This  is a Rock Martin, a lifer for me which I photographed from the edge of a cliff at Cape Point National Park the other day, it is one of at least 3 new species of hirundines and Swifts photographed (with varying degrees of success on this trip). This is a slow flying martin which made it possible to get a photograph.  Last evening I saw a couple of Little Swift fly past the the apartment, I went for the camera but they didn't return unfortunately.
