Nest-site Selection and Nesting Success of Cavity-nesting Birds in High Elevation Forest Drainages
ABssAcr.-We identified habitat features that characterized successful and unsuccessful nest sites, nest sites vs. random sites, and differences among coexisting species of cavitynesting birds for 356 nests in central Arizona. Live and, more commonly, dead quaking aspens (Populus tremuloides) were used for 88% of all nest sites, but aspens constituted only 12% of all trees in random plots (n = 1...
متن کاملEffects of Prescribed Burns on Wintering Cavity-Nesting Birds
Primary cavity-nesting birds play a critical role in forest ecosystems by excavating cavities later used by other birds and mammals as nesting or roosting sites. Several species of cavity-nesting birds are non-migratory residents and consequently subject to winter conditions. We conducted winter bird counts from 1998 to 2000 to examine the abundance and habitat association of cavity-nesting bir...
متن کاملEndophagy of biting midges attacking cavity-nesting birds.
Feeding behaviour, host preferences and the spectrum of available hosts determine the role of vectors in pathogen transmission. Feeding preferences of blood-feeding Diptera depend on, among others factors, the willingness of flies to attack their hosts either in the open (exophagy) or in enclosed places (endophagy). As far as ornithophilic blood-feeding Diptera are concerned, the biting midges ...
متن کاملThe Effects of Postfire Salvage Logging on Cavity-nesting Birds
We investigated the effects of postfire salvage logging on cavity-nesting birds by comparing nest densities and patterns of nest reuse over a three-year period in seven logged and eight unlogged patches of mixed-conifer forest in the Blackfoot-Clearwater Wildlife Management Area, Montana. We found 563 active nests of 18 cavity-nesting birds; all species were found nesting in the uncut burned fo...
متن کاملUse of Arbutus menziesii by Cavity-nesting Birds
As part of a larger study of wildlife habitat associations in Douglas-fir (Pseudotsuga menziesii) forests of northwestern California, I recorded characteristics of nest sites used by 16 species of cavity-nesting birds. Pacific madrone (Arbutus menziesii) contributed only 8% of the basal area of the stands I studied, but 24% of all cavity nests were in madrone. Although nests were distributed am...
