Bar-tailed and Black-tailed Godwit, a comparison

Two fairly common birds on the north Norfolk coast at this time of year are the Bar-tailed Godwit (photos above) and the Black-tailed Godwit (photos below). Superficially similar, in the fact that they both have long legs, long bills and are brown/grey, but are easily told apart, especially when seen together. The 'Barwit' is a smaller, more chunky looking bird, with shorter legs, an upturned bill and a distinct supercilium in its' winter plumage. The 'Blackwit' is a larger bird with an unfathomably long, straight bill, longer legs and a shorter, less distinct supercilium.
