Adolescent Chicks

The Sparrows' chicks are growing rapidly. 
They seem to be fully feathered on their heads and neck now.
I suspect it won't be too much longer and they'll be climbing out on the perch to be fed.
We noticed the Female appears increasingly tired; she's looking forwards to the baby birdies graduation day, me thinks.
There seemed to be another female doing a song and dance as if courting on the flag pole near the nest and I believe I saw the Male chase another male Sparrow away yesterday.
The bird house may be on multiple listings with the Birdy Realtors Association!
