Alison Vilag has worked for half a decade as a fall and spring waterbird counter at remote migration hotspots around Lake Superior. For weeks, every day from sunrise to nearly sunset, Alison is outside in frigid and volatile weather, identifying species from afar and tallying them with a clicker

The world is full of poisonous creatures. Some butterflies, beetles and frogs use bright colors to warn birds and other predators that they’re full of toxins. But you might be surprised to learn that some birds are poisonous, too. Birds called Hooded Pitohuis carry toxins produced by a beetle that

Los pingüinos de Humboldt que habitan a lo largo de la costa del Pacífico de Chile y Perú, están adaptados al frío. Pero en tierra las temperaturas alcanzan los 37 grados y los pingüinos tienen que refrescarse. Por este motivo, tienen parches de piel desnuda de color rosa en la cara, bajo sus alas y

A captive breeding program has helped set California Condors on the path to recovery. But when biologists reviewed the family tree for the breeding program, they found a big surprise. Two chicks had DNA that linked them perfectly to their mothers but didn’t match a single male. They arose through

The sight and sound of the Bare-throated Bellbird — the national bird of Paraguay — inspires wonder and delight. Its presence as an indicator species and seed disperser also bodes well for ecosystem health in the Alto Paraná Atlantic Forests that stretch from Southeast Brazil through eastern

When biologist Danielle Whittaker started studying bird odors, some scientists tried to discourage her, claiming that birds can’t smell. But that only deepened her curiosity. Once, she caught a whiff of a cowbird, which smelled to her like sugar cookies. Danielle and her colleagues studied Dark-eyed
