The House Wren (Troglodytes aedon) is a small, brown bird found in the Americas. It is a member of the Troglodytidae family, which includes wrens, thrashers, and gnatcatchers. The House Wren is a common and widespread bird, found from Canada to southernmost South America. It is a migratory bird that spends the winter in Central and South America.

The House Wren is a small bird, measuring about 10 cm (4 inches) in length. It has a brown back and wings, with a pale belly and a distinctive white eyebrow stripe. Both sexes look similar, but males are slightly larger and have a louder and more complex song.

House Wrens are insectivores and feed on a variety of insects, spiders, and other arthropods. They are often seen hopping and flitting through vegetation, searching for prey. House Wrens are also known for their habit of collecting and hoarding small objects, such as twigs, feathers, and bits of paper, which they use to line their nests.

House Wrens are cavity nesters and will readily use nest boxes or other artificial cavities. They build large, bulky nests made of twigs and lined with softer materials such as grass and feathers. Females lay 4-8 eggs at a time and both parents incubate the eggs and care for the young.

Despite their small size, House Wrens are known for their loud and persistent singing, especially during breeding season. Their energetic and curious behavior also makes them a favorite among birdwatchers.
