Double-crested Cormorant
... Double-crested Cormorant is an opportunistic feeder and will predate on a number of fish species (generally less than 13 cm long) including herring, minnows and stickleback, as well as juvenile salmonids. Aquatic invertebrates and (rarely) small vertebrates other than fish will be taken. Foraging di ...
