African Southern Ground Hornbill

Tweet of the Day is the voice of birds and our relationship with them, from around the world.Miranda Krestovnikoff presents the African southern ground hornbill. Ground hornbills live in south and south east Africa. They're glossy black birds, as big as turkeys with huge downward-curving bills. The bird produces a deep booming sound that reverberates over long distances, sometimes as much as 5 kilometres, across its grassy habitat. Preferring to walk rather than fly, they strut about in the long grass, searching for prey. Snakes are a favourite: even deadly puff adders are no match for the birds' bludgeoning beaks.
