The Grey Go-away-bird, also known as Grey Lourie, is a southern African bird of uniform grey with black beak and strikingly pink gape. It is widespread in savanna woodland, a clumsy flier though extremely agile in clambering through tree crowns. It has a distinctive loud alarm call "quare", fancifully sounding like "Go-away". The crest is raised when excited. Its diet is mainly fruit (such as wild figs and berries), flowers, buds, termites, and snails.
