Migration tonight

There appears to be a fairly good migration movement tonight. Below is an image from doppler radar that shows lots of action in the Mississippi River Valley.

Tracking migration with radar has been done for years but now with everyone having access to nexrad data on the Internet it's a nice tool to have for anticipating what might show up in your yard in the morning. The best thing to see is lots of "green donuts" spread all across the U.S.. That's when the "wave" of birds arrive. Sunday morning should be busy in your backyard!

I was out and about here in North Jersey today. Not much happening. It was cold and the wind was from the north. Lots of ducks around on the reservoirs though.
