Wrens: Troglodytidae

The eating habits of the majority of wrens remain unknown. The wrens whose eating habits are known—particularly the ten North American species that have been well studied—are primarily carnivores, eating insects. Cactus wrens are one of the known exceptions, eating large quantities of vegetable matter, such as cactus seeds. Other exceptions are the Carolina wren and Bewick's wren, which feed on berries and plant seeds in the winter.

Some species' diets might also include small frogs or lizards. Wrens usually look for food from their perch rather than catching it in midair. Some species gather their food from whatever is scattered over the forest floor. Most of the other species (whose habits have been observed) feed in the bottom areas of tangled vegetation, with some hunting at slightly higher levels. Some tropical species will follow ant swarms, but none do it on a regular basis.
