Reproductive maturation and breeding of woodcock in North Carolina Reproductive maturation and breeding of woodcock in North Carolina
Breeding woodcock (PhiJohela minor) were studied in North Carolina during the winters and springs of 1974-75 and 1975-76.. Measurements of testes and ovaries from 19 male and 30 female woodcock suggest that gonadal recrudescence in many woodcock occurs on the wintering grounds.

Researchers used banding, localized studies, aerial surveys, and pesticide analyses to identify factors influencing regional populations. Declining populations showed extremely poor production, contamination...
