Heavy migration and some interesting storms in the east

Regional Overview

Migration was heavy across the region, but particularly so in western PA, New York and Ohio (notice all the green in the center of the blue ‘donuts’ on the radar. Winds were light and birds definitely took advantage of that fact and took to the skies last night. There should be a lot of new arrivals and densities of new birds should be higher than previous days. The only precipitation in the region was a storm that worked its way through NY early in the evening down to eastern PA after midnight last night.

There was heavy migration in the western part of the state, but it was going pretty strong in the east as well. A storm that worked its way through se PA may have been well timed to create fallouts of warblers and other migrants. For eastern PA birders, check migrant traps along rivers and in urban parks for possible fallout concentrations of migrants. Migration was not as heavy in the east, but there were still a lot of migrants filtering into the region from the south.  In central and western PA, there were a lot of birds moving through so check those tried and true parks and good habitat to find warblers foraging after a good night of migration.

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

Maryland radar showed moderate to strong migration last night, with birds moving from SW to NE. This movement could be good for concentrating birds along the western side of the bay this morning, so check migrant traps along there.

New York

New York saw some heavy migration right before the storm moved through early in the night. NY birders should be expecting a really great influx of warblers and other Neotropical migrants as birds move through PA and reach breeding spots in NY. The storm may have been early in the night but may still have created some fallout conditions as it appears not as many birds were migrating after the storm. Check traditional migrant traps.

In northern Ohio the migration appeared quite strong on the radar, with the velocity radar showing the main movement heading in a SW to NW direction along the lake. Migrant traps along the lake could/should be fantastic this morning!

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!
