The Hudsonian godwit population has declined by 95% in four decades due to environmental changes.
The UN Convention on the Conservation of Migratory Species (CMS) meeting in Brazil on March 23 proposed international protection for 42 species, including the Hudsonian godwit.
Migratory birds face "rapid and dramatic declines" due to climate change and habitat loss.
Hudsonian godwits travel 30,000 km annually from the Arctic to Patagonia.
Detailed Insights:
The Hudsonian godwit's decline is attributed to a combination of factors, including climate change affecting food availability in the Arctic and habitat disruption in the US and Chile.
Climate change has disrupted the timing of spring in the Arctic, creating a mismatch between chick hatching and insect availability.
Changes in farming practices in the United States have reduced the availability of shallow water wetlands, impacting the godwits' ability to find food.
Salmon and oyster farming in southern Chile have led to infrastructure development and human presence in intertidal zones, disrupting the godwits' feeding grounds.
The CMS meeting in Brazil addresses issues impacting migratory species, with participating countries legally obligated to protect listed species and their habitats.
The Pantanal region in Brazil, a biodiversity hotspot, is hosting the CMS meeting, highlighting the importance of wildlife conservation.
Key Concepts Involved:
Migratory Species: Animals that move from one habitat to another during different times of the year.
Habitat Loss: The destruction or degradation of natural environments, reducing the space and resources available for species to survive.
Climate Change: Long-term shifts in temperature and weather patterns, largely caused by human activities, impacting ecosystems globally.
