BirdNote Daily

Every year, hundreds of bird species migrate between North and South America. Some species likely evolved from ancestors that moved north in search of new breeding habitats: the “southern home” hypothesis. But others may have extended their winter ranges south: the “northern home” hypothesis. Many birds have likely gained and lost the ability to migrate multiple times over the course of evolution. And it’s still happening today.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Window collisions kill nearly one billion birds every year in the U.S., with many fatalities occurring during spring and fall migration. Judy Pollock, president of the Chicago Bird Alliance, says this problem has a solution: using bird-safe glass or applying a tight grid of decals to existing windows to make them easier for birds to see.Though many building owners are reluctant to make these much needed changes, Judy and her collaborators are advocating for a city-wide ordinance that would require new construction and major renovations in Chicago to use bird-safe glass.

In the tidal marshes of the East Coast, the Saltmarsh Sparrow has a breeding strategy described by scientists as featuring an “obligate, promiscuous, and bond-free relationship between males and females.” That means both sexes copulate with multiple individuals, without a lasting relationship. The female is singularly responsible for nesting and hatching and drives off males that approach while she is raising her young.More info and transcript at BirdNote.org. Want more BirdNote?

As a young child, Kenn Kaufman ventured into his neighborhood in search of the tigers, bears, and dinosaurs, but quickly found that Indiana doesn’t have those. So he set his sights on the next best thing: figuring out which birds were in his family’s yard. Though he’s now a world renowned birder and field guide author, he says his progress was slow. Today’s novice birders have access to mobile apps and websites that put photos, bird calls, and range maps at your fingertips. But whatever tools you choose, Kenn says there’s no substitute for getting outside and experiencing the birds for yourself.More info and transcript at BirdNote.org. Want more BirdNote?

Because of invasive species and climate change, many of the native birds of Hawai‘i are endangered or have gone extinct. Sam ‘Ohu Gon, Senior Scientist and Cultural Advisor for the Nature Conservancy of Hawai'i, says the bright red bird called the ‘i‘iwi holds a special place in native Hawaiian culture. The bird’s feathers appear as the red color in traditional Hawaiian featherwork. Preserving the bird means preserving the strong cultural relationship with the species.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

As winter approaches, birds like chickadees employ clever strategies to survive the cold. They engage in food caching, hiding seeds for later use. This behavior highlights a fascinating connection between their environment and brain adaptations, particularly the growth of the hippocampus. This enhancement improves their spatial memory, allowing them to locate their hidden treasures even in harsh conditions. Discover how these small avian creatures tackle the challenges of colder climates!

A flock of small shorebirds, like Western Sandpipers, twists and turns, glittering in the sky. When threatened by a falcon, these birds take to the air, flying so close together that it's hard for a predator to capture one. A bird at one edge turns toward the middle, and a wave sweeps across the entire flock in less than a second.More info and transcript at BirdNote.org. Want more BirdNote?

The American Wigeon is a grazer. Its bill is narrow, with a pointed tip like that of a goose. When feeding on water plants, a wigeon grabs a leaf and rips it off with its strong bill, rather than using the straining apparatus typical of dabbling ducks. Take a field trip with your local Audubon and see if you can spot a wigeon.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In the UK for years, milk came in bottles with foil caps. Great Tits, a common songbird, learned how to peck through the foil. The skill spread. But how? Researchers trained Great Tits in different ways of opening a box and re-released them. Knowledge of how to open the box spread rapidly, with most birds copying the trained bird in their group. In a follow-up study, the researchers made one method of opening the box more effective. Many birds quickly switched to the better method, suggesting the tits can stand up to peer pressure if they see there’s a better way of doing things.More info and transcript at BirdNote.org. Want more BirdNote?

Put your winter garden to work as a haven for birds. Leaves and brush left to compost provide foraging and roosting places, smother this year’s weeds, and feed next spring’s plant growth. Watch for juncos and towhees in the leaf litter and wrens in the brush. Maybe even a Song Sparrow! With a little planning, your garden can be a haven for birds year round.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
