In July in central Oregon Western Bluebird parents bring their young to water for a drink and a bath. The entire family arrives together and there is often lots of action with several birds landing on the same perch. This juvenile bluebird landed on dad's perch and later was joined by a sibling after dad left.
I cropped 10% from the left and the top of the photo.
