Ground hornbills – or bucorvids – have been Tet Zoo mainstays since the early days of 2006. However, the only species that I ever feature is the Southern ground hornbill Bucorvus leadbeateri (sometimes incorrectly referred to by one of its junior synonyms, B. cafer). It’s easily recognisable for its red facial skin and low casque.
To bring balance, here’s the other species: the Abyssinian or Northern ground hornbill B. abyssinicus (this one photographed at Dublin Zoo). In contrast to its close relative, it has a much taller casque, and blue facial skin. Its throat pouch is blue in females but red in males.
Alas, poor old bucorvids: they so often get mentioned these days as mere azhdarchid analogues.
