7 or 8 counted flying overhead. First section of the recording had 1 bird closer and the others still distant; then that original closer bird flew back to the others and 2 minutes later they all flew right over my head, circled, and flew back over to the area where they had originally been (group of white pines). I normalized the recordings to -3.0 dB according to the eBird guide to audio preparing & uploading
