Nice, yes we have 2 boxes and have seen 2 pairs this year .One built a nest and then abandoned it, some wrens tried to move in and we foiled that, now the bluebirds are back looking more serious. Wrens are terrible to bluebirds. I’m guessing you are more south than we are in Michigan. Congrats on your bluebird chicks I ordered some dried mealworms on ebay for when ours have chicks to feed. We do have lots of bugs around but why not spoil them! We also have nesting tree swallows in 2 nests on either side of our barn. They eat lots of mosquitos.
Yes, I live in central Indiana. My bluebird antagonists are House Sparrows, so I’ve put out 4 houses for them to choose from. Usually the bluebirds pick a certain one, but this year the Sparrows started building there. I keep taking out their nest, but they build new ones back. You’d think they’d take the hint. Anyway, Billy and Betty Bluebird (I name most all of the birds I have regularly) chose a different house next that one this year. I have successfully had bluebird babies the last 3 years, and hope they keep choosing one of the 4 houses I offer. My home is in a semi-rural area, just on the outskirts of a small town. I feed the bluebirds mealworms year round, and they visit daily except during when they are teaching the kids where the regular insects are. Then they come back to the feeders after about 6 weeks off. They stay throughout the winter so I’m lucky.
