Birdnote

During the breeding season, when Eastern Screech-Owls capture the worm-like reptiles known as blind snakes, they deliver them to their chicks alive and wriggling. Some are gulped down immediately, but others escape by burrowing beneath the nest. The surviving “snakes” feed on the insect larvae they find in the nest — larvae that would otherwise parasitize the owl nestlings. A study conducted by Baylor University scientists found that screech-owl chicks grew faster and healthier in nests kept vermin-free by the blind snakes.More info and transcript at BirdNote.org. Want more BirdNote?

An unusual flycatcher called the Great Kiskadee takes on much bigger opponents, sometimes even riding on the back of a falcon for a few seconds to drive them off. Chunky and robin-sized, kiskadees live along wooded edges near water all the way from South Texas to Argentina. They’re a familiar sight around rural towns and villages.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In summer, many shrubs bear fruit that birds find irresistible. Elderberries, serviceberries, blackberries, dogwood berries, mulberries, and currants attract many species of birds, including waxwings, tanagers, robins, warblers and this Rose-breasted Grosbeak. Plants offer this bounty in exchange for birds’ help in distributing their seeds. And in dispersing pollen, birds, bats and insects also help to guarantee a new crop of berries!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Mikko Jimenez is a PhD student doing research on bird migration. Growing up in Chicago, he played beach volleyball at Montrose Beach, a popular spot on the lake shore. At the time, he wasn’t so aware of birds, but as he developed an interest in birding in college, he realized that his old beach volleyball spot was also one of the best places to see birds in the Chicago area.More info and transcript at BirdNote.org. Want more BirdNote?

Sandhill Crane families form a close bond. A pair of adults might travel north with their young from the previous summer, along with grown-up offspring from several years ago. After the breeding season, families will stick together for the journey south and the winter, even in large flocks. The parents often remain together for the rest of their lives.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Some swifts and frigatebirds stay aloft for months. But for a long time, scientists did not know if the birds might be sleeping on the wing. A 2016 study provided answers. Tiny devices attached to the heads of frigatebirds revealed fascinating information: the birds did sleep while aloft, most often one half of the brain at a time. But they also fell into normal, whole-brain sleep and sometimes, even deeper REM sleep. But this deepest sleep came in bursts of just a few seconds — an inflight power-nap.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Midday temperatures in southeast Arizona soar above 100 degrees during the month of July. But relief is coming. A summer monsoon refreshes the Sonoran Desert like a second spring. Grass grows lush, wildflowers spring forth, and birds sing. Cassin’s Sparrows sing their plaintive phrases almost nonstop. Botteri’s Sparrows add their distinctive sputters and trills. And a Rufous-winged Sparrow — like the one pictured here — voices its gentle melody.The sounds heard in this episode were recorded by Gordon Hempton and provided courtesy of QuietPlanet.com.More info and transcript at BirdNote.org. Want more BirdNote?

When they migrate, tiny songbirds that spend most of their lives on land fly hundreds of miles over the ocean at a stretch – and they get tired. A recent study suggests that birds migrating over busy shipping routes in the Mediterranean Sea may use the decks of sea vessels as places to catch their breath when the weather turns bad. More info and transcript at BirdNote.org. Want more BirdNote?

A few times each year, the Eastern Paradise-Whydah puts on its party clothes. This small finch is found in East Africa, and males and females generally share the same nondescript appearance. But when it’s time to mate, the male sprouts extravagant, long, black tail feathers two or three times the length of his body. The feathers make it look like he’s wearing a long black cape, thus the nickname, “the widow bird.”More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Found in much of Central America, White-throated Magpie-Jay flocks are family groups led by a dominant female. They include a mate and several female offspring that bring food to the primary female and her young. It’s an example of cooperative breeding, when birds other than the parents help out to raise young.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Bird nests can be hard to find, often hidden in plain sight. Is the clever camouflage simply the result of using building materials that the birds happen to find? A Scottish research team used birds popular in the pet trade, Zebra Finches, to try and find out. The team gave nesting Zebra Finches two sources of paper to build their nests from: one that matched the papered walls of their cage, and one that did not. By and large, the finches built nests that blended in with their background.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Throughout much of North America, the Great Blue Heron graces waterways, ponds and lakes. They’re built for hunting fish and amphibians along the water — so it might be a surprise to see one stalking across a field, not a drop of water in sight! But sometimes herons leave the water to pursue prey on land, like big insects, frogs, and even small rodents.More info and transcript at BirdNote.org. Want more BirdNote?

Just a few weeks past the solstice, and the real heat of summer is yet to come. Some shorebirds are already on their way south, but most songbirds will be here for a while longer. What's the best time of day to look for them? Many birds are most active in the early morning, taking advantage of the abundance of insects at that hour. Midday heat sends people inside, and birds take a siesta, too. And then, both birds and bugs rev up again in the late afternoon. But hummingbirds and also gulls — including this Glaucous-winged Gull — forage all day long!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Wherever you live, chances are a sweet-singing, cavity-nesting bird would be happy to perform in your yard — and it might stick around if you offer it a cozy nest box, like the one this Carolina Wren enjoys. Natural cavities, like old woodpecker holes, are often in short supply. So putting up a box in the right place — and that’s the right size to accommodate them — is truly an act of stewardship.More info and transcript at BirdNote.org. Want more BirdNote?

During her first year at the Yale School of Architecture, Kenyan graduate student Barbara Nasila was tasked to design a hypothetical outdoor pavilion in a local neighborhood called Dixwell, featuring an original copy of the enslaver John James Audubon’s book, The Birds of America. As Barbara got to know Dixwell, she realized that there was already an existing conversation about birds in the community. She designed an urban oasis with bird habitat and space for community groups — but she left out The Birds of America, feeling that Audubon wouldn’t have cared about this project. More info and transcript at BirdNote.org. Want more BirdNote?

It might sound strange, but dirt helps birds scrub themselves clean. Birds of all sizes (like the Eurasian Skylark seen here) often scrape a depression in the ground and flick dirt onto their bodies, shimmying to shake it off. Experiments showed that birds use dust to prevent oils from building up on their feathers and to remove dandruff — much like humans using shampoo in the shower!More info and transcript at BirdNote.org. Want more BirdNote?

Birds of the same species don’t always sing exactly the same as each other. But those that live near each other sometimes have similar songs. Scientists refer to this pattern as a song neighborhood. It’s less like a regional dialect among people that’s found over a large area. It’s more local than that, like a group of friends copying each other's mannerisms.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Bird feathers are famously light, but they’re also strong, holding up under tricky flying and high winds. They’re made of beta keratin, a tougher version of the keratin that makes up human fingernails and hair. They also have an intricate branching structure that makes them highly flexible and free of unnecessary weight.More info and transcript at BirdNote.org. Want more BirdNote?
