American Bitterns nest in marshes across the northern half of the United States and throughout much of Canada, and they winter along both U.S. coasts south into Central America. But in some places, bitterns are in serious trouble. Much of the extensive, shallow marshland they once bred in has been

Hummingbirds are celebrated for their beauty and grace, but in some places, they are trapped in a dark and deadly tradition. In parts of Mexico, hummingbirds are captured and killed to be used in love spells called chuparosa charms, a practice that has crossed borders and made its way to the United States. Conservationists are working to save these…

But in some places, bitterns are in serious trouble. Much of the extensive, shallow marshland they once bred in has been drained or degraded by chemicals and silt. BirdNote i…

Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers who first

Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers who first described these species to dub them “the ‘ultimat…

Both this Eastern Towhee and the Spotted Towhee of the West sport a black or dark brown hood and back. And when they fly, their tails flash white. When a hawk gives chase, the towhee's flashing tail-feathers draw the predator's attention. Momentarily distracted, the hawk may come up with just a

Both this Eastern Towhee and the Spotted Towhee of the West sport a black or dark brown hood and back. And when they fly, their tails flash white. When a hawk gives chase, the towhee's flashing tail-feathers draw the predator's attention. Momentarily distracted, the hawk may come up with just a couple of tail feathers — as the towhee escapes into t…

The 'Akiapōlā'au is a bright yellow bird with a black eye mask, found only in the upper elevations on the Big Island of Hawai'i. But its most distinct feature is its totally unique, uneven bill. The top of the bill is long, skinny, and curved like a sickle. Once abundant, habitat loss and disease

The 'Akiapōlā'au is a bright yellow bird with a black eye mask, found only in the upper elevations on the Big Island of Hawai'i. But its most distinct feature is its totally unique, uneven bill. The top of the bill is long, skinny, and curved like a sickle. Once abundant, habitat loss and disease from mosquitoes has taken a toll on the 'Akiapōlā'au…

Descriptive names can be a great help when you’re getting to know a new bird. Some species have common names that put their plumage pattern front and center – like the Five-striped Sparrow. If you encounter a bird described as flammulated, lineated, banded, or barred, keep an eye out for their

Descriptive names can be a great help when you’re getting to know a new bird. Some species have common names that put their plumage pattern front and center – like the Five-striped Sparrow. If you encounter a bird described as flammulated, lineated, banded, or barred, keep an eye out for their namesake stripes and streaks! BirdNote is grateful to t…

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

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 wetl…

Skateboarder and birder Dave Mull remembers the first time he heard a Steller’s Jay imitating a Red-tailed Hawk. “These Steller's Jays were pretending to be something they were not, kind of tricking the world,” he says. It got him into the mindset that he could attempt a terrifying new skateboard

Skateboarder and birder Dave Mull remembers the first time he heard a Steller’s Jay imitating a Red-tailed Hawk. “These Steller's Jays were pretending to be something they were not, kind of tricking the world,” he says. It got him into the mindset that he could attempt a terrifying new skateboard trick called the “stump jump.” Music in today's epis…

Roosters don’t need to set an alarm to tell them when it’s time to crow — their internal circadian clock lets them anticipate sunrise with remarkable accuracy. To us sleepy humans, it may seem like they all start crowing at once. But scientists have found that roosters follow a strict social

Roosters don’t need to set an alarm to tell them when it’s time to crow — their internal circadian clock lets them anticipate sunrise with remarkable accuracy. To us sleepy humans, it may seem like they all start crowing at once. But scientists have found that roosters follow a strict social hierarchy: only the top bird can issue the first cock-a-d…

Hudsonian Godwits are tough birds to find, and they were once thought extinct due to overhunting. After nesting at sites scattered in the High Arctic, they migrate south on a route that takes them over the ocean from Canada to South America. In spring, they head north through the Great Plains

Hudsonian Godwits are tough birds to find, and they were once thought extinct due to overhunting. After nesting at sites scattered in the High Arctic, they migrate south on a route that takes them over the ocean from Canada to South America. In spring, they head north through the Great Plains. Populations are estimated to be in the tens of thousand…

In August 2008, Kasatochi Island erupted in the middle of auklet breeding season, burying tens of thousands of chicks in hot ash. At first, the auklets’ future on the island appeared bleak. But in just a few years, the birds had returned in force. Thousands nested within the innumerable chambers

In August 2008, Kasatochi Island erupted in the middle of auklet breeding season, burying tens of thousands of chicks in hot ash. At first, the auklets’ future on the island appeared bleak. But in just a few years, the birds had returned in force. Thousands nested within the innumerable chambers left behind by sea-cooled lava. More info and transcr…

Beaks suited for opening tough, hard seeds — thick, conical beaks — evolved in more than one lineage of birds. Rose-breasted Grosbeaks are related to cardinals, which also have powerful beaks. Evening Grosbeaks belong to the finch family, which includes goldfinches and crossbills — an entire family

We make it a habit to detail the broad and beautiful spectrum of bird colors, but iridescent feathers are undoubtedly among the most mesmerizing. When sunlight hits the Bufflehead’s dark head feathers at the right angle, their colors transform into shades of the rainbow, from deep violet to green

Ross’s Geese and Snow Geese are both white-bodied waterfowl with black wingtips that can be difficult to tell apart. The pair are a great example of what science calls sister species, which occur when a portion of one species takes an evolutionary step away from the rest, resulting in a species

Ross’s Geese and Snow Geese are both white-bodied waterfowl with black wingtips that can be difficult to tell apart. The pair are a great example of what science calls sister species, which occur when a portion of one species takes an evolutionary step away from the rest, resulting in a species split. In this case, genetic studies suggest that the …

Found in the Sierra Madre, the Arizona Woodpecker has a special connection to the mountain range. Sharing mid-elevation pine and oaks with fellow border straddlers, these small brown birds with white and brown cheeks stand out from other Woodpeckers with their heavily marked white underparts

Found in the Sierra Madre, the Arizona Woodpecker has a special connection to the mountain range. Sharing mid-elevation pine and oaks with fellow border straddlers, these small brown birds with white and brown cheeks stand out from other Woodpeckers with their heavily marked white underparts. Uniquely, they forage by flying to the base of a tree an…

Swainson’s Hawks make an incredible journey every year, migrating 12,000 miles round-trip from North America’s prairies to Argentina’s pampas. What makes them truly unique is their diet. Most hawks hunt rodents and reptiles, but Swainson’s Hawks switch to insects, feasting on grasshoppers and locusts in South America. In the 1990s, this diet nearly…
