Hook-billed Kite - Chondrohierax uncinatus The Hook-billed Kite is a rather odd raptor that just reaches the U.S. in extreme southern Texas. It was unknown in the U.S. until the 1960s, but now seems to be a permanent resident in the forested woodlands along the Rio Grande. The strongly hooked bill is used to extract the "meat" from its main prey, tree snails. The species has a widespread geographic range, and is found in much of Mexico, Central America, and South America. Plumage and bill size are quite variable between geographic locations, with bill size seemingly correlated to the size of snails in their foraging range.

Habitat: Seems to be found in most forested habitats where tree snails are common. In the tiny U.S. portion of their range, they are found in deciduous forests along the Rio Grande.

Diet: Feeds mostly on tree snails, although they will also take large insects, small lizards and snakes, and small amphibians.

Behavior: Climbs through the vegetation more like a parrot than a raptor, searching for tree snails.

Nesting: Both the male and female help to build a loose nest of sticks. Both parents help to incubate the eggs and raise the young.

Song: Gives a cackling series of chatters.

Migration: Considered a permanent resident throughout its range.
