About House Wrens

House wrens are probably the easiest cavity nesting birds to attract to birdhouses. They can nest in birdhouses with a hole size that ranges from 1 to 1 ¼ inches. This size excludes House Sparrows, an aggressive alien species that competes with our native cavity nesting species. Unfortunately a hole size under 1 ½ inches also excludes bluebirds and titmice, two desirable native species that readily nest in birdhouses.

The best birdhouse hole size for smaller birds, like the house wren, is 1 ½ inches. This size allows more species to use the house but excludes the larger European Starling, another aggressive alien species that competes with our native cavity nesting birds.

House Wrens Battling for a House

These house wrens had just arrived in the spring of 2012. They obviously both want the same house. Watch as they battle for it.
