Mystery (to me) Bird

What is this sea bird?

I don't remember ever seeing this kind of bird before, at the beach I've spent a lot of time at over the years, just south of Boston. There's no oil in the area at all, they're just drying their wings it looks like. They're maybe twice the size of the ubiquitous white-and-grey gulls. What are they? I'm wondering if they're out of their usual range.

Those are cormorants.

Yes, Cormorants. This behavior is quite typical and has nothing to do with oil.

Best answer: yes, cormorants. the 'drying their wings' thing is the big tip-off there (other than the picture). it's just something that they are known for.

Best answer: Yep, cormorants, probably double-crested cormorants. The wing-drying thing is related to their plumage: cormorants' feathers aren't entirely waterproof, so they can dive faster, but they also need to dry out their wings afterwards.

I believe they lack the same oil as other sea birds that keep them dry. It allows them to be less buoyant and are therefore able to dive farther for food.

Wow, cool, a cormorant! As soon as I saw your picture, I thought of watching men fishing with cormorants near Yangshao.
