Pacific Northwest Laboratory conducted a study for the US Department of the Army on long-billed curlews (Numenius americanus) on the Yakima Training Center (YTC) in the spring and summer of 1993. Long-billed curlews are a Class IIIc federal candidate species and are listed as a ``species of special concern`` by the Washington Department of Wildlife. The objectives of this study were to (1) locate major nesting areas, (2) locate brood rearing areas, (3) evaluate habitat requirements, (4) determine diet, (5) evaluate response to troop activities, (6) estimate population size, (7) estimate recruitment rates, and (8) establish a relative abundance survey method.
