The American Kestrel is the smallest, most numerous, and most widespread North American falcon. This bird is built for speed, its long pointed wings often bent back at the tip. While hunting, kestrels hover above an open field. These days, the lack of suitable nesting cavities, which…

When a soaring Short-toed Snake-Eagle spots a delicious snake, it swoops down, grabs it with its talons, then tears off the snake’s head. Still on the wing, it swallows the entire snake, head first. Smaller than Bald Eagles, they live mainly in Africa and have legs and toes covered in…

Tennessee Warblers love drinking nectar, but they do it without helping to pollinate flowers. By tapping a hole into the base of a flower, these warblers enjoy an easy meal while bypassing the flower’s pollen. But they give back to their ecosystems in other ways – such as eating countless…

A male Eastern Bluebird stands on a wooden nestbox attached to a fence post. The bluebird’s song – and his alert presence – assert his claim to this territory. In the mid-20th Century, the numbers of bluebirds in the Northeast declined to the lowest level ever, due largely to nesting…

The fluting song of the Wood Thrush is an ethereal sound of summer in North America. During the breeding season, these robin-sized songsters serenade deciduous forests of the eastern U.S. and Canada. Each fall, they migrate to rainforests from southern Mexico to Panama where they call to…

There may be no busier bird during the nesting season than a male House Wren. Just a day or so after completing his spring migration from the tropics, the male House Wren claims a territory and checks out several potential nest cavities. And in each of these locations, he builds a starter…
