There were some recent articles about cormorant nesting colonies in the Salish Sea and the conclusion of the authors was that it was a relatively new phenomena. They weren't nesting insound until recently and even the coastal colonies were in more inaccessible areas to keep humans away, as they collected the eggs. Have to see if I can dig up the specific articles.

I've been doing some reading, digging up as much as I can find on the cormorants on the lower Columbia River highway bridges. A colony has formed on the Lewis and Clark bridge at Kelso as well. Best I remember, they're all double-crested cormorants.

Pelagic cormorants nest at the Warren Ave bridge in Bremerton (also a state highway bridge) and on dolphins at the Anacortes ferry terminal. It's my understanding that virtually all north Puget Sound Pelagic cormorants are now nesting on man-made structures, having abandoned the natural cliff/bank sites.

Interesting article! A couple of the photos actually look like Anhingas to me! The bridge nesting cormorants are likely Pelagic Cormorants.
