Nothing in, nothing out


National overview

High pressure continued to dominate most of the US from the Rockies east to New England. Only the most southerly and westerly parts of the country were outside of the influence of strong high pressure and experienced some influx of new birds into this morning. See the individual radars below to remind yourself what “no migration” looks like… because that’s all about to change in a few days from now.

Nothing but a little ground clutter for Wisconsin. Birds were staying put.

Iowa & Illinois

And the same goes for Iowa and Illinois; No birds in the atmosphere last night.

I think the lack of birds on the radar says it all. Northerly flow and a return to some chilly temps kept all birds in their places last night. The forecast is shaping up for a moderate push of birds into the Midwest on Wednesday night followed by some much bigger pushes later in the weekend, but until this high pressure moves out I guess we’ll just have to spend our time scouring the birds that are already here… which is not a bad thing at all given the waterfowl and interesting shorebirds that have shown up over the last week (including the Reeve, which has turned out to be most likely a Ruff)

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

  1. From Commerce Twp., MI. (Detroit suburbs), I have had a Common Loon on Cooley Lake since Easter Sunday. The loon is still present, this morning. A few Bufflehead and a pair of Wood Ducks are on the lake. The Hooded Merganser, Ruddy Duck & Common Goldeneye have moved on. Nothing new in the yard.
