House Wrens

House Wrens nested in the bluebird nest box.

Looks like they lined the nest with pine needles, spider webs and dryer lint.

House wrens nested in one of my bluebird houses this year.  I know they had two, if not three, clutches of eggs.  There was a lot of care and feeding involved in raising all those young.  The male wren fills the box with short sticks.  He might fill other bird houses and nesting cavities in the vicinity just to reduce competition.  Then the female comes alone, surveys his work, tosses out any unnecessary sticks, and lines the nest with softer items.  The female will lay between two and eight eggs.  House wrens are not as spectacular looking as bluebirds but I do appreciate their pugnacious attitude.
