Scientific Name: Buteo platypterus

Rather small, compact hawk; about the size of Red-shouldered Hawk, smaller than Red-tailed Hawk. Adults are solid brown above, barred reddish-brown below with bold black-and-white tail bands. Immatures similar, but with blotchier markings below and thin, diffuse tail bands. Distinctive shape in flight: note the short tail, straight leading edge of wing, and bulging secondaries in flight. Listen for high-pitched, piercing whistle coming from woodlands during breeding season. Known for forming massive flocks called kettles during migration, when it travels from the U.S. and Canada all the way to winter in Central and South America.

In Costa Rica, the Broad-winged Hawk is most often seen during migration, when thousands may pass overhead in spectacular swirling groups. These kettles are an unforgettable sight, especially as the birds ride warm rising air currents to conserve energy on their long journey. Although some individuals may remain in the region during the winter months, many continue farther south. For birdwatchers, this species is a powerful symbol of seasonal movement, connecting the forests of North America with the tropical landscapes of Central and South America.
