Cape parrot
The Cape parrot (''Poicephalus robustus'') or Levaillant's parrot is a large, temperate forest dwelling Poicephalus parrot endemic to South Africa. It was formerly grouped as a subspecies (along with the savanna-dwelling brown-necked parrot ''(P. fuscicollis fuscicollis)'' and grey-headed parrot ''(P. f. suahelicus)'') but is now considered a distinct species.
==Description==
The Cape parrot is a short-tailed moderately large bird with a very large beak used to crack all sorts of hard nuts and fruit kernels, especially those of African yellowwood trees ''Podocarpus'' spp.. This contrasts with the closely related savanna species (''Poicephalus fuscicollis'') which feeds on and a wide variety of tropical woodland trees such as Marula, ''Commiphora'' spp. and ''Terminalia'' spp. These species are sexually dimorphic, with females typically sporting an orange frontal patch on the forehead. Juveniles also show a larger orange - pink patch on the forehead but lack the red on shoulders and legs of adults.〔Downs, C.T. 2005.
