On the legs there are rare feathers. From afar it is possible to mix up it with House Swallow; it is distinguished from House Swallow by the dark rump and dark breast band. Both sexes are similar; no seasonal differences of plumage. Juveniles are similar on adults but have on the uppaerparts the scaly parent formed by the buffy tips of the feathers.
