Western bluebird (Sialia mexicana) population data were collected in northern Arizona, USA, following two wildfires (Hochderferr Fire, Horseshoe Fire) that occurred in May and June 1996. This is a data subset consisting of 8 years of bird data collection post-wildfire (1999-2006) and 3 years of vegetation data (2002, 2005, 2006), and is part of a larger long-term data set. Data consist of detection/non-detection data from point counts, adult banding data collecting at mist-nets and nest surveys, habitat covariates (live tree basal area, snag basal area, burn severity), and sampling covariates (time since fire, transect line, point-count data observer, sex of banded adult bird).
