Fun Facts About Wrens
- You can increase your chances of attracting Carolina Wrens to you feeders by providing a brush pile close to your feeding area. They feel more secure with a place to seek refuge nearby.
- A single male Carolina Wren can sing up to forty different songs – up to 3,000 times in a single day
- A female Carolina Wren is unable to defend her territory alone if her mate dies, so she spends much of her time watching for predators as they forage together.
