About Poicephalus robustus (Gmelin, 1788)
The Cape parrot (Poicephalus robustus) is a moderately large, short-tailed bird with a very large beak. This beak is adapted to crack all kinds of hard nuts and fruit kernels, especially those from African yellowwood trees of the genus Podocarpus. This feeding specialization differs from its close relative, the savanna-dwelling Poicephalus fuscicollis, which feeds on a wide range of trees from tropical woodlands, including marula, Commiphora species, and Terminalia species. Cape parrots are sexually dimorphic: females typically have an orange frontal patch on the forehead. Juveniles also have a larger orange-pink forehead patch, but they do not have the red plumage on the shoulders and legs that adult birds show. These plumage traits vary between individual birds and across the three recognized forms of the species. The Cape parrot is endemic to South Africa. It lives in Afromontane forests at moderate altitudes in eastern South Africa, ranging from the coastal escarpment near sea level up to midlands at around 1000 meters. These Afromontane forests form a series of small patches across southern and eastern South Africa, and are dominated by three yellowwood species: Podocarpus latifolius, Podocarpus falcatus, and Podocarpus henkelii. Cape parrots have a disjunct distribution. The largest population is centered in the Amathole mountains of Eastern Cape Province, and extends east with several large gaps through the Mthatha escarpment and Pondoland in Eastern Cape, and across the southern midlands of KwaZulu-Natal Province to Karkloof near Pietermaritzburg. A very small population of around 30 individuals lives over 600 kilometers further north, in the Magoebaskloof area of Limpopo Province. Cape parrots are not found in large sections of Afromontane forest, including the forests along South Africa's southern coast near Knysna, the higher altitude Afromontane forests in the Drakensberg mountains of KwaZulu-Natal, and the moderate-altitude forests of northern KwaZulu-Natal province and Eswatini. These unoccupied areas separate the KwaZulu-Natal midlands population from the Limpopo escarpment population. All these unoccupied areas fall within the typical dispersal range of Cape parrots, and there are historical records of Cape parrots from northern KwaZulu-Natal.
