ABSTRACT:
This dataset provides counts of potential nest predators recorded on surveys conducted in black-throated blue warbler territories at the Hubbard Brook Experimental Forest. Surveys occurred on three gridded study plots at the HBEF: low elevation (250-350 m; 85 ha), middle elevation (450-600 m; 65 ha), and high elevation (750-850 m; 35 ha). See Rodenhouse et al. 2003 for plot details.

LOCATION DESCRIPTION
Predator surveys occurred on three gridded study plots at the HBEF: low elevation (250-350 m; 85 ha), middle elevation (450-600 m; 65 ha), and high elevation (750-850 m; 35 ha). See Rodenhouse et al. 2003 for plot details.
SAMPLING DESIGN
Nest predator abundance was quantified by conducting four 5-min point counts of diurnally active predators (primarily eastern chipmunks Tamias striatus, red squirrels Tamiasciurus hudsonicus, and blue jays Cyanocitta cristata) during each of four biweekly periods from late May - July (n = 16 surveys / territory / year).
