How Jays Helped Restore an Oak Forest

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 grazing livestock. After these animals were removed in the 80s and 90s, Santa Cruz Island regained vegetation faster than its neighbors — thanks to seed-dispersing Island Scrub-Jays! It’s just one example of how birds could help restoration ecologists regrow forests around the world. Learn more about restoration ecology in the latest season of Bring Birds Back!

Migrations: Indigo Bunting, Master Stargazer

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 Cassiopeia. More info and transcript at BirdNote.org.

Lee Ann Roripaugh: Utsuroi

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.

Southern Lapwings Defend Their Nest

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 BirdNote.org. Want more BirdNote?

T and Dart

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 food with T. This crow couple helped inspire the fictional crows in Kira’s books. More info and transcript at BirdNote.org.

Williamson's Sapsucker

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 small insects that are eaten by hummingbirds and warblers. More info and transcript at BirdNote.org. Want more BirdNote?

A Lost Hummingbird is Found Again

The Santa Marta Sabrewing is a hummingbird species so rare, they’ve only been documented twice in recent years. Native to the mountains of Colombia, they were officially described in 1946. No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to find them. Then in 2022, Yurgen Vega was studying the birds of a mountain range called the Sierra Nevada de Santa Marta. He snapped a photo of an unusual, large hummingbird – and the sabrewing was lost no more. BirdNote is grateful to former board member and photographer extraordinaire Owen Deutsch and his wife Rona Talcott for their strong support over the years. More info and transcript at BirdNote.org.

Thick-billed Euphonia – Deceitful Mimic

Northern Mockingbirds can learn to mimic the sounds of just about any bird. They mimic to show off, not to deceive. But this Thick-billed Euphonia, a tiny songbird in South America, employs what scientists call “deceitful mimicry.” When frightened by a predator near its nest, a Thick-billed Euphonia imitates the alarm calls of other birds nesting nearby. This stirs them into action as they rush in to harass the predator. The euphonia, meanwhile, sits tight while others do the dirty work. ¡Escuche este episodio en español aquí!

Bicknell's Thrush

The Bicknell’s Thrush is known for scarcity… and promiscuity. Unlike most songbirds, the female thrush establishes a territory and then mates with males that happen by. She then lays eggs that have been fertilized by multiple different males. Many of those males will stick around and help feed the young, even if they are not their own. Each year, these little songbirds make the long journey from the Caribbean Islands to the forests of the northeastern coasts of North America. Support for BirdNote is provided by Sarah Merner and Craig McKibben from Seattle, Washington — and generous listeners around the world. More info and transcript at BirdNote.org. Want more BirdNote?

Where Birds Sleep

All birds need to sleep — or at least snooze — sometime during each 24-hour period. And most sleep at night. A bird, like a Mallard Duckling, may turn its head around and warm its beak under its shoulder-feathers. Songbirds find a protected perch, sheltered from rain and nighttime predators. Small forest birds often spend the night in tree cavities. Ducks sleep while floating in protected bays. More info and transcript at BirdNote.org. Want more BirdNote?
