Hudsonian Godwit: Long-Distance Migratory Bird in Decline

Context

The population of the Hudsonian Godwit has declined by nearly 95% over the past four decades, raising serious concerns about global environmental changes and habitat loss.

Q1. What is the Hudsonian Godwit?

1. It is a large migratory shorebird belonging to the sandpiper family (Scolopacidae).
2. Scientific name: Limosa haemastica
3. Known for its extraordinary long-distance migration ability.

Q2. What are its key features?

1. Appearance:
   1. Long legs and a slightly upturned bill
   2. Breeding season: gold, brown, and reddish (brick-red) plumage
   3. Non-breeding season: dull grey-brown colour
2. Diet:
   1. Feeds in shallow water
   2. Eats insects and crustaceans

Q3. Where is it found and how does it migrate?

1. Breeding habitat: Wetlands like sedge meadows and muskeg in sub-Arctic and boreal regions
2. Distribution: Found across North America and parts of South America
3. Migration: Travels from the Arctic to Patagonia (South America) every year and can fly up to 11,000 km non-stop without eating, drinking, or resting. (One of the longest continuous migrations among birds).

Q4. What are the major threats?

1. Habitat loss (wetlands degradation)
2. Climate change affecting breeding and feeding grounds
3. Changes across multiple countries along migration routes.
4. Due to this, it is listed as Vulnerable in the IUCN Red List.

Conclusion

The sharp decline of the Hudsonian Godwit highlights the need for international conservation efforts, as migratory species depend on multiple ecosystems across continents for survival.
