Yet, the total territory volume utilized by Red-eyed Vireos was inversely related to the density of caterpillars during this stage (i.e., when they would be needed as a food source to provision young), consistent with the food-value theory. I used the Information-Theoretic approach to develop 2 sets of a priori models. 0000006555 00000 n 0000004268 00000 n Less common bird species tended to be more selective foragers than the more abundant bird species. Daily survival rates of nests were negatively associated with basal area of red oak species (both Quercus velutina and Q. rubra) for several species individually and across the canopy-nesting guild. Partners also developed Habitat Management Guidelines that several state agencies are now implementing on state lands in the Appalachian Region. .Fp�`�&~Zk�?������֧����ApQW.\�d!��༼�IKu�� s�g�{.�̎� Many studies have compared songbird nesting success between forest edge and interior, but few have addressed potential factors underlying variation in nest predation pressure in relation to edge. Additional information may be found here about the Environmental Quality Incentives Program (EQIP) and the Regional Conservation Partnership Program . Increases in abundance and territory density were greater in stands with low pre-harvest densities (< 2 birds/ point or < 0.40 territory/ha) of Cerulean Warblers, whereas populations within stands with higher densities pre-harvest had minimal changes in abundance and territory density.

Service, Daniel Boone National Forest, Morehead, Kentucky, USA. Using science to restore habitat for declining species, Ecology, The Environment and Conservation. We suggest that in areas fragmented by agriculture, nest predator assemblages in forest edges may differ from those in forest interior. Conservation and management efforts directed toward establishing and protecting large tracts of mature forest, especially those on east-facing slopes, should be a reasonable approach to managing Cerulean Warbler populations in this area. Females and immature birds have greyer or greenish upperparts, a pale stripe over the eye, and no streaking on the back and no neck. Our primary objective was to relate change in abundance to topographic and vegetation metrics to evaluate the effectiveness of current Cerulean Warbler habitat management guidelines.
