You Are What You Eat

House Finches are familiar birds all across North America. Researchers have shown that the red coloration of males is produced from carotenoid pigments in the birds' diet. Male House Finches develop brighter plumage when they are growing in new feathers, if they eat more fruits containing…

San Diego Bay in Winter

Birds (including Western Gulls, like this one) and people share San Diego Bay -- a deep-water port, navy ships, pleasure boats, and salt-evaporation ponds. Even so, it’s one of the best bird habitats on the West Coast. Western Sandpipers probe the mud for worms and snails. Egrets stalk the…

Three Kingfishers

The Belted Kingfisher is the one species of kingfisher found throughout most of North America north of Mexico. You'll have to go to Texas to see two other kingfishers. The quiet call of the Green Kingfisher - like this one - can be heard at wooded streams and ponds. A Ringed Kingfisher…
Chestnut-backed Chickadee

Why Do Chickadees Come and Go?

A chickadee comes in to the feeder, quickly grabs a seed, and flies away. It may return immediately, but it's more likely to wait its turn. When a whole flock of chickadees moves into the yard, it looks as if they form a living conveyer belt. One chickadee after another flies to the feeder…
Arctic Tern

Why Arctic Terns Have Short Beaks

The bill and legs of Arctic Terns are shorter than those of Common Terns. Because Arctic Terns breed in the Arctic and winter in the Antarctic, they are subject to much colder weather than are Common Terns. Birds' bills and legs lose heat, because they're not covered by feathers. Birds in…
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…
White-browed Coucal

White-browed Coucal

This White-browed Coucal - also known as Burchell's Coucal - is common in many parts of Africa. "Streaky and sneaky" best describes these birds, because you'll be lucky if you see one. Dew from their dense habitat often dampens their feathers. Then, they hop to the top of a bush and spread…

Cattle Egret - You've Got a Friend in Me

Many birds that forage in open country, such as Cattle Egrets, benefit from association with large grazing mammals. The mammals scare up insects as they move, making them more visible to the birds. In the egrets’ native lands in Africa, the birds feed with elephants, rhinos, and Cape…
Brown Thrasher

Shelterbelts and Their Birds

Many species of birds nest in shelterbelts — also known as windbreaks — parallel rows of trees and shrubs planted to shelter houses, farms, and livestock from strong winds and drifting snow. Because shelterbelts often provide more food and lack the predators found in woodlands, they are…
Greater Yellowlegs

Shorebirds Watch Their Feet

Greater Yellowlegs — not surprisingly — have bright yellow legs and feet. And why? While foraging through shallow water, a yellowlegs (like this one) can keep track of its legs by the color, which contrasts with the sometimes dark and irregular bottom. A Sanderling, on the other hand, has…
