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 models revealed that [...]
