The Northern Saw-whet Owl ( Aegolius acadicus ) (NSWO) is a mesopredator commonly found within upland ecosystems across North America. NSWO’s migrate in the fall from September to December, peaking around mid-October, making them relatively abundant in central Wisconsin during this time. Our project began in 2007 and continues to operate at Sandhill Wildlife Area in Babcock, WI, and we have captured over 1,300 NSWOs. These owls are captured using call-playback devices and mist nets. The birds are banded using USGS aluminum leg bands, contributing to national banding data on Northern Saw-whet Owls. Our project has previously focused on studying migration patterns and discovered that the migration pattern has shifted over the course of the project. We now want to determine if a relationship between migration timing and weather patterns exists. We will use our previous analysis to compare the shift in migration to the change in temperature using our historical data.
