An open window into the world of birds as
they fly through the great lakes region
Birds' instinct to migrate is often influenced by shifts in temperature, available daylight, moon phases and strong tail winds. Like air quality and UV reports, the FLAP Tracker is a Bird Migration Intensity report that alerts you to the concentration of birds as they fly through your region. Alert levels are determined by a compilation of indicators displayed on this webpage. Turning lights out at night and treating windows during the day is imperative to reduce the threat of bird/building collisions, especially during Heavy to Extreme Intensity alerts. Please participate in our citizen-science project; keep your eyes peeled for birds that have collided with windows and report these events on the FLAP Mapper.
