A real field recording of the African Grey Hornbill, made in the wild.
The African grey hornbill is a member of the hornbill family that normally lives across sub-Saharan Africa and the southwest Arabian Peninsula as a widespread resident breeder. It has, however, reached Florida where individuals have either escaped from captivity or been deliberately released. No breeding has been documented in the state, and the few birds that are seen are thought to survive only because new birds continue to arrive from these releases or escapes.
When it breeds, the female lays between two and four white eggs inside a tree hollow. During incubation she seals the entrance with a hard cement made from mud, droppings and fruit pulp, creating a protective wall around the clutch. This sealed chamber safeguards the eggs from predators and the elements while the female remains inside, relying on the male to bring food through the tiny opening until the chicks hatch.
The nest cavity is closed off leaving only a single narrow aperture, just wide enough for the male to slip food to the incubating female and later to the growing chicks. Once the chicks and the mother outgrow the sealed space, the female breaks out and rebuilds the wall, after which both parents take part in feeding the fledglings. This system ensures continuous nourishment while protecting the young during their most vulnerable stage.
Male African grey hornbills can be identified by a dark upper mandible marked with a creamy-yellow stripe, while females have a tricoloured bill tipped in red. The species' long, curved bill also bears a small casque on the upper culmen, which is more prominent in males than in females. Both sexes share the same overall grey-brown plumage, so the bill colour is the most reliable field clue.
The bird makes a distinctive piping call that sounds like "pee-o pee-o pee-o", a sound it uses to announce its presence across the savannah. This vocalisation is especially useful in the open woodland and savannah habitats the species prefers, allowing individuals to be heard over long distances. Its flight is undulating, which together with the call makes the hornbill conspicuous while moving between trees.

In the dappled light of the savannah, the African Grey Hornbill moves with deliberate purpose, its grey and white plumage blending seamlessly into the landscape as it forages for insects and seeds with its distinctive casqued bill. With each measured stride, its long legs carry it effortlessly across the grasslands, a master of understated elegance in a world of vibrant colours and bold displays. As it takes to the skies, its broad wings beat in a slow, powerful rhythm, a testament to the enduring beauty of this unassuming yet remarkable bird.
