Abstract
ABSTRACT. The influence of landscape structure on abundance or spacing patterns of generalist bird species may be nonlinear and vary annually depending on the severity of environmental conditions. The Eastern Wild Turkey (Meleagris gallopavo sylvestris) is a generalist forest species that experiences high mortality when snow reduces food availability. Although increasing amounts of cornfield habitat may benefit Wild Turkeys by providing an alternate food source, reduced forest cover or elevated levels of forest fragmentation associated with increased corn (Zea mays) production could be detrimental. We evaluated the hypothesis that spring density of male Wild Turkeys increases with the amount of corn habitat as long as forest cover remains a dominant landscape component and that this increase is more prominent following a winter with thick snow accumulations. We performed point counts and corrected for imperfect detection in 2003 and 2004 at 130 randomly distributed sites in southern Quebec. After a mild w...
