Young Blue Bird tests happiness

My wife took this photo an hour ago
with her Nikon Coolpix P100

From our bedroom, looking through a Nikon ED50 field scope, zoomed in. (See it with "vignetting" cropped out.)
    My wife had been observing the bird house for weeks as the parents checked out the site and finally selected it for their home. The mother laid five eggs, the eggs hatched, and the parents have been busy feeding their babies. Now the youngsters are preparing to fledge.
