Birds stalled to our south due to storms

Birds stalled to our south due to storms

National overview

As with yesterday, a stationary front draped across the US represents the boundary between migration and none. North winds and precipitation to the north of the boundary are keeping birds grounded, while southerly winds to the south of the boundary area bringing them into the Midwest. I’m on my way to Texas this morning to take advantage of some of that activity while I help out my buddy Jeff Bouton at the Leica booth. If you’re down there, make sure to stop by as we’ll be doing some live migration forecasting from the booth, and hopefully witnessing some coastal fallout first-hand. I’ve posted the radar loops below but don’t get too excited… there wasn’t much in terms of migration over our area.

Nothing much going on in our region last night with northerly flow dominating most of the forecast area. The only exception was IA and IL where some birds were heading north. We’ll have to wait for this front to push out to the east later this week before we see any significant influx of birds.

As always, woodcreeper.com depends on you to report your sightings and be our ‘eyes on the ground’, so please come back and give us an idea of how we’re doing predicting birding conditions in your neck of the woods.

Good Birding,

David
