Similar Species

Bar-tailed Godwit whose bill has a slightly upcurved tip and narrowly barred tail. Hudsonian Godwit of the Americas is very similar. They can be distinguished in all plumages by their underwing patterns, white in Black-tailed and mostly dark in Hudsonian. However there are other differences. The bill is straight on Black-tailed, not noticeably upturned. Also Black-tailed has a broader, longer white wing stripe and broader white tail band (Hudsonian has less white in its tail).

Distribution

Breeds in northern Palearctic; winters to southern Africa, southern Asia and Australia.

  • L. l. islandica: Smaller, darker, with more extensive red on belly in Spring.
  • L. l. limosa: Larger, paler.
