncatalogued young male spotted. On Tuesday, it was a pair of young spotted dolphins, including un-named #95. Wednesday, there were again bottlenose dolphins early in the trip. We observed this group of three while they were crater feeding before continuing in search of spotteds. The spotteds we found were all older, including un-named #75, but they were more interested in surfing the swells than checking us out under water. The final trip of the week, Thursday, was beautiful, although the underwater visibility varied greatly depending on our location. On this day, female spotted dolphins dominated our sightings!
It was a pleasure accompanying this NHK crew. Thank you! Kel |

Friday 29 June was another rare morning dolphin trip with Bimini Undersea. This time, we headed out shortly after 9 a.m. and it was approximately 2 hours later that we saw the dolphins: a mixed species group with at least 11 individual dolphins. At first we saw Leslie (#80) and her calf, and Lil’ Jess (#35) and hers. As the sighting progressed, we got better views of the bottlenose as well as our spotted friends, Split Jaw (#22), Prince William (#64, pictured here), Speedy (#78) and Tilly (#87). Under water, we got a quick, but nice view of Prince William and a bottlenose dolphin. Speedy and Tilly were front and center for a bow ride as we said goodbye to the group and headed home.
Until next time, Kel |

After a week of wind, rain and more wind thing finally cleared up on Thursday (28th June) for us to go in search of dolphins. Although we were not in Tropical Storm Debby’s path, the surrounding weather pattern did make June seem more like January. The group’s patience was rewarded on Thursday and Bimini Undersea took the group out for two dolphin trips (an uncommon practice, to be sure we give the dolphins ample time away from the boat and our interactions). The morning trip included a long awaited dolphin sighting. Although we did not get to swim with these dolphins, we got incredible views of a group of at least 13 bottlenose dolphins. They came surprisingly close to the boat as they swam in a fairly close formation. We took a break for lunch and headed back in search of dolphins later in the afternoon. This trip brought more bottlenose dolphins: first, a single bottlenose and later, three to five bottlenose, including a mother/calf pair! The calf is pictured here.
It was so nice to get on the water after so many days on shore! Until tomorrow, Kel |

This just in from our friends at the United States Geological Survey (USGS): "Harold," the manatee who visited Bimini in 08/09 and was subsequently relocated to Florida, was seen in the St. Marks, FL area by the USGS Sirenian Project in June - he's looking good! His distinct scar patterns will allow researchers to recognize him in the years to come. Thanks for the update USGS!

On Father’s Day I was again aboard a dolphin trip with Bimini Adventures. The seas were completely different from Friday with the winds strong from the northeast. Still, we searched and searched for dolphins, finding them several hours into the trip. At first we saw Tilly (#87) and an older calf (or young juvenile?!) who were quite busy surfing. It was a challenge to keep our eyes on the pair and we soon found ourselves backtracking, hoping to lay eyes on them again. While we did not find Tilly and her “friend,” we did see two calves. The slightly older of the two is thought to be Leslie’s (#80) calf (with remora in tow once again) so we were on alert for her. It was an unusually long time before we finally saw the (presumed) mothers – one an older dolphin and one younger, possibly Leslie (#80). The foursome surfed a few more waves before once again going out of sight. So, although it was a rocky boat ride it was great to see so much of the dolphins!
Until next time, Kel |

Friday was another great day of summer weather here in Bimini. I headed out shortly after 1500 with Bimini Adventures and a great group of passengers. We headed toward the “dolphin grounds” quickly and before we could even warn folks that it can take a while before we see dolphins, there they were…a group of at least 15 bottlenose dolphins. They were swimming in a fairly tight group, as seen here, so given the sea conditions we were able to get a great look at them from the boat. They were on the move so after watching them from the boat, we decided to move on too.
Despite the wildly calm waters, we did not see so much as a splash for the next two hours. Shortly after 1800 we once again came upon bottlenose dolphins, this time a pair that was even less interested in us. We were gaining interest in the building squall nearby as we made one last run in search of dolphins. Then they were finally there! At least eight spotteds, including Lone Star (#56), un-named #40, calves and juveniles appeared. A short underwater look was all we could manage before we had to leave the area. As we cruised back toward Bimini we saw two other groups of spotteds and by the time we reached the third we were far enough from the squall for the passengers to have a quick swim. It may have been brief, but boy was it intense! Today surely met the definition of wild dolphin trip!
Until next time, Kel |

Thursday brought with it an unexpected dolphin trip with Bimini Undersea. The conditions were as favorable as they get, with seas that resembled a swimming pool more than the ocean. With a great group of passengers onboard, we did not have to wait long before we saw dolphins. It was another large group and shortly after our observations began, we noticed three bottlenose dolphins in the midst of the spotteds. There were at least twenty individual dolphins over the course of the sighting, including Trudy (#57) and calf, Prince William (#64, pictured here), Tim (#69), Speedy (#78), un-named #40 and calf as well as #75. We saw Juliette (#12) and two calves (only one is hers) as well as “the boys” and the three bottlenose dolphins under water. There was lots of mixed species socio-sexual behavior going on and it made for a great observation.
As we headed back toward show, giddy with excitement, a few more spotted dolphins came to the bow: Split Jaw (#22), Lil’ Jess (#35) and calf and Leslie (#80) and calf. I am now fairly confident that we’ll be able to add Leslie’s calf to the photo-ID catalog as it has some serious scarring to the peduncle. It also has a fairly large remora – I don’t know what it means, but I do know that during each observation in 2011 and so far in 2012, this dolphin calf has had a remora on it. Could it be the same remora after all this time?
There is another dolphin trip tomorrow, so stay tuned! Kel |

Friday began (relatively) early as I saw Kathleen to the North Bimini water taxi to begin her journey back to New England. Unfortunately, some harsh weather was on its way, leaving her stuck for most of the day at the South Bimini airport….
Meanwhile, I tidied up a few computer files while standing by for the final call on the day’s dolphin trip. A few hours and several power outages later, the trip with Bimini Adventures did depart. The skies cleared just long enough to safely head in search of dolphins. We didn’t have much time before the next round of thunderstorms came through, but thankfully the dolphins were sighted right away. We saw at least eight different Atlantic spotted dolphins, including Swoosh (#36), Niecey (#48), three calves and Addie (#84). I was able to use the MVA4 to record Bimini dolphins for (I think!) the first time! I’m looking forward to reviewing the footage!
The passengers kept their spirits high and their smiles wide as we returned to the dock under an impressive downpour. Now we’ll wait and see what tomorrow holds!
Until then, Kel |

On Wednesday the weather was in our favor for Bimini Adventures’ dolphin trip. We departed the dock at 1300 as we planned an extended snorkel stop at “3 Sisters.” The dolphins would not have us rush to that conclusion, however, as we were greeted by at least seven bottlenose dolphins immediately after leaving the harbor. The dolphins were on the move, so our observations were exclusively from the boat, but the flat-calm, Bimini-blue water made for a fantastic backdrop and very good views. As the dolphins continued south, we headed north, happy with the cause for delay.
After a great snorkel stop we continued in search of dolphins and did not have to wait long. We came upon eight Atlantic spotted dolphins, including un-named #40, three other adults (females?) and 4 calves. As the day worn on the group size increased and we eventually saw Split Jaw (#22), Swoosh (#36), Trudy (#57) and calf, Stefran (#57) and calf, Prince William (#64, pictured here), Speedy (#78) and Inka (#93). With at least 25 spotted dolphins making an appearance, it was a great day!
Tomorrow Kathleen passes through Bimini, by then having wrapped up the Ethological Studies course. We have a lot to catch up on!
Until next time, Kel |

When we first arrived, we helped do a bit of research –
Kathleen deployed the “yellow baby” (aka the SM2M unit) and also helped Rebecca
finish up some of her control sessions. We were then guinea pigs and got to
snorkel in the new snorkel area being planned for guests between the sea lions
and dolphins. We saw a HUGE lobster and a few tinier fish.
After our snorkel, we got the chance to watch a sea lion
training session and encounter. The sea lion was PJ who starred in the movie
Andre and also PJ & the Stinkers. The trainers use a vocal bridge instead
of a whistle as for the dolphins. The hugs and funny faces the sea lions make
are just hysterical.
We then had lunch and got to play on some of the inflatable
thingees – it was fun. But, then we saw little thimble jellies and we decided
to get out of the water.
The afternoon brought us to our swim with the dolphins. This
was very cool and really fun. We got a hug, a kiss and did a few dances before
we had foot-pushes.
We wrapped up the day with an extra snorkel – we were in the
water lots today! And, since it was a day mostly with sunshine, we all got a
bit sunburned.
We head home tomorrow – but we learned a lot and did many
different things!
Tomorrow, we travel home.
It has been a great class!
Cheers

We got lost on the way to our beach clean up and got to see more of the island. When we finally got there, we had lots and lots of trash to clean up. There were log sheets to have an idea of the type of trash that was collected.
Lunch was had at the fish fry – specifically at Goldie’s – and several of us tried Bahamian food. This included Bahamian mac and cheese, plantain, and cracked conch. The food was delicious!!! We all had a taste of sky juice … very sweet.
We then walked about half a mile to the downtown tourist area of Nassau and spent some time in the Straw Market. It was VERY touristy and people-watching was great. We also received firsthand experience with bartering island style.
It was a good day overall.
Tomorrow is our last day at DE and includes more research and our swim with dolphins.
Until Then,

P.S. This, the second photo from Monday, photo shows Kathleen holding the SM2M unit to collect click trains from the dolphins.
The audio file (below) depicts about 15 seconds of clicks. We have collected a good amount of data with the new ultrasonic click detector added to our SM2M.

We had our dolphin encounter on Monday – we got to dance with, get a kiss from, and hug a dolphin. The encounter, with Missy, was awesome! The dolphin skin felt like a hardboiled egg.
We also learned about husbandry behaviors and why they are important for dolphins. Then, we went to the classroom and had a chat with Sara – the vet tech for DE. She shared with us details about the various medical procedures that might be needed with sea lions and dolphins, and the other critters at Blue Lagoon Island (e.g., Iggy the Iguana, the fish and birds, too).
It was nice and sunny all day long – our lunch was delicious and in the sunshine which was great! Linzi gave us the history of DE and how Blue Lagoon Island came to be and then Kim gave us a talk about approximating voluntary blood draws from dolphins. It was cool to see Kim with the dolphins – she is mom and the dolphins look up to her. The dolphin flukes present the veins that are really easy to see – once you know where to look for them.
Then, we started Dr. Singer’s research – we started with the boys. We were quite successful with the first two (Stormy and Jake) and then Goombay kept getting distracted by Jake so his trial did not go well. So we moved on to the girls. In all, Dr. Singer was able to complete control trials for 15 dolphins today! The photo depicts her doing a trial with Jake.
We finished the day with birthday cake and a song for Mikkah! J
Tomorrow is our beach clean up and visit to Ardastra Zoo.
Until then,

We woke very early to head to Dolphin Encounters (DE). It was just getting light and we had a nice morning walk to the ferry port for our ride to Blue Lagoon Island. The rain followed us to DE, and arrived the same time we did.
The dolphins greeted us, which was cool to see and hear. Annette oriented us to the facilities and gave us name-specific ID badges. We helped put together Dr. Singer’s apparatus and ran through practice on how to work it … i.e., practice trials. Then we helped Dr. D. collect data with her yellow tube (aka SM2M).
We had what one student has called “the best chicken sandwich ever” for lunch. After lunch we had a short bit of time to sit on the beach. Then, we collected more data and sketched the dolphins. We tried to see and remember the ID marks on each dolphin. Ranaldo, one of the awesome trainers, introduced us to Jake, Stormy, Goombay and Sean. We got to help a bit with training and then got to learn a few training signals from Ranaldo. In this photo you can see all of us on Swim #3 platform with Sean, Goombay and Stormy leaping for joy behind us. Note Jake hiding behind Brooke on the far left. He was camera-shy today!
Tomorrow we have our encounter, followed by more research and maybe a snorkel.
Until tomorrow,
The 2012 ECCs
P.S. Oh yes, we also had a lecture on Theory of Mind! |

It was sunny this Sunday morning! We ate pancakes! We swam with sharks!
The snorkeling was different from our snorkels in Bimini. It was cool to see lots of fish, but the dive masters were feeding the fish. It was not natural. The fish were almost in your face because of the feeding. The feeling was really touristy.
The shark snorkel was cool but it also was not natural – chum was put in the water after we had been in the water. The shark snorkel was not free swim. We had to hold on to a line and look down. After we were all out, then they chummed for the sharks to come right up to the boat.
We saw a few fish eating on the coral and the sergeant majors were protecting their little dens. We saw wrasse, jacks, damsel fish, tangs, parrot fish and stingrays.
Tomorrow is our first day at Dolphin Encounters – we are all quite excited.
Until tomorrow,
The 2012 ECCs

The day started early and beautifully! We needed to say bye to Kel, Al and everyone on Bimini for our trek to Nassau. We reversed our arrival by riding the ferry taxi to South Bimini for the airplane ride to Nassau. And then, we sat in the airport "forever" … our first sunny day in what felt like a week … spent inside an airport waiting for our plane to arrive.
We brought the rain to Nassau – flying threw a few thunderheads – but it didn’t last all day. We arrived to Sunrise Beach Condo and settled in. We have both pool side and ocean front access and views.
While Kathleen went to the grocery store, our E&E team played games … training games with skittles for rewards. The information was about operant conditioning. The evening finished up with a delicious spaghetti dinner and a hopeful, soothing and beautiful sunset. It was refreshing to see the sun today and we have high hopes for its return tomorrow morning.

It rained and stormed and stormed and rained. Our morning began (after breakfast) with a beach clean-up (photo to follow). We collected eight bags of trash from the beach, finishing up in a quick downpour. This beach clean-up was sponsored by DCP Conservation Member Steven. Thank you!
The afternoon showed quite a few storm clouds, but we went out for a short time for a snorkel trip. A couple of people were feeling seasick – we had pretty good waves rocking the boat. We did see two sea turtles near to the first spot we wanted to snorkel. The waves dictated that we move to a second spot. Seven people jumped in to snorkel but only briefly since the squall that was approaching forced us out of the water and back to port.
But, the end of the day finished with a rainbow (hopefully!) meaning tomorrow is going to be bright blue skies. Until then, The 2012 E & E Crew |

We woke up to rain and thunder, but that omen did not impact the bulk of our day. Although it did rain some more, we covered the topics of mirror self-recognition, an intro to dolphin behavior (and how to study it) and fish ID & lionfish invasion. The boat left at 15:30 and we had a beautiful snorkel at the big sister of the 3 Sisters. Among other fish, we saw tangs, foureye butterfly fish, squid, sergeant majors – but, we did not see any lionfish. Then we drove “forever” into the wild blue yonder in search of dolphins. When we did see dolphins, they preferred a large hull to our tiny bodies. But, we did get to observe them from the boat for quite awhile. They were riding the waves and the group size fluctuated from 4 to up to 17 individuals. Some of us did jump in the water, with increasing waves, but we did not see the dolphins under water. Over the course of the day we did the following dolphins from the boat: Romeo (#10), Lumpy (#17), Swoosh (#36), Tilly (#87), un-named #24 and 40, and, I think, Niecey (#48) as well as several un-marked calves. It was a chilly ride home, but our spaghetti and meatball dinner was a good fix!

DCP’s Field Course in Ethological Studies, with Georgetown College, is officially underway! The group started the program in Florida on Sunday with a simple layover before departing for Bimini on Monday morning. The plane to Bimini was the smallest that many of us had ever been on. From the air we could see how clear the water is – and how small Bimini is!
After we settled in, ate lunch and had an orientation we headed in search of dolphins. It was a very rewarding first day on the boat. On the way out we saw rays in the harbor and as we traveled, we saw flying fish. Our first sighting was of bottlenose dolphins and they were investigating and digging in the sand. There was a calf in the group. We also saw a nurse shark! We could hear the clicks and whistles underwater. Our second sighting was of Atlantic spotted dolphins and these were chasing fish. Some dolphins rode the bow and one was even belly up while doing it. It was very cool that wild dolphins came so close to us, despite not being trained. We even got to use underwater cameras. Later, the dolphins were surfing in the boat wakes – both in the stern and on the bow. By the end of the day we had seen Romeo (#10), Tina (#14), Split Jaw (#22, pictured here), Swoosh (#36), Prince William (#64), Tim (#69), Noodle (#94), in addition to all the bottlenose dolphins. The sunset on the ride back was beautiful and we came home to a nice BBQ on the dock.
Until next time, The 2012 Ethology and Eco-Tour Crew |
