African Grey Hornbill
Lophoceros nasutus
At 45–51 cm (18–20 in) in length, the African grey hornbill is a large bird, although it is one of the smaller hornbills. Its plumage is grey and brown, with the head, flight feathers and long tail being of a darker shade. There is a white line down each side of the crown and another down the back which is only visible in flight. Their long curved bills feature a small casque along the upper culmen, which is more prominent in males than females. A dark upper mandible with creamy-yellow mark or horizontal stripe is diagnostic of males, whereas females have tricoloured, red-tipped mandibles.

Crowned Hornbill
Lophoceros alboterminatus
It is a medium-sized bird, 50–54 centimetres (20–21 in) in length, and is characterized by its white belly and black back and wings. The tips of the long tail feathers are white. The eyes are yellow; the beak is red and presents a stocky casque on the upper mandible. In females, the casque is smaller. The crowned hornbill can be distinguished from the similar Bradfield's hornbill by its shorter beak.
