Saw this last night in Bucks County PA. People say birds, it could be… but they sure are glowing.

Time:10:40

Location: Twin Oaks, Levittown PA

Saw this while driving home at 9:45 at night. Recorded a bad version on my phone but got home and got out my Sony FX3 with a 70-200 2.8 lens. Waiting around for about an hour and was about to go in before is showed up again. 

Does look like birds. But in 42 years of life I have never seen glowing birds in the sky. Did see someone else post a similar video from Queens NY last night so that seems weird.
