In our long-term study of Cooper's Hawks (Accipiter cooperii) in Wisconsin, we have found no evidence that habitat (i.e., urban vs. rural, conifer plantation vs. non-plantation nests, presumptive site quality as indexed by consistency of nesting area use and high breeding density) was related to indices of reproductive success, phenology, annual adult survival, production of recruits, or fitness (Rosenfield and Bielefeldt 1999, Rosenfield et al. 1995, 2000, 2009, 2013, 2015a). Rather, reproductive success of Wisconsin Cooper's Hawks was apparently related to intrinsic qualities of individuals. For example, body mass (i.e., size) of Cooper's Hawks ≥2 yr old of both sexes, which was also unrelated to nesting area habitat, was positively correlated to brood size and number of detected recruits; larger birds also tended to breed earlier in the year than smaller ones (Rosenfield and Bielefeldt 1999, Rosenfield et...
