[Tweeters] Killing Cormorants to Save Salmon

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.

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.
