How to read it
Each county, and each bar on a bird's page, is the share of complete checklists in that place and week that listed the bird. It is the chance that a birder looking there will list it, not a count of birds. Grey means too few checklists to say anything. Methods and limits.
The pages are free. The app adds your own life list and trip planning; pricing never turns into a subscription. Guides: the blog.
