I studied northern saw-whet owl (Aegolius acadicus) nest productivity and survival in hybrid poplar (Populus spp.) plantations in eastern Oregon, USA. I placed twenty-five nest boxes in 2- to 5-yr-old plantations and monitored them during the 1999 nesting season. Nine nesting attempts were made and eight were successful. Daily survival rates for eggs and nestlings as estimated by the Mayfield method were 0.9919+or-0.0025. Clutch size, number of eggs hatched, and number of fledglings for all nesting attempts were 5.22+or-0.49, 4.33+or-0.69, and 3.55+or-0.60. Hybrid poplar plantations can provide suitable nesting habitat for northern saw-whet owls if nest boxes are provided.
