Introduction to Wrens

Wrens are a type of brown bird with upright tails that are often found darting in and out of shrubs and bushes. They are known for their insect-based diet and cheerful songs that are often heard during the summer months.

In this article, we will be exploring the different types of wrens, their characteristics, and their role in the state of Iowa.

Characteristics and Diet of Wrens

Wrens belong to the Troglodyidae family, a group of small and often inconspicuous New World birds. The Eurasian Wren is the only species of wren found in the Old World.

Wrens are known for their small size, with most species measuring between 4 to 5 inches in length. They have short wings and tails, allowing them to quickly dart and maneuver through vegetation.

Wrens are insectivores, which means they feed on insects. Some common insects eaten by wrens include beetles, ants, caterpillars, and spiders.

They are known to forage on the ground and in shrubs and bushes, searching for prey.

Classification of Wrens

As mentioned, wrens belong to the Troglodyidae family, which is divided into two subfamilies: Troglodytinae and Polioptilinae. The Troglodytinae subfamily includes species such as the

House Wren, Winter Wren, and

Carolina Wren.

The Polioptilinae subfamily includes species such as the Blue-gray Gnatcatcher and the Ruby-crowned Kinglet.

Folklore and Superstitions Associated with Wrens

In some cultures, wrens were considered bad luck, and killing a wren was thought to bring even worse luck. In some European countries, people would go on a wren hunt on St. Stephen’s Day, where they would kill a wren and parade its body through town.

This tradition likely dates back to pre-Christian times, where the wren was considered a symbol of the old year, and killing it was seen as a way to usher in the new year.
