Chickadees are tiny songbirds named for their characteristic song and there are seven species found in North America. You'll find the Black-capped Chickadee across the northern U.S. into Canada. The Carolina Chickadee holds sway in the Southeast. Hear the husky voice of a Mountain Chickadee in the Rockies. Travel to Canada for the Boreal Chickadee. This Chestnut-backed Chickadee calls the Pacific...

Sapsuckers drill small holes in the bark of favored trees, then return again and again to eat the sap that flows out. And hummingbirds, kinglets, and warblers come to the sap wells to eat the insects trapped in the sap. Although a sapsucker (like this Red-breasted Sapsucker) may suck a tree's blood, so to speak, the drilling usually doesn't damage an otherwise healthy tree.More info and...

The library relies on both professional field recordists and dedicated volunteers to capture the sounds of birds all over the world.Support for BirdNote is provided by Marjorie and Ed Ringness from Seattle, Washington —...

Before the high-tech gadgets used to track bird migration today, there was moon-watching: a technique dreamed up in the 1940s by ornithologist George Lowery. Using telescopes pointed at the moon to see the silhouettes of migratory birds, Lowery helped show that birds regularly migrate across the Gulf of Mexico and organized the first continent-wide survey of migration in North America.

Corvids, like crows and jays, are known for caching seeds instead of eating them immediately. Sometimes, those seeds take root before the birds return. Mario Pesendorfer, a forest and behavioral ecologist at BOKU in Vienna, says that’s what happened on Santa Cruz Island in southern California. It’s part of Channel Islands National Park where native shrub oak habitats were largely decimated by...

The stars appear to rotate in the sky, raising the question of how birds can use stars to navigate during migration. Ornithologist Stephen Emlen brought Indigo Buntings to a planetarium, tracking their movements as the simulated night sky changed above them. The buntings oriented themselves using star patterns that appear to rotate the least — especially the North Star, Ursa Major and...

Today is the Autumnal Equinox, when the sun crosses the equator and day and night are of approximately equal length across the globe. In her poem ‘Utsuroi’, writer Lee Ann Roripaugh reflects on how, as the days grow shorter, the remaining light feels that much more beautiful.More info and transcript at BirdNote.org.Want more BirdNote?

Nature educator Johanne Ryan shares her observations of Southern Lapwings, shorebirds that make their nests on the ground in open areas and vigorously defend them. If a potential predator approaches, the parent will sound a piercing alarm call. If that doesn’t work, the lapwing will charge the opponent, using a secret weapon – sharp, bony spurs on the bird’s “wrists.”More info and transcript at...

Author Kira Jane Buxton loves crows — so much that she’s written two novels about a crow named S.T. navigating the extinction of humanity. When she was writing those books, she tried befriending the crows in her neighborhood and wound up bonding with a pair of them. She named them T and Dart. T, the female, is clumsy and playful. Dart, her mate, is more aloof towards Kira but always shares his...

Williamson's Sapsuckers nest in western mountain forests. The radically different plumages of the male and female so confounded 19th-century naturalists that, for nearly a decade, the birds were thought to be of different species. Sapsuckers are unique among woodpeckers in drilling neat rows of tiny holes — or sapwells — in the trunks of trees. The sap provides food for the sapsuckers and snags...
