Like a jazz player beating out a drum roll, a woodpecker uses its bill to rap out a brisk series of notes. Early spring resounds with the percussive hammering of woodpeckers. Their rhythmic drumming says to other woodpeckers, "This is my territory!" We also hear them knocking on wood when they carve holes in trees to create nest cavities or reach insects. For any woodpecker, it’s all about proclaiming a signal as far and as loud as possible. Look for Yellow-bellied Sapsuckers in the Northeast and farther north, and Red-breasted Sapsuckers in the West.More info and transcript at BirdNote.org. Want more 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.

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.

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.

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. Sign up for BirdNote+ to get ad-free listening and other perks.

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?
