Southern Ground Hornbill
Bucorvus leadbeateri
unting in fairly tall grass at Maasai Mara, Narok County, Kenya. October 2016.
From Wikipedia:
The southern ground hornbill is characterized by black coloration and vivid red patches of bare skin on the face and throat (yellow in juvenile birds), which are generally believed to keep dust out of the birds eyes while they forage during the dry season. The white tips of the wings (primary feathers) seen in flight are another diagnostic characteristic. The beak is black and straight and presents a casque, more developed in males.
