Birders

I've never attempted to stop wrens and quit having Bluebird nest boxes because of them.

Link to wren issues. Good Luck

Methods of discouraging House Wren nesting (most effective methods are in bold) include removing dummy nests, avoiding marginal habitat, use of a classic wren guard, half circle wren guard, raised roof nestbox, modified Noel guard, avoiding crowded boxes, painting the exterior of a box white (not red/green), opening/plugging the nestbox, raising the height, avoiding slot boxes, avoiding gourds on trees, keeping them busy. Bob Benson was thinking of hanging a sign on his boxes that say "Not for Wrent."Also see other methods, what doesn't work, and other points of interest. Also see unusual House Wren nest made almost entirely of grass.
