The Carolina Wren, like the House Wren, like a bird house that sways. The entrance is larger than that of the House Wren. The extra width gives Carolina Wrens the ability to carry wide sticks into their house for nesting material. Hangs with a metal chain and opens easily for clean-out.
Most birds prefer a stable house, but House Wrens don't mind a gentle movement. Hangs easily with the metal chain from a tree or bracket and opens easily for clean-out.
With its 1" entrance hole, this house provides great protection for House Wrens. Wrens are very protective, so position the nest box in less frequented areas.
