Bar-tailed Godwit Limosa lapponica
Scientific classification
Kingdom: Animalia Phylum: Chordata Class: Aves Order: Charadriiformes Family: Scolopacidae Genus: Limosa Brisson, 1760
Species
4, see text.

The godwits are a group of large, long-billed, long-legged and strongly migratory wading birds of the genus Limosa. They form large flocks on coasts and estuaries in winter.

They can be distinguished from the curlews by their straight or slightly upturned bills, and from the dowitchers by their longer legs. The winter plumages are fairly drab, but three species have reddish underparts when breeding. The females are appreciably larger than the males.

Family Scolopacidae

• Genus Limosa
  • Black-tailed Godwit, Limosa limosa
  • Hudsonian Godwit, Limosa haemastica
  • Bar-tailed Godwit, Limosa lapponica
  • Marbled Godwit, Limosa fedoa

In addition, there are one or 2 species of fossil prehistoric godwits. Limosa vanrossemi is known from the Monterey Formation (Late Miocene, approx. 6 mya) of Lompoc, USA. Limosa gypsorum of the Late Eocene (Montmartre Formation, some 35 mya) of France may have actually been a curlew or some bird ancestral to both curlews and godwits (and possibly other Scolopacidae), or even a rail, being placed in the monotypic genus Montirallus by some (Olson, 1985). Certainly, curlews and godwits are rather ancient and in some respects primitive lineages of scolopacids (Thomas et al., 2004), further complicating the assignment of such possibly basal forms.

A female bar-tailed godwit holds the record for the longest non-stop flight for a land bird.
