Northern Pygmy Owl, showing "eyes" on back of head

Pygmy-Owls' False Eyes

This Northern Pygmy-Owl appears to have eyes in the back of its head. But why? One theory is that large false eyes may create the illusion that the owl is much bigger than its 6 and 3/4-inch size. A more current theory is that the false eyes help protect the pygmy-owl's true eyes. Small

Little Brown Birds

So many little brown birds look the same. They might be sparrows, or wrens, or finches, or something altogether different. And you often find them together in winter. Learning to tell these "LBBs" apart can be really frustrating for novice birdwatchers. Birds such as wrens, finches, and

Puffin with fish in its beak

All Those Fish in a Puffin's Beak

Puffins fly under water into schools of slender fish, filling their large beaks. Fish are wedged into the gape, the stretchy skin at the beak hinge, but the bill edges still line up neatly. The dangling fish won’t slide out because the puffin’s tongue and roof of the mouth are heavily
Flock of Western Sandpipers

Chorus Line in the Sky

A flock of small shorebirds (like these Western Sandpipers) twists and turns, glittering in the sky. When threatened by a falcon, these birds take to the air, flying so close together that it's hard for a predator to capture one. A bird at one edge turns toward the middle, and a wave
