The abundant wetlands in America's Arctic, especially those concentrated around Teshekpuk Lake, are among the most extensive and productive for birdlife in the entire Arctic. Birds fan out across this landscape to nest in astonishing numbers, with some of the highest known densities of breeding shorebirds anywhere on earth. The Teshekpuk Wetlands provide vast tracts of undisturbed habitat and an abundance of food. Summer produces an explosion of insect life and plant growth, and 24 hours of daylight provides the opportunity to feed around the clock. The abundant resources fuel a short but rapid reproductive season, drawing millions of birds from around the world year after year.
