The trumpeter hornbill (Bycanistes bucinator) is a medium-sized hornbill, with length between 58 and 65 cm (23 and 26 in), characterized by a large grey casque on the bill, smaller in females. The eyes are brown or red, with pink surrounding skin. Body mass is between 0.45 and 1 kg (0.99 and 2.20 lb). It is similar to silvery-cheeked hornbill. Distinguishing features include an all-black back, white belly and white underwing coverts (in flight, wings present white tips), and red facial skin. The trumpeter hornbill is a gregarious bird, usually living in groups of two to five individuals, although sometimes as many as fifty. Wikipedia →
