Las plumas de las aves son conocidas por su ligereza, pero también son sorprendentemente resistentes: soportan vuelos complicados y vientos fuertes. Están hechas de beta-queratina, una versión más resistente de la queratina que compone nuestras uñas y cabello. Además, tienen una estructura…

eBird, a project of the Cornell Lab of Ornithology, lets you log the bird species you observe on a smartphone app or on the web. Whether you’re going on a birding trip or enjoying birds near home, you can list the species you found on eBird. Millions of people all over the world help eBird…

Over the course of four days in February, the Great Backyard Bird Count gathers heaps of info about birds all over the world — and helps people connect with their local birds. Anyone can participate with the Merlin Bird ID app. And if you’re familiar with your neighborhood birds, you can…

Organized by the Cornell Lab of Ornithology, Project NestWatch is made up of volunteers around the world who monitor bird nests, reporting whether the birds successfully raise their young. Joining the project involves a bit of online training, finding a nearby bird nest, and briefly…

In temperate climates like North America, it’s often male songbirds that sing the most. Typically the males migrate north before females and establish territories for the short breeding season, using their songs as a way to claim a spot. But many female birds do sing, even in colder…

While many birds have hollow bones that make flying a breeze, diving birds are built differently. The bones of divers such as Common Loons are denser than those of songbirds and other expert fliers. With a lightweight skeleton, they’d be too buoyant to dive and chase fish. Instead, loons…

The call of the Common Loon is a symbol of the far north. But the species once nested as far south as southern New England, Ohio, Iowa, and California. Human activity and changes to the landscape in these more populated areas has made it harder for loons to persist. There have been…

Like an expert angler, a tern can read the surface of the water to find where to catch its next fish. Scientists piloted a drone to track the flight paths of terns on the hunt. The terns sought out turbulent water. A vortex formed by colliding currents traps fish near the surface, where…

The songs of two common finches provide a steady soundtrack in cities across North America: the House Finch and the American Goldfinch. While they can sound similar, a couple of key features help set them apart. House Finches sing sweetly but often have a sharp, buzzy note near the end…

For folks looking to try birding for the first time, getting started can be daunting. Should you learn every species’ call, every subtle feather pattern before you head out to look for birds? While it’s good to prepare, there’s a risk of scaring yourself out of starting, and preventing the…
