We have a pair that visit out peanut feeder daily. There is a large maple tree in out back yard that has many dead limbs with multiple holes very high up. I have been unable to determine if any of them have occupants.
Thank you very much, Ballard. Busy for sure, but we've had some weather hi 20's - mid 30's and they seem to take some time off. Probably need all the energy to keep warm.
