House Wrens are just one of the many songbirds you will see in your backyard soon. The male House Wren is getting very busy choosing good nesting sites for the female House Wren. Males will sing while building partial nests which ensures territorial claim.
The male House Wren will build these partial nests in several birdhouses. Once the female House Wren selects a birdhouse she mates with the male that built it for her.
You will know by the beautiful song they will be singing together.
