The wrinkled hornbill or Sunda wrinkled hornbill (Rhabdotorrhinus corrugatus) is a medium-large hornbill which is found in forest in the Thai-Malay Peninsula, Sumatra and Borneo. The wrinkled hornbill is around 70 cm long, and has a very large bill that is fused to the skull. It has mainly black plumage, a blue eye-ring, and a broadly white or rufous-tipped tail. The male and female have different head and bill patterns. Males have bright yellow feathers on the auriculars, cheeks, throat, neck-sides and chest, but these areas are black in the female, except for the blue throat. The bill of the male is yellow with a red base and casque, and a brownish basal half of the lower mandible. Wikipedia →
