Slow night on the Eastern and Atlantic flyways

Regional Overview

North winds and precipitation last night really limited the amount of movement across the entire eastern part of the US. You can see in the composite reflectivity above that there is very little migration evident on the radar east of the Mississippi. This could be good if you had a variety of migrants around yesterday as they should still be around, foraging in insect rich areas or back on breeding grounds establishing territories and breeding.

Little migration across Pennsylvania last night with the less than ideal conditions. Best chance to see warblers is to hit up good habitat and breeding grounds. Remember to enter any breeding evidence you see into eBird!

As always, please leave me comments on what you find out in the field.

With the north winds last night, expect the good variety at Crane Creek to continue. Little to no migration was evident on the radar with all movement on the velocity radar in a southward direction. Most birds that were there yesterday will likely stick around for toady but there will be few new arrivals. A Kirtland’s Warbler (or two or three) was seen yesterday so it/they may have stuck around the boardwalk/beach area for today.

I need your help! These reports will only be as good as the feedback I get on these updates. Please leave comments on interesting patterns of migration you are seeing in the field so I can incorporate some ground truthing to my forecasts and predictions. Thanks!
