White-breasted Nuthatches aren’t the toughest birds on the block — but when it comes to their nests, they know how to put up defenses. Squirrels could easily duck inside a nest cavity and gobble up the eggs. That’s why you might see nuthatches sweeping around their nest hole with a beetle or other

White-breasted Nuthatches aren’t the toughest birds on the block — but when it comes to their nests, they know how to put up defenses. Squirrels could easily duck inside a nest cavity and gobble up the eggs. That’s why you might see nuthatches sweeping around their nest hole with a beetle or other insect.

On a still winter afternoon, you may hear Common Goldeneyes flying low across the water. Whistlers, their wings sibilant, make the sound – as Ernest Hemingway wrote – of ripping silk. Common Goldeneyes nest in cavities, in northern boreal forests.

Few birds are as distinctive as flamingos. Scientists once grouped flamingos with storks and ibises. But a study of flamingo DNA delivered a stunning surprise: their closest living relatives appear to be grebes. And an even bigger surprise: DNA indicates that flamingos and grebes share an ancestry

Few birds are as distinctive as flamingos. Scientists once grouped flamingos with storks and ibises. But a study of flamingo DNA delivered a stunning surprise: their closest living relatives appear to be grebes. And an even bigger surprise: DNA indicates that flamingos and grebes share an ancestry with certain land birds, like doves. So flamingos e…

Polar Bears symbolize the icy landscapes of the far north like no other animal. The bear's way of life — its very survival — is inseparable from the Arctic pack-ice. Less familiar is a remarkable bird that shares with the Polar Bear this vital link to ice: this Ivory Gull. The gulls feed on small fish and other marine life, but also scavenge carcas…

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 birds will

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 birds will mob this diurnal owl, even striking it, directing s…

Northern Cardinals are known for their iconic red feathers, yet that scarlet hue is actually derived from yellow pigments in their food. Most cardinals’ bodies transform those yellow pigments into their signature shade of red, but some lack this ability — resulting in a bright yellow bird. House

Red-tailed Hawks typically have a nesting territory of about a half-mile to a full square mile, depending on how much food there is. Bald Eagles’ nesting territories range from 2½ square miles to as much as 15 square miles, for the same reason. But the Gyrfalcons in Finland and Scandinavia really

Everybody’s heard of a gaggle of geese and a covey of quail. But what’s a group of penguins called? And a “conspiracy” of ravens? Maybe the way we label birds says more about us than it does about them.
