Summary of different species or groups detected at 168 nest platforms monitored by remote cameras for up to 177 weeks (670 ± 264 days; $\overline{x}$ ± SD) at 23 young forest sites in the central Oregon Coast Range, Oregon, USA. Italics indicate species that represent a subset of a taxonomic group. Data represent weekly detections (No. of detections per week) during the sampling period in which each nest platform was monitored (n = 15,510 monitoring‐weeks). Predation rate is the proportion of detections resulting in an observed mortality of a red tree vole attributable to a given nest predator.

^aData include only weeks in which a species or group was detected such that no 0 values were included. $\overline{x}$ ± 1 SD.

^bNorthern saw‐whet owl (n = 20), Western screech owl (n = 9), Northern pygmy owl (n = 9), Unidentified small owl (n = 17).
