The Pacific flyway cuts through interior California and along the state’s coast, through habitat that has vastly changed after four years of severe drought and decades of water diversions. … As drought depletes the water supply in the Lower Klamath National Wildlife Refuge, migrating birds seek sustenance elsewhere.
What happens to birds during a drought?
Because of low precipitation and decreased water deliveries to wetlands and refuges, the birds face a reduction of breeding habitat. Less room to nest means reduced food resources and greater susceptibility to predators and stress.
Why is it important to have these wetland areas on the Pacific Flyway?
Wetlands provide critical wintering habitat for millions of migrating waterfowl, including geese and ducks. The open water and vegetation in wetlands provide food, rearing areas and cover for waterfowl and shorebirds. … Delta wetlands regularly harbor as much as 15 percent of the waterfowl on the Pacific Flyway.
