GELLERMAN: Splish, splash, they’re taking a bath. Migrating birds take a quick dip at the watering holes in south-central Nebraska and then they’ll continue to wing it along the Central Flyway. BirdNote®’s Michael Stein has more.

STEIN: For 20,000 years, spring rains and melting snow have filled the playas of the Rainwater Basin of south-central Nebraska. Carved by glacial winds at the end of the last Ice Age, the playas are shallow depressions the warmth of spring fills with abundant life.

STEIN: As winter ends, ten million waterfowl rest and feed here before continuing north.

STEIN: The seasonal wetlands of the Rainwater Basin form a 150-mile-wide funnel for waterbirds migrating from the Gulf Coast and points south to northern breeding grounds. The basin is the narrowest neck of the great migratory route we call the Central Flyway.

STEIN: In recent years, the number of Snow Geese stopping in the region during spring has risen dramatically to more than three million birds. A third of North America’s Northern Pintails rely on the food-rich habitat here.

STEIN: Shorebirds of 27 species use the wetlands. So do half a million Sandhill Cranes.

STEIN: The importance of the region’s wetlands for waterfowl cannot be overstated. Fat reserves acquired during their stay here can mean the difference between success and failure in nesting. No other stopover between wintering and nesting grounds can replace the combination of wetlands and grain fields found in the Rainwater Basin.

STEIN: I’m Michael Stein.
