A House Wren will love this house. House Wrens are one of the few  birds that do not mind a house that moves.
Our hanging wren house is a little larger than most, the size is more in line with what is recommended.
Our house has a 1 1/8'' entrance hole, a side door for end of season clean out, a rough interior and it is vented under the roof.
It has a cord for hanging.
