There are several nest boxes for Purple Martins on poles at Point Hudson
in Port Townsend, each now with a couple claiming occupancy. Today they
were sitting on the porch shelf by their entrances. There are no RV
campers now due to COVID19 lockdown, so I positioned my pickup and used
400mm lens through the window with good results; see at BIRDSBYDAVE.COM.
