The yellow-billed kite (Milvus aegyptius) is the Afrotropic counterpart of the black kite (Milvus migrans), of which it is most often considered a subspecies. However, recent DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species.
There are two subspecies: M. a. parasitus, found throughout most of sub-Saharan Africa (including Madagascar), except for the Congo Basin (with intra-African migrations) and M. a. aegyptius of Egypt, south-west Arabia and the Horn of Africa (which disperses south during the non-breeding season).
As suggested by its name, the yellow-billed kite is easily recognized by its entirely yellow bill, unlike that of the black kite (which is present in Africa as a visitor during the North Hemisphere winter). However, immature yellow-billed kites resemble the black kites of the corresponding age.
