Kunene -Namibia January 2019 Swift (1 Viewer)

Looks to brown for a Apus apus and the vent is even lighter , could it be bradfieldi.

Bradfield's?

The tail looks deepy forked, almost a u shape with the extensions far apart, as if you would fold your middle fingers with index and little fingers extended and the middle two folded into the hand. It does appear to have a very pale vent and under tail coverts, while is really putting me off any possibilities for the area. The closest I get on shape alone, might be White-rumped Swift. It is too dark and the throat of Rogerio's bird does not look pale enough for W-r Swift. It may well be Bradfield's, but there is no pale vent and the tail fork doesn't look deep enough to me. I undestand Andy's question mark completely.
