Here are the radar and velocity from sunset last night through 5:15am this morning. This one is tricky though, because although there appears to be a lot going on, most of the signal is not bird migration. Use the velocity plot as a “filter” to determine how much of the radar is actually bird migration. […]

Birds are on the move- but they’re moving along the central and southern eastern flyways. From the Great Lakes to Mississippi and over to Florida, birds are high-tailing it south, but along the northeast coast they’re waiting until optimal conditions return to the area. The radar loop shows only a few images representing 4 hours […]

Southeast winds are keeping things slow. Last night was another one filled with anomalous propagation, but no detectable migration. Tonight is likely going to be the same, and I don’t expect things to pick up again until the winds switch Wednesday night. I’ll keep you posted as things change, until then, go out and find […]

Here’s the radar from sunset last night until sunrise this morning. Now, although the reflectivity looks impressive, if you check the velocity you’ll notice something fishy. It appears that there are two directions that things are moving through the radar beam (direction is from – to +, or in this case, from green/blue – yellow/red). […]

Here’s the radar from sunset Sept. 10 – sunrise Sept. 11, which shows a pretty heavy migration across our area especially down the coast and bay shore.
