Most birds possess the ability to see color. But birds can also see in the ultraviolet spectrum! Hummingbirds — like this Violet-crowned Hummingbird — may zero in on certain flowers because their petals strongly reflect in the ultraviolet range. Migrating birds may use ultraviolet light to navigate on overcast days, because the sun's ultraviolet rays pass through the cloud cover.This episode is sponsored by Bird Conservancy of the Rockies.

Found in Australian forests, male Superb Lyrebirds can mimic calls well enough to convince the bird they’re imitating that the lyrebird is one of their own! While males sing to attract mates, females imitate the calls of predators, which could help frighten other birds off their territories.Listen to this episode in Spanish here.More info and transcript at BirdNote.org.Want more BirdNote?

National Battlefield Parks are grassland habitats worth writing home about. Tall grassy fields aren’t typically considered beautiful, much less valuable to conserve. But battlefield monuments and military parks are maintained as historic sites, with the side-effect of preserving excellent habitat. Today, rather than the roar of cannons, battlefields like Gettysburg, Antietam, and Monocacy are filled with the sounds of grassland songbirds.More info and transcript at BirdNote.org.Want more BirdNote?

Brooklyn’s Prospect Park covers more than 500 acres — many of them covered in trees. One bird species that calls the park home is the strikingly beautiful Blue Jay, which nests, forages, and roosts in trees. In the eastern U.S., you can invite Blue Jays into a small yard with just a decent tree or two. It’s the volume of branches and leafy habitat overhead that matter to the jays.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

If you’re trying to spot a bird, you should look up — right? While it’s true that there are many beautiful birds to see in the sky, plenty of species are easier to find by keeping your eyes and ears to the ground. You may encounter towhees using their powerful feet to kick up leaf litter beneath dense underbrush. American Pipits and small shorebirds often look like clods of mud before they start running across a roadside field. There are even some colorful warblers who prefer to skulk!More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

The Steller's Jay is a jay... and it's blue. But it's not a true Blue Jay with a capital "B." The bona fide Blue Jay is primarily a bird of eastern North America. Blue Jays and the Steller's Jays have similarly raucous personalities. Like their larger cousins, the crows, ravens, and magpies, they are intelligent opportunists.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

At the close of a summer day, the songbirds go silent. As if on cue, the birds of the night make their voices known. In an Eastern woodland, the eerie trills and whinnies of an Eastern Screech-Owl are among the first sounds of the night. Meanwhile, as night falls west of the Rockies, a Western Screech-Owl calls out. But there’s another bird whose voice will drown out the loudest of screech-owls: the Barred Owl! Pairs may break into a rollicking duet, sometimes called their “monkey call.”More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

The Ross’s Gull is a dainty seabird that’s rarely found south of the High Arctic. Though their bodies are mostly gray, their breast feathers and underparts glow a satiny pink thanks to pigments from the marine crustaceans they pluck from the ocean’s surface. Every so often, a Ross’s Gull drifts into southern Canada and the U.S. — and almost always attracts an adoring crowd.More info and transcript at BirdNote.org.Want more BirdNote?

By August, many birds have just completed the intense rigors of nesting and raising young and now undergo a complete molt. Molt is a cyclic process of feather growth. As new feathers grow in, they push the old ones out. Why molt? Because feathers wear out. Songbirds that migrate long distances need to complete this process on a tight schedule, to be ready when it's time to strike out in September. You might not even recognize this American Goldfinch in its winter plumage.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

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 improve habitats for birds by planting native fruit bushes and advocating for wildlife-friendly gardening in public green spaces.Support for this episode was provided by Jerry Tone and Martha Wyckoff from Seattle, Washington — and generous listeners around the world.More info and transcript at BirdNote.org.Want more BirdNote?
