Hudsonian Godwits are graceful shorebirds with long, slightly upturned bills, long legs, and a glorious breeding plumage of gold, brown, and brick red. They wade through arctic bogs and tidal mudflats, using their long bills to reach deep into the mud for invertebrate prey. They change to a subtle gray-brown nonbreeding plumage, and then undertake an incredible migration—nearly 10,000 miles The Hudsonian Godwit is a large shorebird with long legs and a long, slightly upturned bill. Size is quite variable (360-420 mm), with females averaging heavier (246-358 g) than males (196-266 g; 7 Hayman, P., J. Marchant, and T.

The Hudsonian Godwit (Limosa haemastica), known in the past as the Ring-tailed Marlin or Goose-bird, is the least well known of the world's four godwit species.With the majority of its population restricted to only a few remote sites during much of the year, it was long regarded as one of the rarest birds on the continent, ranked with the likes of the Kirtland's Warbler (Setophaga kirtlandii The Hudsonian Godwit has 10 functional primaries, 16-18 secondaries (including 4 tertials), and 12 rectrices. The godwits are diastataxic (see 18 Bostwick, K. S., and M. J. Brady (2002). Phylogenetic analysis of wing feather taxis in birds: macroevolutionary patterns of genetic drift? Auk 119(4):943-954.
