The Solomons cockatoo (Cacatua ducorpsii), also known as the Ducorps' cockatoo, Solomons corella or broad-crested corella, is a species of cockatoo endemic to the Solomon Islands. This small white cockatoo is larger than the Tanimbar corella yet smaller than the umbrella cockatoo. The species is common across most of the Solomons, absent only from Makira in the south. It inhabits lowland rainforests, secondary forests, cleared areas and gardens.
