Weather: Thin fog; fog during night. By 6:05 AM bird below road gave two displays. Then displays above the road. @ 6:10-6:11 another display below road. (None saved as poorly recorded). After this, some recording of ascending whistles (one) and two displays were saved. Subsequent displays not recorded, but observations again showed that bird displayed back and forth, apparently with a female as the "focus" of its movements. The last display I noted to be @ ~ 6:20 AM.
