The baby bluebirds have grown up and flown away. Here is a photo that my husband took a couple of days before they left the nest.
They will spend the next couple of weeks hiding out in the woods close by while they learn how to fly better. The parent bluebirds will still help feed them while they learn how to feed themselves. There was one egg left in the nest that didn't hatch. We are hoping the parents will come back and raise a third batch of beautiful bluebirds this year. Bluebirds are territorial and this particular couple have claimed the bluebird house in our backyard. It helps that my husband keeps a feeder stocked with mealworms!
