Cistothorus stellaris
The Sedge Wren, *Cistothorus stellaris*, is a diminutive and elusive songbird, measuring about 10-11.5 cm in length with a wingspan of 12-14 cm and weighing a mere 8-10 grams. Its plumage is a striking pattern of warm browns, featuring a heavily streaked back (which gives rise to its scientific epithet "stellaris," meaning "starry") and crown, contrasting with paler underparts and unbarred flanks. Key identification marks include its short, often cocked tail, a distinctive white supercilium, ...
Primarily found in wet, grassy habitats including sedge meadows, fens, marsh edges, and damp prairies with tall, dense vegetation. It typically inhabits low-elevation environments.
The Sedge Wren's diet consists almost exclusively of small insects and other invertebrates, such as spiders, grasshoppers, beetles, moths, and caterpillars. It primarily forages by gleaning prey from dense vegetation close to the ground.
Sedge Wrens are primarily diurnal but notoriously secretive, spending most of their time concealed within dense grass and sedge clumps, making them difficult to observe. They forage by gleaning small invertebrates from the stems and leaves of low-lying vegetation, often creeping mouse-like throug...
The Sedge Wren exhibits a somewhat disjunct breeding range across central and eastern North America, extending from the Canadian Prairies eastward through the Great Lakes region and into scattered pockets of the eastern United States, including parts of New England and the mid-Atlantic.
