With the winds dying down a bit, and the pool of migrant-ready birds reduced, last night’s migration event was clearly smaller than the last few nights; but the differences are only apparent relative to the heavy migration recently experienced. Here’s the radar from 7:00pm last night through 5:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

Winds were light and northeasterly last night, and migration over the region followed a NNE–>SSW trajectory. As the night was clear and winds light, expect birds to be dispersed across the landscape this morning, favoring slightly more inland locations than coastal ones due to the easterly winds. As I said yesterday, the result of several nights of migration should mean that most locations will see a net increase in bird density (as recent arrivals require a few days of refueling), so today and tomorrow will be good days to get out and do a little birdwatching.

I have received a few emails lately with questions about interpreting the radar. Therefore I have begun to update the Radar and Migration FAQ, which you can access from the button in the upper-right corner of this page.

Good Birding
