Деталі спостереження
Appeared large in comparison to swallows, unlike VASW which always stands out as a small bird among swallows. Throat was paler than the rest of underparts, but not strongly constrasting. Rump did not stand out as pale. Flight was less twitchy than is typical of VASW with long glides and fairly slow wingbeats. Obvious bulge in inner primaries when wings outstretched. Both observers felt that the bird was a chimney swift, but without the benefit of direct comparison with VASW and the relatively early date we felt it best to leave it unidentified
