Trumpeter hornbills breed in September-January. The nest in natural holes in trees, or sometimes in rocky crevices. After mating the female enters the nest and seals it with mud and faeces collected by the male, staying there until the chicks are ready to fledge. The female lays 2-5 white eggs, which she incubates alone for around 24 days while receiving food from the male. The chicks are fed by the female, from food collected by the male, and fledge 50 days after hatching.
