Migration: Snow Overlay
Using our interactive mapping tool, you can view the status of woodcock locations for a specific range of dates by toggling the slider below. During periods of major migration in the Fall (Oct 15-Dec 15) and Spring (Mar 1 through mid-May) we update the database regularly, but given transmitter upload frequencies we expect about a +/- 3-day precision on our location data. Learn more about how our transmitter technology functions on our research page.
Snow overlay data is from the National Oceanic and Atmospheric Administration and updates daily. The snow line is typically the northernmost extent to which birds will move during that stage of spring migration. Snow overlay is from the most recent date and will not change with the date range slider.
