The female's gular skin is blue, whereas the male's is bright yellow; his neck is white and his nape dark reddish passing into black. Sexual dimorphism in the colouration of plumage and inflatable gular skin is less pronounced in young wreathed hornbills, but becomes more apparent as both sexes mature. It is a medium-sized bird with a body length of 75 to 90 cm (30 to 35 in); adult males weigh from 1.68 to 3.65 kg (3. Voice: The main call of the wreathed hornbill is a loud double yelp that has been described to sound like "coo-cuk" or "wuff-wurff". This call is short and typically repeated in a sequence of three or more from a perching position or during flight. The second part of the call is higher pitched and louder than the first and can be heard from farther distances.
