I was interested in your odd hirundine Dave. Maybe worth remembering that Barn Swallows and Common House Martins do hybridize. We caught one at Ngulia on 23 Nov 2009 (two photos below), it showed characters of both species, as you'd expect, with a white rump, longer forked tail than a House Martin's, pinkish throat and distinct breast band but unfeathered tarsi. So your bird could have been a hybrid -- they do exist!
Cheers,
Graeme
