Globally, over eighty species of wrens exist. 11 of these species reside in North America. Some species are more common than others. This is a complete guide to every species of wren in North America, including identification pictures, their range and which habitats you can spot them in.
What is a Wren?
Wrens are small brown birds in the Troglodytidae family. This is a family of birds that is diverse and span across the globe. They are small, often brown, with compact, rounded bodies. Their tails are short and upright and may appear cocked. They have slender, pointed bills and have dark markings on their backs and wings. Some even have a unique pale marking resembling eyebrows.
Wrens are active and curious birds. They are known for ‘disappearing’ into tight spaces in search of their primary food source: insects. They are territorial and quite feisty during the breeding season. While wrens are social, they prefer to nest alone. These birds are also very vocal – a characteristic that makes them easier to spot.

Why Conservation of Wrens Matters
Wrens control insect populations and are also an important food source for predators, providing a balance in the food chain. They are also culturally significant, often featured in folklore, songs, and art. While most of these birds are not currently at risk, some species, including the California and Carolina Wrens, face threats due to habitat loss, invasive species, and climate change.
