• 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.
• A pair bond may form between a male and a female Carolina Wren at any time of the year, and the pair will stay together for life. Members of a pair stay together on their territory year-round and forage and move around the territory together.
• Breeding from Canada southward to the southern tip of South America, the House Wren has one of the largest ranges of any bird found in the New World.
• A male House Wren may lay claim to a nesting cavity by filling it with more than 400 small twigs. If the female likes what she sees, she will then take over, adding the nest cup and lining it with grass, inner bark, hair, and feathers.
• The stick-filled cavity of the House Wren nest provides “stilts” for the nest cup which allows rainwater to collect in the bottom of the nesting cavity without endangering the eggs or young.
