Migration continues tonight!
Here are the radar and velocity from just after sunset until 9:45pm this evening
This movement appears to be less than last night (less continuity, less of the green signal which represent higher densities of birds). A lighter movement is pretty typical for the second day of a multi-day migration event. I suppose this is due in part to the number of birds that had been waiting around to depart last night, and that new arrivals are more likely to stick around for a few days and fatten up in anticipation of the next migration opportunity (especially early in the season).
Either way, I would expect today’s birding conditions to persist into tomorrow morning, with both an exodus and influx of individuals overnight. Thursday night is predicted to bring some precipitation along with southerly winds, but because birds will have been moving over the two preceding nights, I think the chances of seeing any significant concentration of birds due to weather are slim.
Remember to come back and post your observations!
Good Birding
Morning Update
Here’s the radar from midnight last night through 5:45am this morning.

How do you make the radar loop at the Mt. Holly NWS weather site cover a longer period of time? It seems to cover only the preceding 90 or 120 minutes or so?
I thought I would call up the rest of the night’s flight from that website, but can’t get a longer timeframe.
I would do it from the real-time radar site (http://www.rap.ucar.edu/weather/radar/). Choose the time you want the loop to end and the number of hours you want it to cover back from the end time. For example, in the morning I would choose 10:00am (UTC is 4 hours later than EST so this would correspond to 6:00am EST), and go back 6 hours which would take you back to midnight. That will give you a good snapshot of the overnight migration until sunrise. I would do it for DIX (Mt. Holly) and DOX (Dover AFB) as well as regional composites to see how the entire NE is doing. This is basically what I do when I report the radar.
Hope this helps 🙂
David, great site. I’m sending all my non-birding friends there and they love it. I’ve blogged about your site at my birdchaser.blogspot.com. Very cool.
Thanks Rob! 🙂
