Another night of northerly winds had the birds up and moving last night. Winds started from the NNW after sunset, and have switched around to the N inland, and the NE on the coast. Here’s the radar from sunset last night through sunrise this morning. With the warm days and dropping temperatures at night, we would expect some anomalous propagation from the temperature inversion, but you can see from the velocity image that most of the activity is indeed birds (ie. moving from N–>S at a velocity 10-15kts faster than the prevailing winds; which were about 5kts).
Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.
Fall migrant traps are the best bet for today…okay, I’m out the door!
Good Birding
