Black-cheeked lovebird  (Agapornis nigrigenis)

The lovebirds comprise nine species of small but solidly built parrots, renowned for their strong pair bonds (4). The black-cheeked lovebird is bright green except for a dark brown head, olive nape, bold white eye-ring, red bill and an orange patch on the chest. The juvenile is similar in appearance to the adult bird, but its bill is grey or orange. In common with the screeching chatter of other lovebirds, this species has a loud, shrill call (2) (5).
