Great-tailed Grackles live up to their name. The glossy black males trail their long, V-shaped tails behind them as they fly, almost like a plane towing a banner ad. And while not quite as flashy, the brown-feathered females have impressively long tails, too. Also known as the Mexican…

Although a field of grass might not seem like valuable habitat at first, many birds have adapted to nest in grassland habitats and nowhere else. In North America, birds such as the Bobolink seek out grasslands to raise their young, deftly hiding their nests within the dense vegetation…

Throughout winter, Northern Bobwhites gather in groups called coveys to search for food during the day and share warmth at night. These small quail arrange themselves in a circle, with their tails in the center and heads outward, huddled up like a wreath of plump birds to survive frost and…

Common Yellowthroats are one of the most abundant warblers in North America. They’re adaptable birds, thriving in places that pickier warblers pass over. So it’s easy to find yellowthroats in urban areas. Check for them in marshes, overgrown fields, and brushy areas along streams or trails…

Tracking devices revealed that Black Swifts spent over 99% of their time in the air during the winter, almost never touching the ground for months. What’s more, the swifts flew to incredible heights, reaching the highest altitudes on nights when the moon was full – sometimes over 13,000…

Field Sparrows make use of all the warm months of the year by building multiple nests each breeding season. Females will build their first, cup-shaped nest near the ground in dense grasses. As shrubs and trees grow their leaves throughout the summer, they will pick new spots higher off the…

Identifying birds by ear means getting familiar with each species’ unique voice. And that means learning the other voices in the ecosystem, too. Squirrels and chipmunks make calls that can sound a bit like bird calls at times. With practice, each species’ voice becomes more distinct and…

The world is full of poisonous creatures. Some butterflies, beetles and frogs use bright colors to warn birds and other predators that they’re full of toxins. But you might be surprised to learn that some birds are poisonous, too. Birds called Hooded Pitohuis carry toxins produced by a…

Some of the largest populations of Tufted Puffins are in the Aleutian Islands of Alaska and other northern coastlines. But University of Puget Sound professor Peter Hodum says the smaller colonies that breed off the coast of Washington and Oregon could provide key insights to conserve the…
