Immature Bald Eagles look so different from mature Bald Eagles that John James Audubon thought they were a different species entirely! Sitting about three feet tall, these majestic birds have wingspans of more than six feet. Stretch your arms as far as you can, and imagine a bird whose…

Formerly known as the Gray Jay — and nicknamed the Camp Robber or Whiskey Jack — the mountain-dwelling Canada Jay seems to crash your picnic even faster than hungry ants. The fluffy, long-tailed jay will escape with any edible bits it can get, which it will store for the long mountain…

In June 1853, Thoreau wrote of an enchanting encounter with the Wood Thrush: "This is the only bird whose note affects me like music. It lifts and exhilarates me. It is inspiring. It changes all hours to an eternal morning." Wood Thrushes thrive in large expanses of forest. And their…

The male hummingbird leaves the female to build the nest and raise the young alone, but other father birds are more involved. A Peregrine Falcon father shares duties almost evenly with the mother. (Stewart, seen here, nested on a Seattle skyscraper for many years.) But the male Emu of…

Many birds look for islands when they want to find a great nesting site, because islands are often protected from mammalian predators. Some of the best places to find islands are oxbow lakes, like many of the ones protected by the National Wildlife Refuge System.

The song of this male Black-headed Grosbeak has been described as that of a drunken or scat-singing robin. Compare the songs of both birds, and draw your own conclusion! Singing Black-headed Grosbeaks can be heard from May well into summer, especially in streamside woods.

In Alaska’s Aleutian Islands, thousands of Whiskered Auklets — miniature relatives of puffins and murres — nest in deep rock crevices. The birds owe their name to the white plumes that sprout from their heads each summer. These fancy “whiskers” likely play a role in courtship. But they're…

Sandpipers spend most of their days running back and forth at the edge of the surf. They stick their long bills into the mud, looking for little crabs and critters and sea worms just below the surface.

The ancient Greeks believed the gods turned two distraught lovers into kingfishers — or “halcyon birds.” Thanks to divine assistance, these birds would enjoy calm weather during their nesting period. Even today, many kingfishers have echoes of this story in their scientific names.

Once common on the Atlantic Coast, Common Ravens became rare, as human activity grew more obtrusive through the 1900s. But something changed around the dawn of the 21st century. The ravens came back. Ravens now patrol parking lots in New Jersey to seize the choicest trash, dodge speeding…
