SORA DAWN: An energetic dawn chorus in a prairie pothole marsh, recorded 17 May 1993 near Chase Lake National Wildlife Refuge in central North Dakota.
AT SUNRISE, I visit a prairie marsh edged with thick cattails and rushes. The marsh is alive with sound. I hear the reedy songs of Marsh Wrens, the hollow on-ka-chonks of American Bitterns, and the whinny-like outbursts of Sora rails. Red-winged Blackbirds pipe their conk-la-rees and a Willet flies about in the sky, repeating his whistled pill-will-willet and eventually passing overhead. Ducks abound, flying, landing and splashing. I hear the loud bek! of Gadwall and the raspy chux of Shoveler. An Avocet flies in, giving loud wheet calls as he lands. What an amazing profusion of sound! Imagine living next to this marsh, thoroughly awash in natural sounds both day and night from early spring through the autumn migration.
