Heavy migration into the Midwest; a good push up through the Northeast as well

National Overview

No time to post right now, but wanted to get the word out that there was some moderate to heavy migration from the Central US all the way to the East Coast. Click on the individual radar thumbnails below for the animated loops.

Spring 2012 Early Wrapup

Here we are in late May and birds continue to push north to the breeding grounds while the earliest arrivals sit on eggs or even feed the recently hatched. We should still see migration on the NEXRAD radar network into early June, but expect things to slow down over the next week. On that note, I’m getting to a few deadlines that require my undivided attention and so after today I’m going to suspend my daily posts to www.woodcreeper.com in an effort to complete these projects. If I see any major flights going on over the Mid Atlantic or the Upper Midwest I’ll be sure to ‘tweet’ it out on Twitter (@woodcreeper) and possibly get it out to www.woodcreeper.com if time allows- so be sure to follow me on Twitter to keep updated! I will also work on summarizing this spring for a later post this summer so stay tuned.
If you found www.woodcreeper.com useful this spring, I urge you to consider becoming a supporter of the site (click here for the details). Currently the online archive stands at roughly 9 Gigabytes which is pretty huge considering how many people access it (almost 10 years of archived radar, my interpretations, and your ground-truthing, accessed by 500 – 1000 visitors per day). Each year this translates to $220 in hosting fees, plus several hundred dollars in software and hardware upgrades. Anything you send to www.woodcreeper.com goes right back into the site making it better in future iterations.

Thanks for your interest, feedback, and support throughout the years. I look forward to experiencing migration with you again this fall. If you regularly tune-in to any of the other BIRDAR websites, please consider supporting them as well (contact them individually for details), and if you’re interested in joining the growing number of sites yourself drop me a line and I can help you get set up.

Good Birding,

David

Migration contines as front pushes east

National Overview

I’ve said it before and I’ll say it again: migration happens all the time, especially in spring. It’s worth taking a gander at the national composite from yesterday through this morning over at Paul Hurtado’s radar archive here. Looking at that you can really see how migration gets concentrated along the southerly wind field on the east side of the front, but also that birds were pretty much migrating everywhere across the US last night with the lightest movements being in the northwesterly wind field to the west of the front and right along the East Coast. Cool stuff!

Nothing apparent on the radar last night for the Mid Atlantic with strong east to northeasterly flow at all altitudes.

With IA and IL now in the shadow of the last front, northwest winds appear to have kept most birds down last night. There may have been a little reverse migration, or more likely just some localized movements, but no widespread migration could be detected. With all the birds that came in over the last three nights there will be many good birds around the region this morning. Expect birds to begin shuffling into better habitat so go check out that IBA you’ve been meaning to visit for the best chance at high bird concentrations.

Same goes for Wisconsin where all radars indicated a lack of migrants. Most targets were moving N->S at the prevailing wind speed suggesting they were non-avian, but it’s possible that a few birds were in the mix last night… possibly a Summer Tanager catching the next train back south, or some other birds just trying to make a go of it despite the unfavorable conditions. Either way, though, any avian signal was weak at best and so I don’t expect much of  a change from yesterday except that maybe some birds have moved locally to take advantage of better foraging habitat. If you’ve got the time, I’m sure you’ll find some birds today!

Heavy migration into the Upper Midwest

National Overview

The migration superhighway was open for business once again last night as the latest front pushed east across the Plains and Midwest. The heaviest migration was along the frontal boundary which swept across western Iowa and Minnesota by morning. Birders across the Midwest should be seeing new birds today.

The Mid Atlantic was a bit of a mixed-bag in terms of migration last night. Northeast winds appear to have kept most birds down while a few appeared to take the leap anyway. Anything moving was doing so from ESE->WNW, so expect any chance for concentrations to be inland along the Delaware River… but I’m not holding my breath.

Hot and heavy migration up through Iowa and Illinois brought many new birds into and over the region. Birders in Iowa should be out today checking out the local haunts. Around Chicago migration was pushed a bit toward the lakeshore and therefore birders should be heading to the lake to find the best concentrations this morning.

Another heavy migration event into the state last night with the heaviest returns being birds entering from the south and less birds leaving from the north. Birders in the region should be hitting the regular spring hotspots this morning unless you’re near Lake Michigan or western Lake Superior, in which case you should be heading for the lake shore. Migration over Milwaukee and Green Bay was along a distinct SW->NE axis and therefore birds should be in the lake shore migrant traps this morning. Over Duluth/Superior migration was overtaken by heavy storm activity early this morning and birds should have been put down along the lake shore at first light. I wouldn’t be surprised to hear about some great spring birding in that area today.

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.
