We conducted an hour data collection session Thursday morning that had great underwater visibility, socially interacting dolphins (mostly with each other and not my fins!), and both the MVA and DTag in use. We captured many click trains and even some burst pulses. The following link is a sample of a burst pulse series from Ronnie. {audio}../podcast/RonnieBuzz.mp3{/audio} He had been investigating my fins and circle swimming around me. Then, he swam in front of me and looped back with the first 4 short bursts followed by the longer 3 calls.

Wednesday’s morning session brought 30 minutes of video of socially active dolphins. Maury and Bill were observed together often with Mika’s calf hanging close to Maury and sometimes positioning himself between Maury and Bill. It was the least active I have seen Maury in several mornings – she just seemed content to swim next to Bill. Hector, Han and Anthony, on the other hand, were a bit more rambunctious and were rolling all over each other. Mrs. B and Cedena kept their calves close as usual.

Tuesday was a good day with a one hour session in the early morning for data collection. We have lucked out with the weather; the morning sky was mostly clear and the sun brightened the view underwater early on. The underwater visibility continued to be EXCELLENT! Ronnie again had new rake marks on his back but that seems nothing new since he is still the instigator in the group.

I was in the water twice on Monday for a 30 min session (6:30 AM) and then a 60 min session (11:00 AM). The underwater visibility was 10 meters plus and it was clear with some sun, so it was also bright! The dolphins were quite social and very interactive with one another. On my first entry, Mika had Gracie’s calf! Mika’s calf was nowhere to be seen until I spotted Ronnie chasing him.

We had two morning data collection sessions – one at 6:30 and one at 10 a.m. The sky had a layer of cumulus clouds on the northern horizon which dropped a bit of rain on us early in the morning, but the later morning session had bright sun. The wind and current joined the sun making for an exercise-filled underwater session. The dolphins were very vocal early and Mika had Gracie’s calf when I entered. Mika’s calf was nowhere that I could see until about 20 min into the session when he was with mom again.

We were able to get one more session of data collection in this morning (early again) before Amanda, Amber, Kristin and Sarah had to finish packing their gear. The dolphins were active and vocal and provided a nice salute to our student observers. Even though the field portion of their class on animal behavior is complete, each student now has the task of reviewing and processing the observational data they collected and preparing a paper that includes their data and a literature review on their topics.

The next team includes Penn and Wu-Jung.

We started the morning early again … Kathleen was in the water at 6:37 am. The dolphins were VERY active this morning and we recorded lots of surface behavior. There was much rolling and various body parts splashed about at the surface. It was also our very first fully sunny day! That is, no clouds really to speak of, which led most of us to get a bit of sunburn.

Another early morning data collection session – an hour today with awesome underwater visibility (10 m plus) and very social, interactive dolphins. All four young calves were given the opportunity to inspect Kathleen and her green camera … with each mom hanging in the background so the calves did not get too close for too long. Actually, the dolphins might have requested Amanda’s clipboard so that they could document their observations of Kathleen. With their rostrums, the dolphins attempted to flip the clipboard over after it slipped into the sea and inadvertently tasted the data sheets.
