Sept 20, 2015: Widespread Movement
Due to light northerly winds across ALL parts of Illinois tonight, Illinois is experiencing WIDESPREAD MODERATE to HEAVY migration, which can be seen on the current national composite radar: (http://tempest.aos.wisc.edu/radar/us3comp.gif)
So I strongly encourage birders in all areas of the state to get out and go birding tomorrow (Sunday) morning. Looking ahead to tomorrow night, it appears that northern areas of the state will be receiving southerly headwinds and therefore little migration will occur there, while southern areas will receive northerly tailwinds which could cause a larger turnover in southern Illinois; however, it will more likely cause a phenomenon where birds moving out of the state will not be replenished by influxes from the north, meaning Monday morning should be much less productive than tomorrow across most of the state.
Liz Day Shorebird Forecast: Late-migration shorebird targets for Illinois include American Golden-Plover, Greater Yellowlegs, Stilt Sandpiper, both (or one?) Dowitchers, and Wilson's Snipe. Look for the Golden Plover in sod farm habitats, Snipe in overgrown wetland areas, and all others in mudflat and other wetland areas.

Go birding tomorrow (Sunday) morning!
