Human–bird relationships cover a spectrum of interactions. When species inhabit the same environment, they influence all other inhabitants of the ecosystem to a greater or lesser degree. At one end of the scale they may have had limited contact, although people likely have always noticed birds a...
We studied hourly variation in measures of the abundance of individual species and the species composition of bird assemblages in different habitats and seasons in the western Sierra Nevada of California, using 8- and 10-min point counts. Results failed to show clearly that any one of the first...

Salvage logging of fire-killed trees in western US conifer forests has been shown to negatively affect many wildlife species, but there are few quantitative studies from the Sierra Nevada, CA. Salvage intensity (i.e., the proportion of fire-killed trees removed during logging activities) has als...
