Taxonomy

In 1750 the English naturalist George Edwards included an illustration and a description of the marbled godwit in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Greater American Godwit". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the

The back is mottled and dark. They show cinnamon wing linings in flight.

Distribution and habitat

Marbled godwits breed in three distinct areas with their own unique route. The vast majority occur in mid-continental North America, followed by eastern Canada and the Alaska Peninsula, USA. In addition, the largest winter ranges are the Atlantic, Pacific and Gulf coasts of the US and Mexico. Godwits breeding in the western USA and Canada follow a route through the Utah stopover site, with a final arrival in the winter sites of Mexico and the Caribbean. Species breeding in eastern Canada migrate across the US, and stopover at sites along the Gulf of California and Mexico. Furthermore, those breeding in North and South Dakota winter in coastal Georgia. The Bear River Migratory Bird Refuge located at Great Salt Lake in Utah (USA), is one of the most popular stopover sites for godwits in the spring and fall.

Behavior and ecology

Breeding

They nest on the ground, usually in short grass.

Food and feeding

These birds forage by probing on mudflats, in

s, but also eat parts of aquatic plants. When the tide is in, they roost. They often sleep by standing on one leg and tucking their bill into their body (see picture below).

Conservation

Their numbers were reduced by hunting at the end of the 19th century. Although they had recovered somewhat since that time, their population has declined in recent times as suitable habitat is used for farming.
