The Yukon Kuskokwim Delta supports one of the largest populations of geese in the world. Elders recall so many geese passing overhead, blocking out the sun and making a thundering noise. The ponds, lakes, streams and marshy coast is perfect habitat for raising young birds. Birds must eat a large amount of food in order to refuel from a long spring migration, raise their young, and prepare for fall migration. Alaska wetlands provide a rich source of food for migrating birds. The birds that arrive in the spring provide important food for Yupik communities.
“When long, hard winters emptied the people’s food caches too early, starvation loomed. Return of geese in April (Tengmiirvik) helped to save us. –Chuck Hunt, born & raised on the Y-K Delta “
