The big story: tonight's migration
Heads up Illinois!

Tonight, as predicted, we've received favorable southerly winds. As a result, tonight's radar has lit up, showing moderate concentrations of birds seizing the opportunity of the strong tailwinds across the Prairie State. Reflecting between 10 and 20 decibels, what the radar is really showing is 71-227 birds per cubic kilometer of sky. There's a lot over our heads, folks. Excitingly, this is the most migration we've seen since April 1st, and as the night goes on, we may even top it. Here's hoping for that!

Tomorrow morning, arrivals and influxes should be of about the same magnitude anywhere in the state. So, regardless of where you are, if you can, hit your favorite patch! Established migrant traps especially should make for memorable birding tomorrow, but I encourage you to search out those less-birded places that still hold potential. And of course, eBird! What new species might you find tomorrow? Eastern Towhees, Blue-gray Gnatcatchers, Ruby-crowned Kinglet, Swamp, Chipping, and Savannah Sparrows, Brown Thrashers, American Bitterns, Chimney Swifts, Soras, Caspian Terns, Yellow-rumped Warblers, Green Herons, and Spotted Sandpipers might all be arriving/influxing. And those are just a few; to get a complete picture, I encourage you to read the latest BirdCast Regional Migration Forecast, and then to check our good ol' eBird page.

In addition to this good news, I'm happy to report that Sunday night should be just as favorable for migration. Southerly winds are forecast to continue into Monday morning. By Monday night, however, a front from northwest of us is forecast to bring unfavorable winds across the state. From there, we'll see what happens!

That's all for tonight, folks! Looking forward to seeing what's out there tomorrow morning.
