More heavy migration across the Eastern Flyway!

Surface winds were light and northwesterly last night, with a slight southwesterly component at 3000 feet. Apparently birds ignored the high-altitude winds, as heavy migration was apparent up and down the eastern flyway, from Maine to Florida. Here’s the radar from 6:00pm last night through 6:00am this morning. Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

Based on the radar, most birds appeared to be taking a NW->SE trajectory, which is consistent with the light northwesterly winds present this morning. Expect coastal locations to be birdy this morning, especially migrant hotspots such as Cape May and Sandy Hook (the Sandy Hook buoy indicated NW winds at 6kts, which is exactly what you want to keep birds on The Hook in the AM).

Good Birding

    I had 6 REDSTARTS, 1 BLACK and WHITE WARBLER, and 1 BLACK-THROATED GREEN WARBLER at the National Park dredge spoils in Gloucester County along the Delaware River. This is actually pretty light for here, so the birds must have continued on as you said!
