Several nighttime radars showed considerable bird movement around 10PM Central, Sunday, April 11th.

The Quad Cities had the best bird signatures of all, kind of a big GLOB of birds moving northwesterly right smack dab over QC.

There was a strong influx of birds from the southeast on the Duluth, MN radar.

The Milwaukee, WI radar showed SSE-to-NNW activity up through the central part of the state of Wisconsin. It  also showed big clouds of pollution billowing out over Lake Michigan from both Chicago and Milwaukee, then getting picked up by the prevailing southerly wind over the water, and blowing north.

The Green Bay, WI radar showed very faint SE-to-NW signatures of birds moving up through the central part of the state, as well. Movement within +/- 50 miles of the lakeshore wasn’t evident, so it will be interesting to see if there was significant bird movement overnight or not.
