Recorded SE Pennsylvania around dawn on Monday. 1 bird in flight My guess is that the bird was smaller than a American Robin. There was either a single call or two paired together as shown in the attached jpeg. Duration < 20 ms, which is much much shorter than sparrows. I ran through everything else that I could think of that would reasonably be flying around (I was hoping for American Pipit, but that didn't match.) Frequency was in between 3-4 kHz.
