It’s a cool damp day and the bluebirds haven’t shown any more signs of nest building. After breakfast today Mama went into the house and stayed for quite some time. Daddy perched on the roof, constantly peering over the edge.
I think bluebirds have an innate sense of chronology that tells them when there are enough insects available to feed a brood and that is going to be awhile.
It’s not too late to put up a nest box and get bluebirds this year. It’s one of the best things you can do for bluebirds and yourself. The box needs to be 4-6 feet above ground and design approved by North American Bluebird Society. Important tip: take a bar of soap and rub the roof good or you will attract wasps before you do bluebirds. Also keep in mind that if you host bluebirds you need to control house sparrows. If you can’t do that, then don’t put up a box. House sparrows are bluebird killers. That includes eggs, chicks and adults. HOSP control is not a pleasant aspect of hosting bluebirds, but a necessary one. The rewards are worth the effort.
