Magnificent Frigatebirds are huge, gangly seabirds found around the warm waters of the Western Hemisphere. When it comes time to mate, males inflate giant red throat sacs, then rattle and drum their bills against them to create jazzy percussive sounds.

Where some noises — like TV, traffic and random conversations — can make it hard to concentrate, birdsong may make it easier. In Alder Hey Children’s Hospital in Liverpool, England, the sweet sounds of birdsong carry along the hallways. In an Amsterdam airport, a lounge plays bird sounds…

What’s the reddest bird in North America? In the East, the Scarlet Tanager or maybe the Summer Tanager. But neither is seen nearly as often as the Northern Cardinal. In the Southwest, another candidate pops out like a bright red flare on the tip of a branch: the Vermilion Flycatcher. This…

The Vulturine Guineafowl is a striking bird. It lacks feathers on its head and neck and has a blue breast with silvery plumes. The species has a complex social structure. Distinct groups, similar to high school cliques, mingle but don’t change membership. Such a multilevel society was…
