Regional Overview No time this morning to post much of an analysis, but migration was pretty strong and several people were reporting good calling rates as birds flew overhead. Foggy conditions in some places were amplifying this effect as birds flew low. The lower flying birds are not as detectable on radar so the volume of migrants across NY may … Read More
Great migrations on light winds
Regional Overview Last night was another good push of migrants. There were good conditions to let birds fly unimpeded through NY and northern OH but points south experienced storms overnight that may have produced localized fallouts. There are already reports coming in of very high volumes of flight calls being detected this morning in NY and PA. Check the radar … Read More
Strong migration with possible PA fallout
Regional Overview I am writing this as I listen to thrushes stream overhead, primarily Swainson’s Thrushes but there are some Gray-cheeked Thrushes mixed in as well. Last night the radar boomed with migrants as they took advantage of a return of north winds across the region. Birds were streaming over the Great Lakes (check the Buffalo radar to see them … Read More
Migration to the south, storms from the west
Regional Overview Scattered rain and storms moved across the region from the west, blocking any type of broad movement of migrants last night. With limited migration the last two nights, the best spots to look for warblers and other migrants are areas with abundant food resources. No new birds were arriving in the region, but by the same token, birds … Read More
Slow night of migration across the region
Regional Overview The volume of migrants in the air was greatly reduced last night compared to the last several nights. The primary cause of this was the moderate south wind that dominated the region last night. The velocity radar bears out the the idea of little migration last night as the radar did not detect objects (birds) heading in a … Read More
Strong migration again
Regional Overview There was widespread migration across the region last night with very little weather to slow birds down. Scattered showers across Pennsylvania and along the Great Lakes may create higher concentrations of migrants. Check out the animation for your region below to see if any rain clouds moved through overnight. This often means there will be a lot of … Read More
Heavy migration with scattered storms
Regional Overview Migration was strong across most parts of the region last night as the winds turned and came out of the west and northwest. There were some scattered showers moving across Ohio and northwestern Ohio that may have resulted in migrant concentrations and a larger storm that moved through parts of New York. Elsewhere the migration was pretty strong. … Read More
Storms shut migration down
Regional Overview Storms and southwest winds combined to create conditions not conducive to migration. All the reflectivity radar images showed little to no detectable movement, while the velocity radar showed everything that was detected moving north, so there were likely very few birds in there. Tonight could see the winds switching around and coming from the north which may spur … Read More
Migration sticks to the coast
Regional Overview South winds kept birds from migrating at levels that would be detected on radar. However Mike Lanzone down in Somerset County PA said he was detecting a moderate low level movement last evening with about 15-20 flights calls being detected per minute. If this low-level movement was widespread across the region there could be concentrations of migrants in … Read More
