An App That Helps You Hear High-Pitched Bird Songs

BirdNote Daily ·

2024/03/01

For years, nature recordist Lang Elliott came up with clever ways to hear high-pitched bird songs despite his high-frequency hearing loss. Lang teamed up with a programmer to develop an app called Hear Birds Again. Currently it’s only available for iPhones, but it’s able to take high-pitch bird songs and shift them down into a lower range.More info and transcript at BirdNote.org. Want more BirdNote?

How Noise Pollution Affects Birds

BirdNote Daily ·

2024/02/28

Dr. Clinton Francis is a sensory ecologist who studies how noise pollution affects birds, like this Black-headed Grosbeak. He says sounds from machines and vehicles can really disrupt bird behavior. Although birds rely on hearing to sense predators and prey, and to find mates, their sense of hearing isn’t very good, making them very sensitive to noise pollution from machines and vehicles. Fortunately, there are many ways to help birds by reducing noise pollution.More info and transcript at

2024/02/27

When Day Scott teaches people how to take pictures of birds, she emphasizes observing birds carefully before picking up the camera. Sometimes that means choosing whether or not to even attempt a photo. In this episode, Day shares a story about choosing whether or not to try and photograph a rare Painted Bunting in her area or to see the bird in high-definition through her binoculars.More info and transcript at BirdNote.org.

Birds, Berries and Germination

BirdNote Daily ·

2024/02/26

Some plants have evolved fruits with edible flesh that attract birds. When birds swallow the fruit, they also ingest the seeds. They transport the seeds to new spots for the plants to take root. Birds’ digestive systems grind away the hard outer coating of the seed, making it more likely to germinate. Seeds in a bird’s droppings are pre-packaged in nutrient-rich fertilizer.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Hovering Is Hard Work

BirdNote Daily ·

2024/02/25

Hummingbirds are built for hovering flight, with flexible wrists that rotate their wings in a rapid figure-eight motion that generates almost constant lift. Eurasian Skylarks, on the other hand, hovers by fluttering its wings 10-12 times per second, singing all the while. Some raptors such as American Kestrels use a different strategy: by flying into the wind, they can float in place while they scan for prey.More info and transcript at BirdNote.org.

Biomimicry - Japanese Trains Mimic Kingfisher

BirdNote Daily ·

2024/02/24

In the 1990s, train engineers in Japan built trains able to travel nearly 170 miles per hour. The problem was that when the trains exited a tunnel, the air in front of their bullet-shaped noses expanded rapidly, creating a loud “tunnel boom.” The chief engineer, a birder, looked to the shape of a kingfisher’s bill to design long, narrow train noses that parted the air. The trains became both quieter and more efficient.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our

Dining with Sanderlings

BirdNote Daily ·

2024/02/23

While many shorebirds have gone south, tiny sandpipers called Sanderlings are easy to find on winter shores. They follow the waves as they lap in and out, probing the swirling sand for prey. They often eat various small crustaceans such as mole crabs, isopods, and amphipods. But they also enjoy miniature clams, polychaete worms, and horseshoe crab eggs. They’ll even catch flying insects or eat plant matter.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly

Creating Abstract Paintings of Migratory Birds

BirdNote Daily ·

2024/02/22

Artist Debra Ramsay became fascinated with the way that birds and their colors mark changes in the seasons. In her “Migrations” project, she painted species seen in New York’s Central Park, creating an abstract design from the three main colors of each bird. Debra layered colors into thick plexiglass panels, so the paintings appear to change when seen from different angles.More info and transcript at BirdNote.org. Want more BirdNote?

Tennessee Warbler, Nectar Thief

BirdNote Daily ·

2024/02/21

Tennessee Warblers love drinking nectar, but they do it without helping to pollinate flowers. By tapping a hole into the base of a flower, these warblers enjoy an easy meal while bypassing the flower’s pollen. But they give back to their ecosystems in other ways – such as eating countless insects!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Lesser Yellowlegs, Loud and Proud

BirdNote Daily ·

2024/02/20

When the shorebirds called Lesser Yellowlegs sense a threat to their nest, they’ll put up an unforgettable racket to drive the danger away. Smaller and with a shorter bill than the Greater Yellowlegs, Lesser Yellowlegs sing to attract mates, while flying or perching up in a tree like a songbird. Although they’re widespread, Lesser Yellowlegs have lost over half their numbers in the last 50 years. Protecting wetlands, addressing climate change, and using sustainable farming practices can all help

Nictitating Membranes - Nature's Goggles

BirdNote Daily ·

2024/02/19

For most birds, keen eyesight is critical for survival. But many birds lead lives that can be very hard on the eyes — like flying at breakneck speed, racing for cover into a dense thicket, or diving under water to capture prey. Imagine how the chips fly as this Pileated Woodpecker chisels a cavity. Fortunately, birds have evolved a structure for protecting their eyes. Beneath the outer eyelids lies an extra eyelid, called the nictitating membrane. It helps keep the eye moist and clean while guarding

Finding Food When it Snows

BirdNote Daily ·

2024/02/18

Fresh-fallen snow is beautiful, but it poses a challenge to birds. The ground where they found food is now covered by several inches of snow. Birds such as juncos and other sparrows flit under bushes where snow doesn’t cover the ground. Finches and chickadees pick at the seed heads of plants sticking out above the snow, while robins (like this American Robin) seek out dried fruits. Nuthatches and woodpeckers cling to trees as they search for insects within the bark.More info and transcript at

Costa Rica Winter Sunrise

2024/02/17

On a winter morning in Costa Rica, a colorful choir welcomes the day. A pair of Bay Wrens sings a brisk duet just before sunrise. Perched in the upper canopy of the tropical lowland forest, a group of Keel-billed Toucans calls out. In a nearby tree, Purple-throated Fruitcrows (like this one) add their voices to the chorus. Then a male Montezuma Oropendola belts out an electrifying series of notes — one of the most distinctive voices in the tropics. Finally, a Bright-rumped Attila calls from its

Cockatoos and People Trying to Outwit Each Other

BirdNote Daily ·

2024/02/16

In several neighborhoods of Sydney, Sulphur-crested Cockatoos have learned ways to open trash bins and grab some leftover food. Researchers found that birds in a given suburb seem to learn their trash bin opening technique from nearby birds, leading to subtle differences in how cockatoos raid the garbage throughout the city. This has pitted two highly intelligent species against each other as people have tried to come up with deterrence methods to keep birds away from the trash.More info and

2024/02/15

Sam ‘Ohu Gon was one of the last people to see an ‘Ō‘ū, a native Hawaiian bird that’s presumed to be extinct. He’s worked at the Nature Conservancy of Hawai‘i for nearly forty years. In 1988, he took part in an Audubon Christmas Bird Count, hoping to encounter critically endangered native birds.More info and transcript at BirdNote.org. Want more BirdNote?

Tokens of Affection

BirdNote Daily ·

2024/02/14

Birds have many ways of showing affection for their partners. One way is allopreening, where a bird uses its bill to groom a mate, twirling each individual feather in its beak (like these Macaws). Other birds present their partners with gifts like moss or sticks. A female Arabian Babbler might reciprocate with a gift of her own — or just cut to the chase and lead her suitor to a rendezvous spot in the shrubbery.More info and transcript at BirdNote.org.

Rainbow-Billed Toucan: The Flying Banana

2024/02/13

The Keel-billed Toucan, also known as the Rainbow-billed Toucan, looks like a bird with a giant banana for a beak. They have a black body, a yellow patch from the face to the breast, and a huge rainbow-colored bill. The big beaks have more than one use: they can be used for fighting with rivals, but they can also help toucans regulate their body temperature in the tropical heat.More info and transcript at BirdNote.org.

Telling Apart Two Cheery Bird Songs

BirdNote Daily ·

2024/02/12

The American Robin and the Baltimore Oriole both have cheery, upbeat songs. At first, you might think there’s no way to tell these two cheery, upbeat singers apart. But there are a couple of differences. American Robins usually have a longer song, while Baltimore Orioles usually stop after a phrase or two. Plus, Baltimore Orioles sound sweeter and more melodic than American Robins, who can come across a little screechy at times.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe

When the bitter cold of winter arrives, songbirds face an emergency: how to keep warm through the night. On normal nights, many prefer sleeping solo in a sheltered spot. But in severe cold, some kinds of birds may have a greater prospect of survival by roosting with others.More info and transcript at BirdNote.org. Want more BirdNote?
