Nestling feeding data from Black-throated Blue Warbler nests, Hubbard Brook Experimental Forest, 1997 - 2010

This dataset provides nestling feeding data recorded by video
cameras placed near black-throated blue warbler nests at the
Hubbard Brook Experimental Forest. We used camouflaged video
cameras mounted on a tripod at nest height but about 10 m
distant from the nest. We transcribed videos starting 10 min
after recording began to avoid any initial parental response to
the presence of the video camera. During each adult visit to the
nest, we confirmed the feeding parent’s color bands and recorded
its arrival time. We calculated the number of provisioning
visits to the nest per hour (“provisioning rate”) for males and
females separately, and standardized for differences in brood
size by dividing provisioning rate by brood size. Nests were
monitored 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.
