A house wren can feed 500 spiders

When danger threatens, a turkey vulture defends itself by puking up its last meal. This is a very gross and very effective defense strategy.
More than 70 different bird species have been observed drinking nectar from hummingbird feeders.
Herons and egrets were once shot by the thousands so that their ornate feathers could be used to decorate womens' hats. The shooting of most migratory birds is now illegal.
Hummingbirds beat their wings as fast as 50 times per second, the fastest of any bird on the planet. This speedy wing beat, plus a rotating wrist joint, allows a hummingbird to hover in place, to fly backwards and upside down, and to catch tiny flying insects.

Roadrunners eat almost anything they can catch: lizards and snakes, small rodents, scorpions and tarantulas, and large insects. They'll even leap up to catch hummingbirds at nectar feeders.
Peregrine falcons may reach speeds of 200 miles per hour when diving for prey. They use their balled-up talons to knock out their prey, then catch the hapless, falling bird before it hits the ground or water.
A barn owl can swallow a large rat whole. After digesting its meal, the owl coughs up a pellet containing the rat's bones and fur.
A Baltimore oriole can eat as many as 17 hairy caterpillars in a minute.
