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…

Every spring in Northwest Ohio, the shores of Lake Erie transform into a birder’s paradise. Birder and author Kenn Kaufman, who lives in this area, says that of the many species that migrate through here, one group of vibrant, vivacious songbirds stands out from the rest: warblers. Trees…

Many bird species can eat the fruits of plants that are toxic to humans —even the white berries found on poison ivy. These birds just aren’t sensitive to the compounds in the berries that are irritating or poisonous to people. While you probably want to stay away from poison ivy, you can…

For many species of birds, scientists know more about the males than the females. And that’s a problem when making a conservation plan for a species that maps out which habitats to protect. Joanna Wu, a PhD student at UCLA, says that in some species of warblers, males and females live in…

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and…

In the late 19 th and early 20 th centuries, the human fascination with bird feathers went a little too far. Women’s hats and dresses featured extravagant feathers from birds both near and far. The trade in feathers drove several species, from the Little Egret to the Great Crested Grebe…

With their excellent sense of smell, pigs are renowned for sniffing out truffles, a fungus that grows underground and is prized for its taste. But it turns out that some bird species can also find their way to a truffle treat. Researchers working in the Patagonia region of Chile had…

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird…

Many shorebirds breed in the Arctic tundra. It’s such an important ecosystem that every year, the National Oceanic and Atmospheric Administration issues an Arctic Report Card that details how the region has been affected by rising global temperatures. Over the last ten years, satellite…

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the…
