Songbird surveys , 1952 - 1964, 1983 - 2008 Adirondack Long-Term Ecological Monitoring Program Project No. 2 Breeding Birds by Adirondack Ecological Center of the State University of New York College of Environmental Science and Forestry, Newcomb, New York. Environmental Data Initiative.

Study objectives were to (1) Document long-term trends in relative
abundance and diversity of breeding forest birds (songbirds) in forest
stands with different harvest histories and (2) Identify bird species
that can be used as indicators of habitat change or degradation.
Declines in neotropical migrants have been linked to changes in
habitat quantity and quality across species' range. Songbirds that
nest and forage in different habitat types or at different heights in
the forest canopy may not be affected equally by forest change or
management. We detected breeding songbirds using point-counts at
Huntington Wildlife Forest (HWF) in the central Adirondack Mountains
of New York during 1983-2000 and modeled on an original songbird point
count dataset from Webb et al. (1977). Relative abundance (RA, the
number of individual birds/count) was measured in sites with differing
management histories, from an unmanaged >300-year-old stand to a
stand cut with the shelterwood/overstory removal method just prior to
sampling in 1983). Over eighty bird species were detected during the
study duration. Songbird ecology and habitat characteristics can be
used to understand long-term changes in relative abundance as related
to forest change.
