In my opinion and observations, cormornats are eating more than their share of Puget Sound salmon and more importantly, WILD STEELHEAD SMOLTS!
On the Columbia the situation has finally attracted the attention of the U.S. Army Corps of Engineers. If the USACE is successful, will even more Columbia River mouth cormorants come here?
