Temporal and spatial variation in habitat quality: Breeding ecology of the chestnut-backed chickadee in uncut and partial cut forests in British Columbia I examined how partial cutting influenced the use and selection of habitat by chestnut-backed chickadees (Poecile rufescens ). My objectives were: (1) to examine the variability of nest survival and identify the contributions of year, harvest treatment and habitat characteristics, and predator activity at 3 spatial scales, (2) to compare use and selection of nesting habitat in uncut, partial cut-mature, and partial cut-old sites at 3 spatial scales, and (3) to identify the influence of habitat structure or annual differences in food abundance and predation pressure on reproductive output. I found that nest predation rates fluctuated between years: 56% in 2000, 64% in 2001, 10% in 2002, and 12% in 2003. Survival...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
