Owls are magnificent animals that share our cities with us, and live in some of the most extreme environments on Earth. They range in size from huge, like the Blakiston’s Fish-Owl of Eastern Asia, to the songbird-sized Elf Owl, weighing less than half a deck of cards. Owls play key roles in their

El búho cornudo ( Bubo virginianus) es un cazador nocturno excepcional, gracias a sus agudos sentidos y su sigilo, pero son sus garras las que le permiten sujetar a una presa que forcejea. El más externo de sus cuatro dedos puede rotar hacia adelante o hacia atrás, una ventaja que la mayoría de las

White-winged Doves are common throughout Central America, the Caribbean, and North America’s Desert Southwest. Like the closely related Mourning Doves, they primarily eat seeds and grains. But in the Sonoran Desert, White-winged Doves time their migration to sync up with the Saguaros’ reproductive

Some birds have always called nocturnally, but other species are relative newcomers to the nighttime music scene, specifically in urban areas. Birds such as European Robins often sing well into the night. Scientists are studying what environmental cues might lead to this behavior. While artificial

The rainforests of Eastern and Northeastern Australia harbor many species of birds found almost nowhere else. This Eastern Whipbird — which is more often heard than seen — hangs out in the dense understory. Easier to lay eyes on is the large, pigeon-like Wompoo Fruit-Dove. Feathered in a stunning

During the breeding season, Double-crested Cormorants have two peaks of fishing activity: the first

Just a few weeks past the solstice, and the real heat of summer is yet to come. Some shorebirds are already on their way south, but most songbirds will be here for a while longer. What's the best time of day to look for them? Many birds are most active in the early morning, taking advantage of the

Zoos can be great places to see birds, and not just in an aviary – wild birds sometimes feel right at home in these urban green spaces. For example, Black-crowned Night Herons love nesting near bodies of water where they can catch fish, frogs, and other prey. They may find that the pond within a

Mientras muchas aves tienen huesos huecos que facilitan el vuelo, las aves buceadoras están diseñadas de otra manera. Los huesos de buceadores como el colimbo común (Gavia immer) son más densos que los de las aves canoras y otras expertas en el vuelo. Si tuvieran un esqueleto ligero, tenderían a
