This page (currently displaying data for Champaign, IL) shows the probability of a species appearing on a checklist during a given month. The change in probability from the previous month is also shown, to highlight which birds are coming and going. Rows with significant changes (< 0.5x or > 2x) are highlighted in red or green. This is based on historical data from eBird, and does not include the current month.
