Sedge wren Cistothorus stellaris

Tiny, bubbly, buffy-colored wren of damp grassy areas. Brighter cinnamon wash on flanks. Compared to similar Marsh Wren, note head pattern: Sedge has streaky crown and much less obvious pale eyebrow. Sedge also has barred wings and lacks plain dark brown shoulder patch. Also note habitat differences: prefers damp weedy fields and meadows, not cattail marshes. Generally secretive, but perches up when singing. Like most wrens, small size contrasts with large voice: one or two introductory notes followed by a loud, sharp, metallic trill of varying speed. Breeds mainly in the central U.S. and Canada; winters to northeast Mexico.
