Characterization of Habitat Used by Whooping Cranes during Migration

摘要

Information is drawn from the literature and the professional opinions of behaviorists and habitat use experts, and used to describe requirements of whooping cranes (Grus americana) during migration. Migration strategies of North American cranes are compared and inferences drawn. The requirements for usable food and cover are examined and described quantitatively for evaluations that focus on roosting habitat. When possible, information is presented in terms of both traditional and nontraditional stopover areas. Site-specific evaluation criteria address issues of visibility, water depth, wetland size, and disturbance; suitability relations are presented for each habitat component.
