African Grey Hornbill

The African Grey Hornbill is one of the most widely distributed hornbills in Africa, found across a broad band of savanna and woodland habitats. Unlike its more boldly colored relatives, it has subdued grey-brown plumage, making it less conspicuous but still readily identified by its shape and behavior.

Appearance

• Grey-brown upperparts with fine pale streaking, and paler grey underparts
• A distinct pale, whitish eyebrow stripe above the eye
• Long, dark, slightly downcurved bill with a low bony casque ridge on the upper mandible, more developed in males
• Long tail with a white terminal band visible in flight
• Females and juveniles have a smaller casque and duller bill coloration than adult males

Key field marks

• Overall grey-brown plumage without bold black-and-white contrast
• Pale eyebrow stripe
• Dark bill with a low casque ridge, more prominent in males
• White-tipped tail visible in flight

Similar species

The Southern Yellow-billed and Southern Red-billed Hornbills are more boldly black-and-white with brightly colored (yellow or red) bills, whereas the African Grey Hornbill is more uniformly grey-toned with a dark bill, making it comparatively drab but distinctive within its range.

Habitat

This species occupies a wide range of open habitats, including savanna, dry woodland, thorn scrub, and cultivated areas with scattered trees.

Range

It has one of the broadest distributions of any African hornbill, occurring across the Sahel and sub-Saharan Africa from Senegal east to Ethiopia and south through East and southern Africa.

Migration

It is largely resident, though some populations may show local nomadic movements in response to food availability and rainfall.

Behavior

African Grey Hornbills are often seen singly, in pairs, or small groups, perching in trees and making short undulating flights between feeding sites. They are relatively unobtrusive compared to more colorful hornbill species.

Voice

The call is a distinctive, plaintive, whistled "pee-o pee-o" or similar piping series, often repeated and carrying well across open habitat.

Feeding

They have a varied diet including insects, small reptiles, fruit, and seeds, foraging both in trees and on the ground, and are known to follow army ant swarms or bushfires to catch disturbed prey.

Nesting & breeding

As with other hornbills, the female seals herself into a tree cavity nest using mud and droppings, leaving a narrow slit through which the male delivers food throughout incubation and early chick-rearing, until she breaks out partway through the nesting cycle.
