Seasonal Report Counts

This chart represents the cumulative number of sightings reported to the MOU on-line seasonal reportn for a specific date.

Choose a bird species from the select box on the right. This will trigger the generation of a chart, though there may be a delay while the map is created and sent to your browser.

This data is influenced by several factors, including the number of birders in the field, the number of birders reporting their observations, and the manner in which observational data is reported. It cannot, therefore, be considered representative of the actual number of birds in the state at any specific time.

The shaded areas represent the average early/late migration dates calculated by Paul Budde, red for the South and blue for the north. Click in the shaded areas to determine the exact dates. The charts can be zoomed in time by dragging the cursor over a section of time.
