In the 1960’s the invasive Hemlock Woolly Adelgid (Adelges tsugae [hereafter, HWA]) began to spread west across the hemlock stands of the Eastern U.S. killing a significant number of Eastern Hemlock (Tsuga canadensis). While chemical treatments, primarily with the active ingredient imidacloprid, have been implemented, their effects on hemlock dependent avian species are largely unknown. A 2009 study, which took place as HWA was beginning to invade Kentucky, identified six indicator species that were positively and negatively correlated with eastern hemlock stands throughout the Appalachian Mountain region of Kentucky. Our study repeated bird and vegetation surveys at the same 65 …
