Field notes

  • Named for the distinctive white feathers on its thighs, which distinguish it from the closely related Brown-cheeked Hornbill.
  • The male possesses a massive, creamy-white casque that is significantly larger and more convex than that of the female.
  • During nesting, the female is sealed inside a tree cavity with mud and droppings, relying entirely on the male to provide food through a narrow slit.
  • They are vital seed dispersers in tropical ecosystems, capable of carrying large seeds several kilometers from the parent tree.
  • The species is highly social and can occasionally be found in large communal roosts numbering up to dozens of individuals.
Habitat
Primary and mature secondary tropical lowland rainforests.
Range
Central and West Africa, ranging from Nigeria and Cameroon to Uganda and northern Angola.
