Now and then individual catfish of various species hunt nearer the surface and larger catfish such as the American Channel Cat will take a duck or other water bird. So, the modal catfish is a fish that hunts from below, can take large prey, and occasionally eats a bird. The range of size of sampled catfish ranges from 0.9

Raptor migration : More like rapacious bonanza, even those of us who have witnessed the Neotropical River of Raptors nearly fell out of our shoes when treated to several thousand Steppe Buzzards and Black Kites flowing overhead along with a healthy sampling of eagles, harriers, and other birds of prey!
