TLBO has been operating a fall migration monitoring program since 2006. The focus of our efforts is on migratory songbirds but all species detected get recorded as part of our Daily Estimated Totals. In 2011 we started a Northern Saw-whet Owl banding program that operates ~7-12 nights a season, depending on weather. The TLBO is located in the stunning Tatlayoko Valley, nestled in the interior side of the Coast Mountains in the Chilcotin region of British Columbia, Canada. The valley and the Homathko River drainage to the south, are one of just three corridors linking the interior and coast of BC creating an interesting scenario for migration as some species clearly use the valley as a migratory corridor (see recaptures of TLBO-banded NSWO from Vancouver Island) while others appear to enter the valley by "mistatke" resulting in regular northward daytime passages of passerines (pers. obs) during fall migration. Originally started by the Nature Conservancy of Canada, the bird observatory now operates under BC Spaces for Nature.
