Birdnote

Birds are often admired for their ability to fly. But braking just in time to avoid a crash landing is amazing by itself. How does a robin go from full-out flight to a dead stop at a tree? If we could watch in slow motion, we’d see it raising the angle of its wings higher and higher from the horizontal. A hawk dives a bit below where it wants to perch, then pulls into a steep climb, slowing its momentum. And this female Wood Duck will use a combination of raised wings and a bit of hydroplaning with her wide, webbed feet to land on water.More info and transcript at BirdNote.org. Want more BirdNote?

Identifying birds by ear means getting familiar with each species’ unique voice. And that means learning the other voices in the ecosystem, too. Squirrels and chipmunks make calls that can sound a bit like bird calls at times. With practice, each species’ voice becomes more distinct and familiar.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Rasheena Fountain studied environmental science and worked at her local Audubon Society. Now she writes about nature and diversity in the outdoors. And what got her interested in the first place? It all started in kindergarten, with a teacher named Miss Beak and the first robin of spring.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Alison Vilag has worked for half a decade as a fall and spring waterbird counter at remote migration hotspots around Lake Superior. For weeks, every day from sunrise to nearly sunset, Alison is outside in frigid and volatile weather, identifying species from afar and tallying them with a clicker. Working close to the elements puts Alison face-to-face with the reality of dwindling bird populations.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The world is full of poisonous creatures. Some butterflies, beetles and frogs use bright colors to warn birds and other predators that they’re full of toxins. But you might be surprised to learn that some birds are poisonous, too. Birds called Hooded Pitohuis carry toxins produced by a beetle that they eat, Ruffed Grouse can pick up a poison from a plant called mountain laurel, and Common Quail sometimes snack on poisonous hemlock.More info and transcript at BirdNote.org. Want more BirdNote?

Some of the largest populations of Tufted Puffins are in the Aleutian Islands of Alaska and other northern coastlines. But University of Puget Sound professor Peter Hodum says the smaller colonies that breed off the coast of Washington and Oregon could provide key insights to conserve the whole species. The challenges facing birds at the fringes of their range could be the same ones that will affect the core populations further north in the future.More info and transcript at BirdNote.org. Want more BirdNote?

Weighing about as much as four paperclips, Bushtits are smaller than many hummingbirds. And they take full advantage of their diminutive size. While larger insect-eaters forage on the upper surfaces of leaves, Bushtits hang beneath them, plucking all the tiny insects and spiders hiding out of sight. They pair off to nest. (This male Bushtit is working on his nest.) Where they live in Western suburbia, a flock of Bushtits can help rid a garden of harmful aphids and scale insects. Shun the pesticides and let these guys do the work!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Imagine an Ostrich, an Emu, a roadrunner, and the world’s fastest man and woman, all lined up for a race. Olympic sprinter Usain Bolt holds the men’s record for the 100-meter dash — 28 mph — and Florence Griffith-Joyner ran it just a shade slower. But in this race, Africa’s Ostrich takes gold, crossing the finish line at an incredible 43 mph. The Emu from Australia takes silver, topping 30 mph. The roadrunner comes in last.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

A captive breeding program has helped set California Condors on the path to recovery. But when biologists reviewed the family tree for the breeding program, they found a big surprise. Two chicks had DNA that linked them perfectly to their mothers but didn’t match a single male. They arose through parthenogenesis, developing from unfertilized eggs without sperm from a male. These condors are the first known case of parthenogenesis in a wild bird species where the females had access to fertile males.More info and transcript at BirdNote.org. Want more BirdNote?

The sight and sound of the Bare-throated Bellbird—the national bird of Paraguay—inspires wonder and delight. Its presence as an indicator species and seed disperser also bodes well for ecosystem health in the Alto Paraná Atlantic Forests that stretch from Southeast Brazil through eastern Paraguay and into Northern Argentina. The loud, metallic call of the Bare-throated Bellbird also inspires music played on another emblem of Paraguay—the harp. The species is considered Near Threatened because of loss of forest habitat and poaching for cage birds.More info and transcript at BirdNote.org. Want more BirdNote?

When biologist Danielle Whittaker started studying bird odors, some scientists tried to discourage her, claiming that birds can’t smell. But that only deepened her curiosity. Once, she caught a whiff of a cowbird, which smelled to her like sugar cookies. Danielle and her colleagues studied Dark-eyed Juncos and found that they produce many odors that help influence breeding behavior.

Shortly after the Russian invasion of Ukraine in February of 2022, zookeepers at the Kyiv Zoo shared audio recordings from the animal enclosures with BirdNote. The Zoo staff maintained care for the animals even as they slept in bomb shelters. Two and a half years later, Zoo Program Manager Olga Baratynska shares new audio of animals at the zoo and a report on their animal therapy program, called “The Good Phasmatidae,” which has treated nearly 200,000 people, including children, displaced people, and members of the military.More info and transcript at BirdNote.org. Want more BirdNote?

Kingbirds are robin-sized flycatchers that excel at plucking insects from the air. They’ll even tackle prey as big as cicadas. Finding naturally-camouflaged cicadas hidden among the leaves is hard work. But two species of kingbirds in Arizona found a shortcut — stealing them from cicada-killer wasps! The female wasps, nearly two inches long, paralyze cicadas and bring them to their burrows for their young to eat. The kingbirds have learned to ambush wasps carrying cicadas on the way back to their burrows.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The glorious song of the male Sage Thrasher rings out every Spring from tracts of sagebrush throughout the west. Sagebrush was once widespread in the Great Basin region, and so were the thrashers. But huge areas of sagebrush were turned into alfalfa and potato farms, and the songs of the thrasher aren't so common today. Sagebrush badly needs advocacy. The Important Bird Areas program works to protect key habitats for birds.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

House Finches are familiar birds all across North America. Researchers have shown that the red coloration of males is produced from carotenoid pigments in the birds' diet. Male House Finches develop brighter plumage when they are growing in new feathers, if they eat more fruits containing carotenoids. Females prefer more brightly colored males. Redder males also attract females in better condition, and such a pair raises, on the average, more young. You can learn more at AAAS.org.More info and transcript at BirdNote.org. Want more BirdNote?

A Laysan Albatross named Wisdom has been nesting and raising chicks on the island of Midway for nearly 60 years. She was banded back in 1956 and was rediscovered, still alive and healthy, in 2002. Since that time, scientists have watched Wisdom closely. Every year, she has managed to navigate the many perils facing her species and successfully raise a new chick.More info and transcript at BirdNote.org. Want more BirdNote?

Tree Swallows and bluebirds — like this Western Bluebird — are among the earliest northbound migrants to arrive, heralding spring a month before the equinox. These species will nest only in cavities, such as old woodpecker holes or man-made nest boxes. But the supply of specialized nest sites is limited, and competition is intense. By arriving early, these swallows and bluebirds improve their chances of securing unoccupied cavities.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

During winter and early spring, Great Blue Herons build their nests high in the treetops. The male delivers the supplies to the nest site stick by stick, as the female arranges things. It’s the perfect childhood home for their young, made without blueprints, architects or engineers. But by early May, the chicks are starting to test the limits of their nests!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Upland Sandpipers are an emblematic bird of grassland habitats in many regions of the Americas. These shorebirds live far from sea with the largest breeding populations in the north central U.S. But Upland Sandpipers are losing breeding ground to row-crop agriculture, pushing some birds to nest at airports as a substitute for natural prairies. Preserving grasslands throughout their range will help ensure that the Upland Sandpiper’s signature whistling song continues to ring out.This episode is sponsored in memoriam of Alice Ashbaugh, a lifelong birdwatcher and amateur ornithologist.More info and transcript at BirdNote.org. Want more BirdNote?
