Bluebird chicks

We were away for a week, and then didn't check the birdhouses last week. But today, we took a look at the bluebird house and found four chicks, all fairly large with well developed feathers. This is the same nest as covered in the April 30 ("Time for Eggs") and May 4 ("Revisited") posts, where five eggs were incubating. Unlike the calm female we found in that previous post, today she was quite agitated, complaining loudly from the nearby trees as we opened the box. These four will likely fledge in the the next few days, and likely receive yet another post, especially if we can see the little guys afterwards.
