From 1979 to 1984, a type of two-age harvest was applied
to mature, second-growth Appalachian hardwood forest
stands (Miller et al., 2006). Duguay et al. (2001) examined
breeding bird abundance and nest survival from 1993 to
1996 in these two-age stands, similarly-aged clearcuts, and
unharvested stands. We used these stands to investigate
long-term breeding bird population response to clearcuts
and two-age harvests to determine whether two-age management
contributes to conservation of mature-forest and earlysuccessional
breeding birds. In 2005–2006, bird surveys were
conducted in 19–26 year-old harvests and unharvested mature
forest stands surveyed by Duguay et al. (2001) and in
young stands 6–10 years post-harvest. The study objectives
were to (1) compare breeding bird relative abundance and
species composition among treatments in 2005–2006 and (2)
examine temporal changes in the bird community by comparing
current data to the data collected in 1994–1996 in the old
harvests and mature forest
