Description
The total length is 40–50 cm (16–20 in), including a large bill of 8–13 cm (3.1–5.1 in), and wingspan is 70–88 cm (28–35 in). Body mass can vary from 240 to 510 g (8.5 to 18.0 oz). Adults have long blue-grey legs and a very long pink bill with a slight upward curve and dark at the tip. The long neck, breast and belly are pale brown with dark bars on the breast and flanks. The back is mottled and dark. They show cinnamon wing linings in flight.

Feeding Habits
Marbled Godwit's diet includes aquatic invertebrates, earthworms, insects, mollusks, crustaceans, plant tubers, leeches, and small fish. They probe mud or sand to forage, picking prey from the surface or submerging their head, even in water up to 5 inches deep.
Habitat
Marbled Godwit are typically found in a range of wetlands, favoring shortgrass prairies close to wetlands for breeding, particularly where the vegetation is lower. Ideal breeding conditions include prairies with grasses like green needle grass, western wheatgrass, and blue grama. They select habitats away from taller plant growth. Non-breeding habitats for marbled Godwit extend to coastal environments, where they inhabit mudflats, estuaries, and sandy beaches, searching for food and resting sites. These birds do not typically frequent forested or urban areas, and their habitat selection remains constant across their range.
Nest Behavior
The female marbled Godwit selects one of the male's depressions to lay eggs. Nesting activities occur far from water, with incubation and parental care jointly managed by both parents after egg-laying.
Nest Characteristics
Marbled Godwit's nest is a shallow depression on the ground with little cover, found in shortgrass prairies. It's lined with grasses and lichen, formed primarily by the male creating several depressions.

Migration Overview
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.
General Info
Behavior
Marbled Godwit exhibit various behaviors that are integral to their survival and breeding. These birds engage in wading through shallow waters, occasionally swimming, or traversing shortgrass prairies. They display recognizable flight patterns with a sharp profile and pointed wings, often sleeping while standing on a single leg with their bill tucked in. During breeding, males establish expansive territories and perform impressive flight displays to court mates, emphasizing their monogamous bonds. Post-breeding season, marbled Godwit remain loyal to their breeding areas and partners annually. In nonbreeding seasons, they forage in groups alongside other shorebirds, showcasing their adaptability and social nature within their ecosystem.
Species Status
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.
