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.
