Appearance, physical description and identification

The black-tailed godwit (Limosa limosa) is a fairly large godwit, measuring 35 to 45 cm in length. These birds are sexually dimorphic, the male weighs 160 to 440 grams and the female weighs 250 to 500 grams.

The black-tailed godwit has dull pink-chestnut breast, upper belly, neck and head during summer. The wintering birds have pale grayish brown plumage. There is a pale supercilium and a dark lore. There is dark brown barring on the back and wings. The tail is black.

The godwit bill is long and straight. It is orange yellow near the base and blackish towards the distal end. In wintering birds, the base of the bill is pinkish. The irises are dark. The legs are long and dark gray in color. The feet project well beyond tail in flight.

In flight, the characteristic white wing-bar, white rump and blackish tail are clearly seen. The godwit call is a strident "weeka..weeka..weeka" or subdued, plaintive "kip..kip..kip" or "chut..chut..chut" sound.

Origin, geographical range and distribution

The black-tailed godwit species is distributed in Indian subcontinent, southeast Asia, Australia, Europe, Africa and Asia.

The black-tailed godwit nominate subspecies L. l. limosa is distributed in west and central Europe and western Russia. This subspecies winters in Mediterranean region, sub-Saharan Africa, Middle East, Afghanistan, Pakistan and western India.

The black-tailed godwit subspecies L. l. islandica is distributed in Iceland, Faroe Islands (Denmark), Shetland Islands (UK) and Lofoten Islands (Norway). This godwit subspecies winters in Ireland, Britain, western France, Spain and Portugal.

The godwit subspecies L. l. melanuroides is distributed in central Russia, east Mongolia, northeast China and northeast Russia. This subspecies winters in India, Myanmar, Thailand, Cambodia, Vietnam, Malaysia, Indonesia, Philippines, New Guinea, Australia and Taiwan.

In India, wintering black-tailed godwits are distributed in Mizoram, Manipur, Tripura, West Bengal, Odisha, Bihar, Uttar Pradesh, Uttarakhand, Haryana, Rajasthan, Gujarat, Madhya Pradesh, Chhattisgarh, Maharashtra, Telangana, Tamil Nadu and Karnataka.

Vagrant black-tailed godwits have been observed in United States, Canada, Puerto Rico, Trinidad and Tobago, Seychelles, Zimbabwe, Namibia, South Africa, Congo, Malawi, Comoros, Madagascar, Maldives, Greenland (Denmark) and New Zealand.

The Important Bird and Biodiversity Areas (IBA) of these black-tailed godwit species in India are, Wild Ass Wildlife Sanctuary, Veeranam Lake, Chilika Lake, Kunthur - Kallur Lakes, Kaj Lake and Bhitarkanika Wildlife Sanctuary.

The IBA of these black-tailed godwit species in Iceland are, Skúmsstadavatn, Ósasvædi Ölfusár, Hólmarnir and Austara Eylendid. The IBA in China are, Coastal mudflat of Tianjin, Shuangtai Estuary, Yalu Jiang Estuary and Kaidu River Valley.

Some of the IBA of these black-tailed godwit species in Russia are, Khayryuzova bay, Malakchan bay, Moroshechnaya River, Nevskoye Lake, Chonta, Bylinskaya, Ubinskoye Lake, Kurtan Lake. Chernoye Lake, Ul'skoye bog, Tsninski Forest and Manychstroi area. E

Ecosystem and habitat

These black-tailed godwit species do not normally occur in forest. They normally occur in altitudes from 0 to 1000 meters.

The artificial ecosystems and habitats of these godwit species include agricultural lands, pasture lands and urban areas.

The natural ecosystems and habitats of these black-tailed godwit species include, wetlands, estuaries, freshwater lakes, lagoons, marine lakes, tide pools, mudflats, marshes, and temperate grasslands.

Diet and feeding behavior

The diet of these black-tailed godwit consists mainly of insects. Insects, insect larvae, chironomid larvae, beetles, grasshoppers, locust, cicadas, crickets, spiders, maggots, annelid and polychaete worms, molluscs and crustaceans are their primary food.

These godwits also feed on seeds, grains and berries. These species forage on the ground and in shallow water, picking insects and other small prey. The bill is very sensitive and is used for probing mud for locating prey.

Reproduction and breeding habits

The breeding season of these black-tailed godwit species is from April to June in most of their breeding range. They breed in loose colonies. These birds are monogamous. Both of the pair build their nest.

The nesting sites of the black-tailed godwit include grounds with high grass and soft soil, pasturelands, hayfields, wet grasslands, grassy marshlands, steppes and occasionally sandy areas.

The black-tailed godwit nest is a shallow scrape lined with thick layer of stem grass, leaves and other plant material. The clutch may contain three to six olive-green eggs with brown mottling. The breeding pair take turns to incubate the eggs for 23-25 days. The godwit chicks may fledge 25-30 days after hatching.

Migration and movement patterns

These black-tailed godwit species are fully migrant birds.

Migratory black-tailed godwit populations occur in Iceland, central and northern Europe, central and northwest Asia, Mongolia, northern China and northeast Russia. They migrate on a broad front and make long-distance southward flights during July and October for wintering.

The wintering populations of black-tailed godwit make return migration to the breeding grounds from February to April. Many one-year old birds may remain in their wintering range during the summer. Non-breeding birds in the breeding range may make nomadic feeding movements.
