Ok, so its a photo of two Black Kites (Nov/Dec 2009, The Gambia), but are they one or two species?
The bottom bird is a classic Black Kite Milvus migrans migrans, which migrates between Europe and Sub-Saharan Africa. However the top bird is a 'Yellow-billed Kite' Milvus migrans aegyptius (Or Milvus aegyptius parasitus, if you prefer) which resides in West, East, and South Africa. Some say they are a different species. I'd go with that...
