Fun Facts

Males can be easily distinguished from females by the color of their throats. The male’s throat skin is yellow; the female’s is blue.

Males and females pair for life.

The specialized knobs on the tops of the birds’ beaks are known as casques. These are believed to function as signals of dominance and gender.

Lifestyle
In the wild, wreathed hornbills can be found roosting in large flocks. Males and females pair for life. During breeding season, a pair chooses a territory and finds a nest site. Pairs may reuse the same nests for several years.

Food
In the wild, wreathed hornbills eat primarily fruit. When males are feeding nesting females or growing chicks, they may also offer insects, crustaceans and small reptiles or amphibians.

Life Cycle
When the female is ready to lay her eggs, she creates a nest in a tree cavity. The male then encloses her completely in the cavity, sealing it with mud, fruit and feces. He leaves only a narrow slit through which he feeds her and her offspring. The female and her chick(s) are completely dependent on the male for their survival for about four months. Although females may lay up to three eggs, usually only one chick survives.

Population Status & Threats
Although wreathed hornbills are not currently endangered, the species could be threatened in the future by habitat loss. This species has a large range, but habitat loss caused by deforestation is resulting in a decline in wild wreathed hornbill populations in Southeast Asia.
