Feeding junior

This wren house is under the eaves next to our living room.
We get to watch the steady routine of the adults coming in with various insects for the brood.

Troglodytes aedon .

For House Wren eggs, temperature inside the nest box can be critical to survival. If a sun-drenched nest box warms above about 106 degrees Fahrenheit for an hour, the eggs will begin to die. If a cold snap chills a nest below about 65 degrees Fahrenheit for more than a day it can also doom the eggs.
