The Hook-billed Kite is a mid-sized, slender raptor with a striped belly and banded tail. It is known for its diet consisting mainly of arboreal snails, taken while climbing in trees, walking about in upper branches and looking for tree snails. Both the male and female help to build a loose nest of sticks. Both parents help to incubate the eggs and raise the young.

Hook-billed Kite

Chondrohierax uncinatus

Diet

  • Specializes in feeding on tree snails, which it extracts from their shells with its strongly hooked bill.

  • Also eats slugs, insects, frogs, lizards, small birds, eggs, and occasionally small mammals.

  • Hunts by searching trees and branches for arboreal snails and other prey.

Range

  • Found from southern Mexico through Central America, the Caribbean, and much of South America to northern Argentina.

  • In Mexico, it occurs mainly in the tropical lowlands of both the Pacific and Gulf slopes, including the Zihuatanejo region, although it is generally uncommon and local.

  • Inhabits tropical dry forests, tropical evergreen forests, gallery forests, forest edges, mangroves, and mature secondary forests.

  • Generally a year-round resident.

Male / Female

  • Male: Occurs in light, intermediate, and dark colour morphs; slightly smaller than the female. All morphs have the characteristic strongly hooked bill.

  • Female: Similar in plumage and also occurs in multiple colour morphs but is noticeably larger and heavier.

  • Sexes cannot be reliably distinguished by plumage; size is the primary field difference.

  • Both sexes have variable bill sizes, reflecting adaptation to different sizes of tree snails.

Size

  • Length: 38–51 cm (15–20 in)

  • Wingspan: 76–91 cm (30–36 in)

  • Weight:

    • Male: 250–350 g

    • Female: 350–500 g
