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.
Widespread throughout its large range, the trumpeter hornbill is evaluated as least concern on the IUCN Red List of Threatened Species.
They do not rely on swamp forests - but do feed in this habitat when fruit is available. The main fruit is from Ficus trichopoda.
