It not is recommended that the box be placed in trees or on buildings. It is recommended that the box also face bushes, shrubbery, trees, or such to provide a place for fledglings to flee to. Boxes should be well spaced as Bluebirds become aggressive and territorial during mating season. A mature female will generally raise two sets of offspring each season. The female usually incubates eggs for 13-16, and then hatch.
Fledglings are usually a grayish color with speckles on the breast and blue on their wings.
Both parents care for the fledglings for an approximate 15-20 days, feeding them a diet of insects. After said time, the fledglings leave the nest to produce families of their own, but usually do not venture too far away. Some studies have observed the young staying near the mother s nest in order to help with future nesting duties. Don't forget to subscribe to our Newsletter. All rights reserved.
