【 摘 要 】

The primary objective of this study was to experimentally test the hypothesis that a positive correlation exists between weight of accipters and the weight of their prey.Sharp-shinned hawks (Accipiter striatus) and northern goshawks (A. gentilis) were selected for the study due to their abundance during migration, ease of trappings, and differences in weight.
