In this episode, the Private Eye tells his saddest story: his nemesis bird. That’s what birders call a species that keeps giving you the slip. His nemesis is the Painted Bunting, a colorful gem of a bird. When word of the species being spotted nearby reaches the PI, he rushes off to see it…

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the…

When a hawk is about to capture a songbird, the songbird has one last trick: a fright molt. It’s when a bird loses feathers due to sudden stress. This usually involves feathers near the tail or rump, where they’re most likely to be attacked as they flee. It can be a saving grace when the…

In 2019, several co-workers at the National Audubon Society formed a team for the World Series of Birding that focused on identifying female birds. Called the Galbatrosses, they sought to highlight how female birds have been understudied and unfairly written off as quieter and less…

The Arctic is still wintry when male Snow Buntings return to nesting areas in April. There's a big benefit to arriving early enough to claim a prime nest cavity in a rock face or under boulders, where it will be safer from predators. Nesting in chilly rock cavities means extra care must be…

Gentoo Penguins live in the frigid waters of the Atlantic. Only recently have scientists begun to unravel why penguin feathers don’t freeze. An electron microscope revealed tiny pores on the feathers that trap air, making the surface water repellent. This feature, plus a special coating…

At the end of summer, the once-bright feathers of a male American Goldfinch look ragged. Growing new flight feathers in a process called molting makes him more vulnerable to predators. Before migrating to wintering grounds, many songbirds stop at a secondary location to undergo the…

Most birds molt and regrow their flight or wing feathers—one at a time along each wing—to stay in prime condition for flying. But for a Wandering Albatross, with a whopping 10- to 12-foot wingspan, that’s a big job! It takes the large albatrosses a full year to molt, and they have to put…

Long-eared Owls aren’t rare, and they don’t live in remote locations. But their plumage and habits make them incredibly elusive. The mixture of warm browns and cool, bark-like grays lends the bird an astonishingly branch-like appearance. When potential predators approach, the birds close…

Some Harlequin Ducks migrate from the Pacific Coast all the way to the Teton Mountains in northwestern Wyoming to breed in the summer. White markings on both drakes and hens help them disappear amidst turbulent white water and rocks. Predators, like Peregrine Falcons, have a hard time…
