Figure 5 . Monthly patterns of nest platforms use (proportion of
nest platforms with detections) by several vertebrate species in young
forests in the central Coast Range, Oregon. We separated detections of
tree voles by age class (adult: tree.vole and juvenile). We defined
bird.dig as an event whereby a bird turned over nest material at the
nest for >3 minutes. Vertical gray boxes indicate the wet
season in western Oregon (November 1– April 1). We observed strong
seasonal patterns of birds digging and noted an increase in late wet
season 2018 coinciding with an increase in weasel (Mustela
erminea or M. frenata ) detections. Note: tree vole age classes
were only assessed for photos later than June 2016 and we truncated the
data to reflect this.
