Abstract

Population trend analysis of American woodcook (Scolopax minor) using data from a singing-ground survey indicates population declines throughout the breeding range of the species between 1970 and 1988. In the eastern United States and Canada, this decline has been quite consistent throughout the period, but in the central portion of the continent the population increased during the 1970's and declined during the early 1980's. Observers differ in their ability to hear woodcock, and we document observer differences in the singing-ground survey data and incorporate them into our analyses. Habitat changes have been suggested as the most likely cause of declines in woodcock populations.
