Wrens

Wrens are a family of small brown passerine birds mostly found in the New World, with 88 species spread across 19 genera, while the Eurasian wren is the sole representative in the Old World. Known for their loud and intricate songs, wrens usually have drab plumage with barred patterns on their wings or tails, and they often perch with tails held upright. These birds are mainly insectivorous, dining on bugs, spiders, and other small invertebrates, but they'll also eat seeds, berries, and occasionally small amphibians like frogs or tadpoles. They have short wings and, depending on the species, can be quite bold or very secretive in behavior. Most wrens are non-migratory, but some that live in temperate regions do migrate. Their nests are usually dome-shaped, and while the Eurasian wren has often been associated with humans, others prefer a more solitary existence in a wide range of habitats including forests, deserts, and grasslands. The term "wren" has historically been used in folklore and has been applied to birds that are not related taxonomically, causing some confusion. Wrens are celebrated in human culture, with species like the Eurasian and Carolina wrens featuring in mythology, traditions, and even being used as state birds or on currency.
