Orange River francolin
The Orange River francolin is a species of bird in the family Phasianidae found in grassland and woodland in Africa. In the taxa from the northern part of its distribution, the neck-line does not reach the eye and the belly is whitish. In the southern taxa the neck-line reaches the eye and the belly is buff. This has led some authorities to treat them as separate species: The Archer's or acacia francolin in the north, and the Orange River francolin in the south.
