Moment of Exodus via NexRad

This is it! Get your binoculars and hit the field! Clam to southerly winds produced the largest movement of birds thus far this fall over the Midwest and Ohio Valley:

Because it's relatively late in warbler migration, I doubt you'll find a lot of diversity. Wisconsin birders should look for Black-throated Green Warblers, Nashville, Tennessee, probably the first Orange-crowned Warblers, and of course, Palm and Yellow-rumped Warblers. Always be prepared for the stragglers, though. Naturally, White-throated and other sparrows should be on the increase soon. Bring on the Zonotrichia!


  1. I could hear it out of my window this morning.

  2. I've been watching the radar for a few weeks now and have noticed something. A couple of weeks ago I noticed the large light blue circle and then the arrival of warblers and small birds. The last few days the circle is just as large but a lot darker blue and then the arrival of Robins, Grackles, Red-wings, and Flickers which leads me to believe that the darker the circle the larger the birds. I've also noticed (here in south-central MN) a large number of flyovers of Canada Geese heading south.
