Some birds that attempt to nest in habitats such as conifer plantations may experience lower reproductive success and diminished fitness in comparison to conspecifics in other habitats, rendering such habitats sinks or ecological traps. We did not detect significant differences between conifer plantation and non-plantation nests in terms of clutch size, number of bandable young per nest, or nest success for Cooper's Hawks (Accipiter cooperii) in Wisconsin during 1980–1998. Pine plantations contributed recruits to subsequent breeding generations in proportion to their productivity of bandable nestlings. Conifer plantations in Wisconsin also contained nesting densities and productivity indices for Cooper's Hawks that are among the highest reported for the species. Thus, conifer plantations in Wisconsin are neither ecological traps nor population sinks for nesting Cooper's Hawks.
