There are 88 species of wren that are divided into 19 types (genera). Let’s dive into the diets of some different wren species.

What Do House Wrens Eat?

House wrens eat small insects, worms, spiders, and larvae. They mainly forage on the ground but will also hover to pick prey from leaves and bark. House wrens will also eat flying insects that they can catch in mid-air.

If you’re building a bird-feeder or want to attract house wrens consider mealworms, bark butter, or sunflower chips.

Winter Wren

Winter wrens are more commonly found in evergreen forests. As with most wrens their diet is heavy in insects ranging from flies, to ants, to millipedes, and spiders. However, they will also consume more northerly vegetation such as juniper berries as well.

Eurasian Wren

One of the most widespread wrens, found in Europe, North Africa and temperate Asia. The Eurasian Wren eats insects, spiders and other small invertebrates, including earthworms. It also eats berries, fruits and nectar.

Carolina wrens eat suet, peanuts, and insects ranging from caterpillars to beetles.

The majority of a Carolina wren’s diet comes from insects rather than nuts or other non-carnivorous sources. However, with their calls that can be heard across long distances, many bird enthusiasts wish to attract Carolina wrens to their feeders.

If attracting Carolina wrens to feeders, keep in mind that during the winter (especially in their northerly range), supply of insects will be limited. For this reason, wrens will be attracted to feeders that supply both suet and peanuts. Mealworms are also a favorite of Carolina wrens.

The Top Feeder Foods for Wrens

It’s important to remember that most wren species primarily eat insects. As such, if you wish to attract wrens to a feeding station the top options are foods like mealworms, crickets, and grasshoppers. However, especially when wrens are struggling to find insects in more northerly environments, they may be drawn to more options such as peanuts and sunflower seeds.
