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…

Tropical rainforests are stunning places. Despite covering a small part of the Earth’s surface, they support half of the world’s biodiversity. The variety of lifeforms stands out visually in stunning color, and in sound through the strange and beautiful calls of birds. Today is World…

The Umatilla Chemical Depot in Oregon, a landscape dotted with a thousand concrete bunkers, may not look like an ideal haven for birds. But the site has taken on a new life — as a luxury subdivision for Burrowing Owls. That’s thanks in part to David H. Johnson, the founder of the Global…

Burrowing Parakeets excavate deep nest tunnels in sandstone and limestone cliffs in Argentina and Chile. The colony’s many tunnels zigzag and interconnect, creating an intricate labyrinth. Their nesting colonies are among the largest of any parrot — one in Argentina has 70,000 birds…

The Santa Marta Sabrewing is a hummingbird species so rare, they’ve only been documented twice in recent years. Native to the mountains of Colombia, they were officially described in 1946. No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to…

Although a field of grass might not seem like valuable habitat at first, many birds have adapted to nest in grassland habitats and nowhere else. In North America, birds such as the Bobolink seek out grasslands to raise their young, deftly hiding their nests within the dense vegetation…

You might think the first bird species that humans raised in captivity would be a relatively small one, like a chicken. But evidence suggests that people in New Guinea reared the cassowary, often called the world’s deadliest bird, as much as 18,000 years ago, long before the domestication…

Common Yellowthroats are one of the most abundant warblers in North America. They’re adaptable birds, thriving in places that pickier warblers pass over. So it’s easy to find yellowthroats in urban areas. Check for them in marshes, overgrown fields, and brushy areas along streams or trails…

Identifying birds by ear means getting familiar with each species’ unique voice. And that means learning the other voices in the ecosystem, too. Squirrels and chipmunks make calls that can sound a bit like bird calls at times. With practice, each species’ voice becomes more distinct and…

In 2022, ornithologists recognized the Chihuahuan Meadowlark as a separate species rather than a subspecies of the Eastern Meadowlark. Named after the northern region of Mexico where they're easy to find, Chihuahuan Meadowlarks live in dry desert grasslands. They form a distinct population…
