The Grey Go-away-bird (Corythaixoides concolor), also known as Grey Lourie, Grey Loerie, or Kwêvoël, 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, leaves, termites, and snails. The habitat it occupies is dry open savanna woodlands, farms, parks, and suburban gardens, often near water.
