Regional Overview

In what seems to be a theme recently, migration was broken up over the Northeast by several groups of storms as the high pressure system that brought unseasonably warm temps to many areas got pushed out by the approaching cold front. The storms moved through early, putting a strong damper on the nights migration, but not before many birds had already taken to the air. If storms passed through your area last night, take a couple minutes to check a local migrant trap for warblers, you might find a good flock.

Quick guide to interpreting the radar

On the top row (reflectivity radar), the images show the magnitude of migration. When birds are migrating, it looks like a donut shape around the center of the radar station.

The bottom row is the velocity radar. This shows the direction that the objects detected by the radar station are moving. Blues are moving towards the radar station, yellows and reds are moving away from the station. So for southbound migration, blue should be on the top half of the donut, yellow on the bottom half.

Watch for precipitation moving through during the night hours, this can cause birds to stop migrating in a concentrated area, creating the fabled ‘fallout’, particularly on nights with strong migration.

A night of strong early migration and then storms by Drew Weber. Original content from the folks at Nemesis Bird - fast paced birding.

Regional Overview

It was another night of good migration across the northeastern quarter of the US. Storms slowed down migration in the southeast but birds still were trying to migrate before incoming storms across NY, setting up possible fallout conditions. New Yorkers should be checking inland migrant traps as the weren’t along the lakeshore today.

New York

Most of the action passed through western NY before many migrants were up but from I-81 and east, migrant traps should be checked for higher concentrations of migrants.

More migration plus scattered storms over NY cause fallout by Drew Weber. Original content from the folks at Nemesis Bird - fast paced birding.

Regional Overview

Last night was another night of heavy migration. Northward movement was largely unhindered across the eastern US except in western and upstate NY, where are small line of heavy thunderstorms moved east along the Lake Ontario lakeshore and across the Adirondack’s. With the clear path of strong migration the whole way up the East Coast, there should be a lot of birds moving through. Some of the later migrants should be more evident this morning, with Yellow-bellied and Olive-sided Flycatchers moving through, and Blackpoll Warblers singing everywhere.

I don’t always have time to comment on the radar in each state. To interpret it yourself, read the quick tutorial at the bottom of the page.

New York

The line of storms hit Buffalo around midnight, Syracuse around 1am and the Adirondack’s around 2am. Areas that saw storms last night have a good chance at some fallout, if you can find them. The Lake Ontario lakeshore seems pretty promising as the storms were strong enough to put birds down, and small enough that there should be more birds piling on top of them as they fill in from the south.

Regional Overview

Ohio and western PA saw heavy migration last night but east of there it was much lighter. Light winds from the north and a stationary front sitting over PA were the cause for the less than exciting migration. That being said, there are a lot of migrants around and many were heading north. Migrant traps should be excellent and it is definitely worth checking spruces and flowering trees for Cape May Warblers and other boreal warblers that are migrating though now. The eastern seaboard also saw a heavier migration as the radar over Delaware and New Jersey detected high densities of birds moving north.

Tonight it looks like that stationary front will be still sitting somewhere near the Maryland-Pennsylvania line which may produce another light night of migration on less than perfect conditions.

North winds slow migration in east, tonight could be more of the same by Drew Weber. Original content from the folks at Nemesis Bird - fast paced birding.

Regional Overview

Migration was impressive across most of the US last night. Birds were definitely on the move and there was little to stop them. There was a long thin line of storms moving along the approaching cold front which slowed migration down a bit when it passed, but did not seem to have that much impact on the migrating birds. There should be ALOT of turnover today, so if you have been feeling shortchanged by this migration, its time to get out and do some birding!

Pardon the lack of images. They are coming. I am out scouting for a birdathon this weekend and my remote method isn’t working. Check back soon for the images.

Heavy migration everywhere! by Drew Weber. Original content from the folks at Nemesis Bird - fast paced birding.

Regional Overview

Migration was very evident on the radar last night, with masses of birds flying north with weather that is finally working in their favor. Storms moved into and over western NY and western PA in the early morning hours, possibly setting up some fallout conditions. We are probably at the peak of migration now, and birds have been held up considerably due to the weather patterns over the last 2 weeks. Any fallout could hold excellent numbers and diversity of migrants.

New York

The Ontario lakeshore would be a great place to check, as precipitation moved across the area soon before sunrise. Migrant traps and wood plots along the lake should be very active. Away from the lake, precipitation was too late to affect migrating birds, so migrants should be widespread, with many more breeders occupying territory this morning and an uptick in migrants at most of the regular birding spots.

Heavy migration with western NY and PA fallout possibility by Drew Weber. Original content from the folks at Nemesis Bird - fast paced birding.

Regional Overview

Last night a large front passed through the Mid-Atlantic and Northeast which really slowed migration over most of the region except for the coast and just inland from the coast. Albany, New York City and coastal New Jersey are likely to experience some excellent fallout conditions were the front hit some of the strongest migration yet this spring. Get out there and bird! The diversity should be particularly high right now with the possibility for 30+ species of warbler if you hit the right spots.

I don’t always have time to comment on the radar in each state. To interpret it yourself, read the quick tutorial at the bottom of the page.

New York

The front moved through too early for much of the state to experience any migratory influx. The storms passed through much of the state before midnight but not soon enough to clear out before morning leaving no chance for birds to start again in the morning hours. Albany and Long Island were set up for a good migration when the rain moved in around and after midnight, and there could be widespread fallout in those areas.
