These birds have a length of 4.5 in (11 cm) and a weight of 9g (0.3 oz). Their wings could range 5-5.6 in (14-15cm)


It is an invertebrate, eating insects and spiders. Due to their cryptic habits, little is known about their diet or foraging habits, but a few observations suggest they forage near grass and sedge roots.


Sedge wrens inhabit sedge meadows and other wet grasslands, such as a pond, marsh, bog, and coastal wetlands. They are found in similar agricultural areas such as hayfields and early successional oldfields.


North American sedge wren populations are migratory. In April and May, northern populations migrate northward. Some of these populations are nomadic, migrating north in the spring, then south in the late summer to breed.
