Breeding

African Grey Hornbill - Female (11)

The African Grey Hornbill is a monogamous bird which means that the bird finds and breeds with one partner for the rest of its life. The bird lay’s between 3 to 4 eggs and they are coloured white. It usually nests in natural holes in tree trunks or branches; once a site has been selected the female seals it from the inside with her own faeces. Most of its nests have a “chimney” or “funk-hole”, which a tunnel is leading out from the cavity that the female moves into if it feels threatened. It occasionally nests in rock crevices, barbet-made tree holes and nest boxes.
