One of the most spectacular birds of our recent SA trip was the Yellow-knobbed Curassow.
Wikipedia describes this bird as follows: The Yellow-knobbed Curassow (Crax daubentoni) is a large species of bird found in forest and woodland in Colombia and Venezuela. It feeds mainly on the ground, but flies up into trees if threatened. Its most striking features are its crest, made of feathers that curl forward, and the fleshy yellow knob at the base of its bill. Females lack this fleshy yellow knob, but otherwise resemble the male in the plumage, being overall black with a white crissum. The adult is 84-92.5 cm (33-37 in) and weighs about 2-3 kg (4.4-6.6 lbs). It eats fruits, leaves, seeds, and small animals. Unlike most other gamebirds, curassows nest off the ground, with both sexes helping in the construction. The female lays just 2 eggs – a tiny clutch compared to those of many ground-nesting gamebirds. (Wikipedia)
Even though I saw these birds fairly up-close and personal for 3 days in a row, I was never able to get a really good photograph. My mother shot the last one in this series. Check these out.
