Table 2: Model averaged estimates with 95% confidence intervals (CI) for variables retained in the candidate model sets that predicted cavity nesting bird nesting success. All continuous variables used to create candidate models were z-scaled. Decay was ranked 1 = live tree, 7 = dead, decayed tree. Cavity Type = whether the nest was located in an abandoned woodpecker cavity or a naturally occurring one, DBH = diameter of the nesting tree at breast height. Flycatchers = combined observations of Ash-throated and Brown-crested flycatchers. Data was collected on the San Antonio Viejo Ranch, East Foundation in south Texas during the summer of 2019.
