Mountain Bluebird baby

This little Mountain Bluebird, maybe 10 or 11 days old if I remember correctly, was about to have a tiny band put on it's leg - actually, on its foot, to be correct, as the joint on a bird's leg is the ankle, not the knee : ) Seen on June 11th, when I went with a friend on his Mountain Bluebird route SW of the city with several other people.
