Birds continue to move up through the middle of the U.S. and taper off in the east

National Overview

A strong migration signal was apparent across the middle of the US from Texas to Minnesota as a series of surface lows make their way east across the Great Plains. Southerly flow along these fronts created the optimal migration weather which continued eastward to the Great Lakes and decreased to the East Coast where high pressure has once again set up northerly flow.

Things were slow across the Mid Atlantic, especially along the coast. Washington D.C. showed the strongest flight across the region while the Carolinas were relatively quiet and NJ and DE experienced only a light flight. Most of these birds were heading due north, so I expect most birds to be distributed across the landscape today. Hit the interior ridges for the best bets at bird concentrations… although breeding birds and shorebirds are in, so why not go check them out while keeping an eye out for migrants?

With migration conditions improving every night now, birds are beginning to move into the region again. Last night we saw moderate migration across both IA and IL with most birds heading due north, if not a little NE, on SSW winds. Expect some shuffling of the deck across the board as new birds replace old ones in their march northward. We should be seeing more thrushes this morning as well as some of the later warblers such as Connecticut- so if you know their typical migratory haunts, check them out today!

As above, migration conditions have improved and more birds should be in the system today. With widespread migration across the state last night expect new birds throughout. With the trajectory of migration being S->N expect birds to be well distributed across the landscape- so hit the tried and true spring migrant traps this morning! One exception might be around Superior/Duluth since many birds appeared to be pushing up to the west end of Lake Superior this morning. Also west of the Door Peninsula, around Oconto and points north, should see some concentrations this morning.

    1 Parula at work, 1 Redstart at my house – checked your radar – looked like might be some new stuff scattered around, so went out locally – slow, but new stuff scattered around! I hit a place north of Wheelabrator – close to my house.
    1 Gray-cheeked Thrush
    1 Canada Warbler
    1 Blackburnian Warbler
    2 Redstarts
    1 Blackpoll
    And I missed a few chip notes.

    Kickapoo Valley Reserve, 6:53 a.m. to 9:20 a.m.
    No new migrants today, except for one distant Nashville. Redstarts, Yellow Warblers, Com. Yellowthroats, one Blue-winged Warbler. I was there on Wednesday, very few migrant warblers; did see one Wilson’s Warbler.
