Rose-breasted Cockatoo

Stowaway Cockatoo Takes a Cruise

A beautiful Rose-breasted Cockatoo named Harri took the adventure of a lifetime. She set off unseen on a cruise ship from Brisbane, Australia, and wasn’t discovered until the ship neared New Zealand. Authorities there were not happy to see Harri, whose species is the bane of farmers in her…
Greater Flamingos in the Galapagos

Just What Are Flamingos?

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…
Great Horned Owl perched on railing in urban area

City Owls

Some owls, like Barred Owls and Great Horned Owls, live in the city. As hunters, they find a lot to eat in the city — like rats or squirrels! Both favor urban parks, cemeteries, and botanical gardens — places with big trees — and both roost during the day. The Great Horned Owl, like this…

Ivory Gull and Conservation

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…
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…

Birds of Prey and Nesting Territories

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…
Western Gull

Gull Identification II

The challenge of learning which gull is which brings to mind a crossword puzzle. Take in all the clues, and come up with the right answer. For identifying gulls, we recommend a good bird book, binoculars, perhaps a thermos of hot coffee, and maybe a chair. So which gull is this? Large gull…
Black-capped Chickadee

Chickadee Brains Are Bigger in the Cold

As the colder months arrive, birds that remain in northern climates face the harsh realities of staying warm and finding food. Some birds approach the food problem by storing it in advance — a behavior called caching. Chickadees, nuthatches, jays, and some woodpeckers are known to cache…
Male Peacock faces the viewer, his tail fanned out in display

The Peacock's Tail: More Than Meets the Eye

When a male Indian Peafowl unfurls its magnificently-colored tail and shakes it, it creates an ultra low frequency sound that we humans can’t hear. But it seems to get the special attention of female birds, called peahens.
Eastern Meadowlark perched on a fence post, and singing.

Meadowlarks and Grasslands

The clear, whistled music of the Eastern Meadowlark is the unmistakable anthem of eastern North America's farmlands and open country. The Western Meadowlark and its sweet, liquid notes epitomize the natural expanses of the American West. Sadly, birds of such grassy habitats are among the…
