OCCUPIED

The male Wren arrives in early spring and establishes a territory of about 1/2-3/4 acres.  He keeps watch over this area from three advantage points, while singing from dusk to dawn.  His singing is loud and diverse (and I find lovely!).
I watched as the male Wren busily filled several birdhouses in our backyard with twigs.  Once finished, he presented the different nest to his mate.  She selected this particular birdhouse and began adding additional twigs, along with grass and pine needles.  Breeding season begins in March and runs through July.  This is the second nesting.  (The first brood was raised in the birdhouse outside our front door.)
Come Autumn, Wrens head south for the winter.
