Swift, Common

Conservation status:

Common or Rare Migrant

Description:

Almost uniform sooty in fresh plumage, but brownish and more contrasting in worn plumage, though much depending on light conditions. Round whitish throat-patch variable, sometimes almost invisible; lacks contrast above but underparts show clearly paler inner flight-feathers than body and wing-coverts; deep tail-fork. Easily confused with Pallid, but note especially overall colour-tone, throat-patch, head pattern, upperparts contrast, and underparts markings.
