First bee in bee hotel.

Seems to have started 6 adjacent nests, with an end plug in each. Spent the night in the middle of one of the holes with her head facing the plug.

Exited a 7 mm diameter drilled hole in spruce stump.

He poked his head out for a few minutes, then went back in for a few more. Then he came out, walked around a bit, and flew away.
