3.2 GFWO nest success
The mean height for a GFWO cavity within our study was 2.3 m ± 0.26, the
mean DBH of the nesting tree was 52 cm ± 6.2, the mean cavity diameter
was 9 cm ± 0.8, the mean depth was 7 cm ± 0.7, and the mean vegetation
cover was 43% ± 6.3. Over 25% of GFWO nests were in trees with decay
class 1 (Table 1).
Table 1: Nesting tree decay (1 = live tree, 7 = dead, decayed
tree), for each cavity nesting bird found within the study. Count and
percent of that species within each decay rank are shown for each
species of secondary cavity nesting bird, along with the primary cavity
nesting bird, the Golden-fronted woodpecker. The data on the
Ash-throated and Brown-crested Flycatchers were combined due to similar
life history traits between species. Data was collected on the San
Antonio Viejo Ranch, East Foundation in south Texas during the summer of
2019.
