Black-tailed Godwit (Limosa limosa islandica)

Here is the female of the pair. This species is the Palearctic equivalent of the Hudsonian Godwit (L. haemastica) which replaces it in the Americas. 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).
