20-50 bees were cruising around a small (1m2) area of open soil. Females were often landing and investigating crevices. Couldn't tell if they were emerging or aiming to dig. Many males as well (see second image), and often tackled females, though it didn't seem that they were ever successful in mating (no photos revealed even correct orientation, let alone visible genitalia). Keyed using pinned specimens, and got confirmation from bugguide-ascher

The two Pileated Woodpeckers were digging into several trees at the back of our property. From inside our house, I could not tell the sex of each bird. They were spectacular! I went outside later and saw the oval-shaped holes that they created.
