Black-throated Green Warbler (Dendroica virens) Science Article 2
abstract
Black-throated Green Warblers (Dendroica virens) use coniferous vegetation as foraging and perching substrates at coastal sites in Maine and predominantly deciduous vegetation at inland sites in interior New Hampshire, despite the availability of both substrates. I tested the hypothesis that these habitat use patterns result from intrinsic preferences.
