Bark thickness and bark complexity varied (P 0.001) between host and non-host trees. Furthermore, when trees were classified into DBH size classes, trees 12 in and

DOWNLOAD EBOOKAs use of our forests intensifies, we foresters are paying more and more attention to the agents that damage trees. Much attention has been paid to fire, insects, and diseases. Now we are becoming more concerned about the damage done by animals and birds. One bird that draws our attention is the yellow-bellied sapsucker. This sapsucker (Sphyrapicus varius varius L.) is a member of the American woodpecker family. It attacks trees to feed on the sap and bark tissues (fig. 1). Its attacks can kill the tree or seriously degrade the wood. To learn more about this bird, the damage it does, its habitat, and its ecology, the Northeastern Forest Experiment Station has made a 5-year series of observational studies of this sapsucker and its behavior and feeding habits in our New England forests.

DOWNLOAD EBOOKThe purpose of this study is to provide a habitat analysis of the Yellow-bellied Sapsucker, Sphyrapicus varius, in the Southern Appalachians. This population of S. varius is unique because it breeds in the high elevations of the Southern Appalachians, while the northern population breeds from Pennsylvania to Alberta Canada. Albert Ganier described this population in 1954 (Ganier 1954). Using the Relevee method of habitat analysis I have described the territories of several breeding pairs in the Southern Appalachians. This analysis suggests that these birds require an open canopy of northern hardwood forest with some type of open area as a part of their territory. I have measured several other factors of the habitat as well. The information obtained in this study will be used to guide management practices to maintain and increase the population size of S. varius ssp. appalachiensis.
