More birds up through the Midwest

National Overview

Sorry for the late post; I’m a bit under the weather this morning. If you’ve been following along the past two mornings you know the frontal boundary moving east out of the Plains has been the main trigger for widespread migration up through the middle of the country. High pressure over the eastern seaboard has broken things up a bit, with only the die-hard birds continuing to push north near the coast.

Since I will be publishing “as I go” each morning you may see some incomplete posts throughout the early morning hours. Don’t worry- it’s coming!

Sub-optimal conditions, you say? Yes! But birds are chomping at the bit to go right now- and migration was still apparent over the Mid Atlantic with birds appearing to head WNW on easterly winds last night. Along the Delaware River should be best today, but don’t expect any major concentrations as migration was light.

Upper Midwest

Migration was big and widespread across IA and IL with most birds heading more NNE today than yesterday. This will bring more birds into southern WI this morning, and along the Lake Michigan eastern shore as well.

A nice late-spring flight across the region with birds heading NNE. Lots of birds moving with most of them dispersed across the landscape by morning, so hit the spring migrant traps throughout the state today. A more NE trajectory means opportunity for those along the lakeshore according to the Milwaukee and Green Bay radars. Get out and bird on this summery Saturday! I should also note that there was a big push into the Superior WI/ Duluth MN region last night, and precipitation appears to have pinned some birds against the lakeshore. Birders in the Duluth/Superior area should be thinking about a Big Day today… (maybe ? 😉 )

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.
