It’s spring, and a female duck swims across a pond with ducklings in tow. Some of the youngsters might not be her own. Wood Ducks and others may lay some of their eggs in other ducks’ nests — or in the nests of other kinds of ducks, like Common Mergansers and goldeneyes. Biologists call this nest parasitism or egg dumping . Perhaps it’s a kind of insurance against the loss of a nesting female’s own eggs or brood. Hooded Mergansers, like this one, are frequent recipients of eggs from other specie...

Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds, the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that passes through it. By contrast, a human creates sound using only 2% of the air exhaled through the larynx. Birds whose syrinx is controlled by only one set of muscles have a limited vocal range. This Song Sparrow, using several pairs, can put forth a cascade of trills and notes.

Elegant Black Terns breed in summer on secluded wetlands across the northern states and Canada. Because of major losses of wetlands in their breeding range — especially in Canada's prairie provinces — Black Tern numbers have dropped dramatically since the 1960s. The future of this beautiful bird depends on protecting and restoring high-quality wetlands. Recent research shows that artificial nest platforms can enhance the terns' breeding success.

Two eagles locking talons high above the ground might look like they’re risking injury, but it’s a normal courtship behavior called the “cartwheel display.” Fully entangled, the two birds begin spinning to the earth, disengaging just before they smack the ground. Their clasp could last for hours. At last, the eagles unlock talons and fly off. Rival adults sometimes perform the same flight. More info and transcript at BirdNote.org . Want more BirdNote?

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.

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 kno...

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 tran...

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 rig...

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 .

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 . Wan...

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....

During the days of mammoths and saber-toothed cats, California Condors thrived over much of the continent. Today, they're one of the most endangered birds in the US. The condor's main survival problem is high mortality due to lead poisoning. Condors eat animal carcasses, often containing lead from hunter's bullets. California law now requires hunters to use non-lead ammunition in the condor's home range - a change that could enable condors to once again thrive, and soar, in the wild. More info a...

After they leave the nest but before they take flight, many baby birds - especially robins and flickers - spend time on or near the ground. If you see such a baby bird, and your first thought is to "rescue" it, the better thing to do is let it be. Protect it from cats. Then watch from a distance, to see if an adult comes to feed it. If a bird or other animal is truly sick or injured, locate your local wildlife rehabilitator. More info and transcript at BirdNote.org . Want more BirdNote? Subscrib...

The way that some birds flick, wag, or flare their tails can be distinctive. A flicking or flashing tail might suggest to a predator that a bird is particularly alert or hard to catch, while also warning others in the flock of danger. Tail flicking can also help flush out prey. A Hooded Warbler -- or a Song Sparrow, like this one -- may flare its tail while foraging low to the ground to cause insects to jump, making them easier prey.

From a bird's perspective, the Dry Tortugas, a cluster of islands in the Gulf of Mexico, can be a life-saver. Millions of migratory songbirds fly north across the Gulf and Caribbean each spring, headed for North America. If they run into heavy wind and rain blowing down from the continent, the Dry Tortugas provide their first landfall. In a storm, thousands of storm-tossed birds – warblers, thrushes, cuckoos, and others – seek shelter on the Dry Tortugas. No doubt that this Blackpoll Warbler was...
