By July most bluebirds are done nesting. Those who are working on a mid-summer family keep the number small.
There were three eggs in this nestbox. Two hatchlings are getting ready to fledge, a male in the front and a female in the rear.
This nestbox is closer to the house than the boxes the bluebirds usually select. I've enjoyed watching frequent streaks of blue as the parents fly into the yard to gather food. No shortage of insects here this time of year, especially mosquitoes.
