Hornbill
A hornbill is a large, striking bird found mainly in tropical and subtropical forests of Asia and Africa, known for its long curved bill and the distinctive casque (helmet-like structure) on top.
Ecological Importance
Hornbills are called “farmers of the forest” because they disperse seeds over large areas, helping forests regenerate.
