Now you guys are talking. commorants eat there weight in fish each day. you might pick on off while flying and theres always that chance it well come down on the poacher hiding on the other side of the river...well one can only hope. The great lakes has huge flocks of them they look like a distent black cloud when flying low to the water. Ive seen them sitting up on that old bridge buttment just south of concrete. you know they are not there eating candle fish or herring. The thing I noticed this year is they are not there when the eagles are around....DJ
