Fronts stacked up and filled with birds

National overview

Check out the three fronts stacked up across the Midwest! And between each cookie layer there’s a heaping filling of sweet migrant goodness. Migration was heaviest across the Upper Midwest and down through the Central U.S. with only the Northeastern U.S. neglected due to poor conditions last night. That will change as these fronts move through and cooler air brings birds down from the Boreal breeding grounds over the next few days. Fallout potential is best along the precipitous frontal boundaries while otherwise widespread movement will bring new birds to migrant traps across the U.S. this morning. No time to do the individual radars today, so go ahead and take a stab at them yourselves; besides, you all know what you’re doing by now!!! :)

Northeast winds over much of the Upper Midwest kept birds down once again. Little-to-no migration evident over either Duluth or the Twin Cities radar stations. Expect birding conditions to be consistent from yesterday.

  1. Thank you for what you do! We are new to birding and this is so incredibly helpful!

    Hooray! They are coming!

    I’ll be out in the morning looking for new arrivals. Looks like a good night shaping up on the Duluth radar. Found a stunned window strike Tennessee Warbler this afternoon.

    There weren’t many warblers around Grand Rapids, but new arrivals included Horned Larks, American Pipits, and Lapland Longspurs. Fall sparrows like White-crowned and Lincoln’s are picking up a little.
