The Wrinkled Hornbill (Rhabdotorrhinus corrugatus) is a large bird species native to the rainforests of Southeast Asia, particularly found in Borneo and Sumatra. It is characterized by its striking appearance, featuring a black body with wrinkled skin around its eyes and throat, a large yellow bill with a casque (a hollow structure on top), and white-tipped tail feathers. The Wrinkled Hornbill primarily feeds on fruits, figs, and insects found in the forest canopy. It plays an essential role in seed dispersal, helping to maintain the biodiversity of its habitat.
