Susitna Flats State Game Refuge - Birds

Birds

Perhaps the most spectacular feature of the Susitna Flats State Game Refuge — and certainly the prime reason for its refuge status — is the spring and fall concentration of migrating waterfowl and shorebirds. Usually by mid-April, mallards, pintails, and Canada geese are present in large numbers. Peak densities are reached in early May when as many as 100,000 waterfowl are using the refuge to feed, rest, and conduct their final courtship prior to nesting. The refuge also hosts several thousand lesser sandhill cranes and upwards of 8,000 swans. Northern phalaropes, dowitchers, godwits, whimbrels, snipe, yellowlegs, sandpipers, plovers, and dunlin are among the most abundant of shorebirds. Most of the ducks, geese, and shorebirds move north or west to nest in other areas of the state. About 10,000 ducks — mostly mallards, pintails, and green-winged teal — remain to nest in the coastal fringe of marsh ponds and sedge meadows found in the refuge. Recently, Tule geese, a subspecies of the greater white-fronted goose, have been discovered to nest and stage on Susitna Flats. In the fall, migrant waterfowl and shorebirds once again arrive in growing numbers to rest and feed on sedge meadows, marshes, and intertidal mud flats.
