Where to see them

Did you know…

The female seals herself into the nest cavity with mud and droppings, leaving only a narrow slit through which the male passes her food while she incubates.
From Rhinoceros Hornbill
It paints its own casque: the orange and red is not its own pigment but the secretion of the preen gland, which the bird rubs against the casque until it is stained, and a poorly preserved museum specimen loses that colour.
From Rhinoceros Hornbill
Like all Asian hornbills, the female walls herself into the nest hole for months, sealing the entrance and depending entirely on the male.
From Rhinoceros Hornbill
Unlike other hornbills, its casque is solid keratin, and males use it to butt heads in mid-air during territorial disputes.
From Helmeted Hornbill
Its solid casque is what is known as hornbill ivory, and on the Asian black market it fetches more than elephant ivory: that demand has caused a collapse so rapid that in 2015 the species jumped straight from Near Threatened to Critically Endangered.
From Helmeted Hornbill
The males fight by colliding casque-first in mid-flight, an impact that carries a long way through the forest and that no other bird in the world performs.
From Helmeted Hornbill
The male walls the female into a tree hollow with mud and feeds her for months.
From Great Hornbill
The female shuts herself inside a tree hollow and walls up the entrance with her own droppings, leaving only a slit through which the male feeds her throughout the incubation.
From Great Hornbill
