Carolina wrens (Thryothorus ludovicianus) are small, brown birds commonly found in the eastern United States. They are known for their loud, melodious songs and their elaborate nests, which they build in cavities or sheltered locations.
Carolina wrens typically build their nests in the spring, using a variety of materials such as twigs, leaves, moss, and feathers. The nests are usually cup-shaped and have a small entrance hole. The female wren lays 4-6 eggs in the nest, which she incubates for about 12 days. The chicks hatch altricial, meaning they are born helpless and rely on their parents for food and care. The chicks fledge from the nest about 16 days after hatching.
