House Wrens rear brood in old nest of Robins.

parent that I now hear it distinctly while in every 
room in the second story of the house, through the
open window 15 or more feet from the nest. The 
hungry chirping of the young robins mingling with it 
is further and louder yet not on the whole so very
different. Last year a House Wren breeding at our 
Concord farm made a similar addition to the 
nest of a Phoebee [Phoebe] in the wood shed there but
it was not begun until after the pair of Wrens
had hatched their second brood in a bird house 
on a nearby pole and no practical use was afterwards 
made of it by them. The sticks seemed to be brought in 
only by the [male] Wren, constantly in song while thus 
employed. They were regularly thrown out towards 
the end of every day by the Phoebees although these 
also had ceased to use it at the time.
