whooping crane: see crane.

Migratory North American bird (Grus americana) and one of the world's rarest birds, on the verge of extinction. The tallest North American bird, it is almost 5 ft (150 cm) tall and has a wingspread of about 7 ft (210 cm). It is white with black-tipped wings, black legs, and a bare red face and crown. Its shrill, whooping call can be heard for 2 miles (3 km). Almost exterminated in the early 20th century, it became the object of intensive conservation efforts; by century's end there were still fewer than 300 wild and captive individuals.
