The bar-tailed godwit subspecies L. l. menzbieri breeds in north Siberia and winters in southeast Asia and northwest Australia. The subspecies L. l. taymyrensis breeds in northwest Siberia and winters in Africa, Persian Gulf and India.

The Important Bird and Biodiversity Areas (IBA) of the bar-tailed godwit species in Australia are, Eighty Mile Beach, Roebuck Bay, Great Sandy Strait, Moreton Bay and Pumicestone Passage.

Ecosystem and habitat

These bar-tailed godwit species do not normally occur in forest. They normally occur in altitudes from 0 to 440 meters.

The natural ecosystems and habitats of these bar-tailed godwit species include, tundra grasslands, tundra shrublands, wet river vallies, coastal marine lakes, freshwater lakes, intertidal mud flats, marshes, coral reefs, estuaries and freshwater lakes.

Diet and feeding behavior

The diet of the bar-tailed godwit consists mainly of invertebrates. Molluscs, crustaceans, polychaete worms, insects and insect larvae, spiders and earthworms are their primary food.

The bar-tailed godwit also feed on tadpoles, small fish, fruits, seeds, leaves and other plant matter. These godwits forage near the edge of water or in shallow water by probing the mud with their long sensitive bill.

Reproduction and breeding habits

The breeding season of these bar-tailed godwit species is from May to July in the Arctic summer of most of their breeding range. They are monogamous. Some females exhibit polyandrous behavior.

The bar-tailed godwit nesting sites are located in inland Arctic habitats, including dry positions in shrub tundra, montane tundra and hummocks. The nests are usually shallow scrapes in the ground, lined with lichen or plant material.

The clutch usually consists of two to five eggs. Both of the bar-tailed godwit parents take turns to incubate eggs. The chicks hatch out after 20-21 days of incubation.

Migration and movement patterns

These bar-tailed godwit species are migratory birds, breeding in northernmost Asia, Europe and Alaska and flying south for wintering.

The bar-tailed godwits leave the breeding grounds in Siberia and Alaska in mid-July onwards for wintering. The return migration commences in March and the godwits reach their breeding grounds in May. Several birds may stay back in their wintering range.
