BirdNote Daily

This week is Clean Beach Week. Many busy beaches are also where declining species such as Piping Plovers and Least Terns have their nests. Keeping litter off the shore helps make sure that birds don’t pick up plastic and other waste and try to feed it to their young. Staying out of dunes and marked-off areas where birds are known to nest ensures that people can share the beach with birds and their young for years to come.More info and transcript at BirdNote.org. Want more BirdNote?

There’s a group of birds that lay their eggs underground — in geothermally heated burrows, or  warm sands, or even mounds of organic material warmed by the heat of decomposition. These megapodes or mound-builders — like this Australian Brushturkey — are found in Australia, New Guinea, and nearby islands. The male builds a mound and adjusts the amount of material to maintain a constant temperature. After a long incubation, the eggs hatch and the chicks claw their way to the surface. They never know their parents, but emerge fully feathered and capable of flying and feeding themselves.More info and transcript at BirdNote.org. Want more BirdNote?

While nearly a third of North American bird species are in decline, many birds that depend on wetlands are thriving. Duck breeding populations in 2009 were an estimated 25% above historical averages. Conditions on the breeding grounds have improved since the drought years of the 1980s, but human action has also made a huge difference. You can help by purchasing a duck stamp every year. Adam Grimm's painting of a pair of Canvasbacks won the contest for the 2014-2015 duck stamp.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Noticeably smaller than Mallards, Blue-winged Teal wings have large patches of powder blue edged in emerald. Blue-winged Teal are long-distance migrants, traveling from nesting areas in Canada and the U.S. to South America for the winter. They feed in shallow water with a preference for snails and fly larvae. In fall and winter they seek out plant matter, especially seeds.More info and transcript at BirdNote.org. Want more BirdNote?

Peer into the world of birds, and eyes of many different colors peer back. While eye color isn’t tied to one group of birds or another, a common pattern is a change in eye color as immature birds grow to adulthood. Bald Eagles, Ring-billed Gulls, and ducks such as goldeneyes and scaup have brown eyes as youngsters, and yellow eyes as adults. Red-tailed Hawks reverse this pattern, with their eyes changing from yellow to brown. And the yellow eyes of a young Cooper’s Hawk, pictured here on the right, turn deep red as they reach maturity.More info and transcript at BirdNote.org. Want more BirdNote?

As a kid in Columbus, Ohio, Dudley Edmondson came to love being outside, despite having few outdoor role models who looked like him. As he progressed in his career as a nature photographer in Minnesota, Dudley wanted to show the next generation of Black nature enthusiasts that there are people who look like them in the outdoors. So he wrote a book called Black & Brown Faces in America's Wild Places.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In spring and summer, Yellow Warblers sing from treetops to stream sides. While their beauty and songs commonly light up our most vibrant months, they face imminent challenges. Yellow Warbler populations have adapted genetically to their local climates. That makes them vulnerable to environmental shifts, which could cause the species to lose much of its breeding range in the U.S. by 2080.More info and transcript at BirdNote.org. Want more BirdNote?

Tree Swallows glisten in the June sunlight, as they swoop and glide, their arcs interlacing in the air. When a white feather flutters down among them, one swallow snatches the feather in its bill and flies upward, as another gives chase. After a moment, the lead bird lets loose the feather, which drifts lazily, until the second bird swoops to catch it in midair. Loose feathers are important for Tree Swallows. They line their nests thickly with them.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

When nesting, most birds lay a predictable number of eggs. Bald Eagles: 2. Bluebirds: 4 to 6. Mallards: 10 to 12. But how do they determine when they have laid the right number? To find out, scientists experimented by going to nests and repeatedly removing eggs soon after they were laid. Some birds replaced them straight away. For example, a House Sparrow laid 50 eggs in a row, while a flicker laid 71 eggs in 73 days. But for other birds, the scientists’ removal of the eggs had no effect at all.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

What is it that draws us to a romantic partner? Birds have lots of ways to catch the attention of a mate. Most cranes duet with prospective partners for years before they begin breeding. Crested Auklets of both sexes produce a pungent citrus perfume. And Blue-footed Boobies dance, showing off their feet to each other.More info and transcript at BirdNote.org. Want more BirdNote?
