Breeding Distribution and Habitat Pref. Erence of the Gray Vireo in Nevada
نویسنده
چکیده
In the northern portion of the breeding range of the Gray Vireo (Vireo vicinior) in Nevada, published records of occurrence are based on seven specimens from four localities and sight records from an additional five stations scattered over southern Nye, southern Lincoln, and Clark counties (Linsdale, 1936; Miller, 1946; Gullion et al., 1959; Hayward et al., 1963; and Johnson, 1965). The present note summarizes the aforementioned records and adds new informa-

Effects of Conifers on Aspen-breeding Bird Communities in the Sierra Nevada
We examined bird-habitat relationships within and across a range of aspen habitats in four major watersheds in the eastern Sierra Nevada mountains of California and Nevada to identify habitat features of importance to aspen-breeding birds. Using point counts and vegetation assessments from 462 individual stations between 2001 and 2003 allowed us to investigate important habitat features at wate...
متن کاملRiparian Forest as Habitat for the Least
--Data are presented on vegetation structure in Least Bell's Vireo (Vireo bellii pusillus) breeding habitats. A discussion of vegetation and several o"ther fac tors relevant to breeding success of this endangered species is presented. Recommendations are made for actions to en sure the future of the subspecies as a breeding inhabitant of riparian forests.
متن کاملCharacteristics of Least Bell's Vireo Nest Sites Along
Due primarily to alteration ofriparian vegetation and nest parasitism by brown-headed cowbirds (Molothrus ater). the least Bell's vireo (Vireo bellii pusillus) has under gone a tremendous decline in range and numbers since the 1920's. In 1987. we sampled vegetation at 32 nest sites to characterize nesting habitat ofleast Bell's vireos in the Santa Ynez River drainage. Most next (59.4%) were lo...
متن کاملAbundance and Productivity of Warbling Vireos across an Elevational Gradient in the Sierra Nevada
Recent studies have shown that Warbling Vireos (Vireo gilvus) are declining in California and that these trends are due to low reproductive success. Brood parasitism by Brown-headed Cowbirds (Molothrus ater) has been implicated in the low productivity. I explored two hypotheses related to population dynamics of Warbling Vireos along an elevational gradient: (1) potential source populations exis...
متن کاملHabitat Selection by Juvenile Black-Capped Vireos Following Independence from Parental Care
If differences in ecological requirements result in juvenile birds using different habitats from breeding birds, then habitat management to protect those birds must protect both breeding and postbreeding habitats. We examined habitat selection by juvenile black-capped vireos (Vireo atricapilla) following their independence from parental care, in 2010–2013 on Fort Hood Military Reservation in ce...
