3.3 Cavities and SCB nesting success
Across all cavities found, whether a nest had been initiated in it or not, abandoned woodpecker cavities were significantly different than natural cavities: abandoned woodpecker cavities were built 42% higher in less decayed trees with 20% larger DBH than natural cavities and had 18% higher vegetation cover (Table 3). The size of the entrance hole and the depth of the cavity were not significantly different between nest types.
