Creative idea. I always thought WDFW or USFW, or whoever, should release raccoons or coyotes or whatever, on the nesting islands of cormorants on the Columbia, to harass and eat the eggs and chicks. A few years ago some bald eagles did a number on a rookery and they left. Oh wait! When they left those areas they moved on the Astoria Bridge. Now fecal matter is eroding the steel of the bridge just after a new paint job. Smart birds.
