What you likely know: The recent contest to select artwork for the 2022–2023 Federal Duck Stamp stirred late night laughs with a satirical painting of a duck hunting a human hunter. What you may not know: The Federal Duck Stamp serves as more than a conservation tool or a cool collector’s item.

If you encounter a nestling or fledgling outside the nest, learn how to assess if the bird is in danger—and whether it's wise to intervene—and if so, what to do.

Soon after nesting season ends, many birds replace their feathers. Songbirds generally lose and regrow a few feathers at a time, so molt is hardly noticeable. But some birds, especially northern cardinals and blue jays, can lose all their head feathers at one time—a catastrophic molt.

To some, sparrows may seem insignificant—a group of mostly small, mostly brown, superficially similar songbirds. Even those of us who love birds may be tempted to brush sparrows off as "little brown jobs." But the truth is that there are several dozen sparrow species in North America alone, and each is unique with something special to offer. As the weather continues to turn colder, many types of sparrows are moving south, showing up in weedy fields, along woodland edges, and at backyard feeders across the country.
