The first thing a person encounters as they get out to deep water (which surprised me how common they were last year) is flying fish. Photographing them isn't super easy, identifying them is even harder. I don't know what this first one is, it was pretty large and could soar a couple hundred feet.
Black-capped Petrel was the first consequential bird we came across upon reaching the gulf stream.
Wilson's Storm Petrel is the most common seabird (maybe in the world) and they were behind the boat in at least some numbers much of the day.
To keep this post from getting too long I'm going to hold the highlight bird for the next post. We spent a lot of time in the deepwater, but didn't come across a ton of diversity. We started working our way back and came upon a collection of Cory's Shearwaters where the Gulf Stream meets the near(er) shore waters, still probably about 20 miles out. The warm tones of the Cory's conflicted somewhat with the cold blue ocean.
In this same area we came across a small group of Red-necked Phalaropes that tolerated close approach.
Red Phalaropes in the old boat a similar distance from shore in Lake Michigan a few years ago.
