Nothing like a cool bath on a hot day?

I have become accustomed to the Starlings taking a dip!
  But only on the occasional instance have witnessed the Robins taking a dip?
  This appears to be only a youngster so is not quite as cautious as the adults?
  It was have the time of its life.It enjoyed the first dip so much.That after flying up into the tree to groom.It returned for a second one.
