Abstract
- The offspring sex ratios for Cooper's Hawk were determined at 372 nests throughout Wisconsin from 1980 to 1995. The results revealed no significant differences in sex ratios at fertilization and at the nestling stage. However, the males were significantly more numerous at both stages, indicating that sex ratios at the fertilization and nestling stages were skewed toward males.
