Long-Billed Curlew Welfare: Wintering on the US Pacific Coast

Long-billed curlews wintering on Pacific Coast estuaries and grasslands face welfare threats from habitat loss and disturbance at key foraging sites.

Key Facts

Long-billed curlews are North America's largest shorebird with bills up to 20cm long
They breed in western grasslands and winter on coastal estuaries and agricultural fields
Estuarine habitat loss from urban development reduces wintering food availability
Agricultural disturbance on wintering fields causes energetic costs from repeated flushing
Their long bill is specialised for extracting crabs and invertebrates from deep substrate

Welfare Considerations

Long-billed curlews on degraded estuarine wintering habitat face reduced invertebrate prey availability when coastal development and pollution impair mudflat productivity. Birds forced to forage on agricultural fields face frequent disturbance from farm operations requiring repeated energetically costly flights. Dogs disturbing flocks cause unnecessary energetic expenditure reducing body condition. The specialised feeding technique requiring undisturbed access to mudflat substrate makes curlew welfare particularly sensitive to foraging site quality and disturbance frequency.

What You Can Do

Support Pacific Coast estuarine conservation protecting long-billed curlew foraging habitat
Keep dogs under control in areas where curlews are known to forage in winter
Report long-billed curlew flocks to eBird to contribute to wintering distribution monitoring
Donate to Manomet and other organisations protecting shorebird wintering habitats
Advocate for estuarine protection in coastal planning decisions
