Tree Swallow

This morning I watched a pair of swallows as they guarded their nest box.  At least that's what I assume they were doing.  First the male sat on top of the house, then when I returned, the male was going inside, and the female went to the roof.  I was hoping the male would come back outside so I could capture them both together, but no luck.

Thank you for the lovely comments about my little chipmunk yesterday!
