A wren is a small, brown bird belonging to the family Troglodytidae. These birds are known for their energetic behavior and distinctive, cheerful songs. Wrens are typically found in a variety of habitats, including gardens, forests, and wetlands, and they often build their nests in dense vegetation or cavities. There are over 80 species of wrens, with the Carolina wren and House wren being among the most common in North America. Wrens are insectivorous, primarily feeding on insects and other small invertebrates. Their small size and quick movements make them agile foragers in their natural environments.
