Shifting Songbirds


The Black-throated blue warbler (Dendroica caerulescens) is a common avian species at Hubbard Brook. HBR LTER.
Forest bird populations of northeastern North America are being increasingly affected by environmental challenges, including habitat loss and degradation, forest disturbances such as ice storms, atmospheric pollutants such as acid deposition, pathogens that enhance tree mortality and climate change. To develop conservation and management plans that might mitigate such impacts, a mechanistic understanding of the ecology of forest birds, specifically factors affecting their reproductive success, survival and recruitment is essential. Since 1969, Richard T. Holmes (Dartmouth College) and co-workers have been conducting research on the population and community ecology of birds inhabiting northern hardwoods forests within the Hubbard Brook Experimental Forest, New Hampshire, USA.
