Caught my 1st HOSP this morning and cleaned out TWO other completely filled HOSP nests. I knew there was a pair staking claim to the nest where I set the trap, but couldn’t believe they built two other nests without my knowing. My pair of BBirds had been trying to claim this box, and it wasn’t 15 minutes until they were on this house again, going in and out out of the hole. I will be keeping a vigilant watch from now own. Spring is around the corner. (P.S, I caught the HOSP within 15 minutes of setting the trap and there are plenty more out there). Sure hope my blues get at least one box to nest in (I have 4), although it is plenty early.
