Agricultural fields may provide an important supplementary foraging habitat for whooping cranes (Grus americana) in the reintroduced Eastern Migratory Population (EMP). We developed methods and gathered preliminary data regarding whooping crane foraging efficiency and habitat use to better understand the use of agricultural fields by breeding cranes. We generated a simple null hypothesis that cranes would spend more time in the habitat type (wetlands vs. agricultural fields) in which they were able to obtain a higher foraging efficiency to maximize food intake, along with several alternative hypotheses pertaining to reasons cranes may prefer wetlands or agricultural fields during …
