Good Morning: As most of you know, I have had a successful season of pairing a bluebird house on the same pole with a TRES house. Both “couples” successfully raised a group of babies which fledged about two weeks ago. My bluebird couple quickly built a new nest and have 5 eggs to tend to. The TRES house is empty. I had read that it is unusual for TRES to have more than one brood, so I wasn’t really expecting them to nest again. I have left the house undisturbed (other than cleaning out the nest) because I occasionally see the TRES flying around the house and even looking inside. I was wondering, do you think I should plug up the entrance to that house. . .or even remove it from the pole all together? I am afraid that it may draw “undesirables” near my bluebirds.
Sometimes the do have more than one brood but unless they are banded it’s impossible to know if it’s the same pair or a new pair taking over the box. But it’s late in the season for TRES anyway. I agree with Carol.
