Swift

Apus apus
How to spot it
  • Uniformly dark, with no white anywhere
  • Stiff, scythe-shaped wings held like an anchor
  • Short forked tail, all sooty-brown
Birder's tip: All-dark with stiff swept-back wings, no white, unlike a Swallow or House Martin.

Swallow

Hirundo rustica
How to spot it
  • Long trailing tail streamers
  • Dark red throat and forehead on a glossy blue-black back
  • Creamy underparts, with no white rump
Birder's tip: The long tail-streamers separate it from the white-rumped House Martin.
