ハシナガヌマミソサザイ Cistothorus palustris

Small, spunky wren with boldly patterned plumage. Look for dark cap, bright white eyebrow, and black-and-white stripes on back. Compared with similar Sedge Wren, Marsh is overall darker and more contrasty; especially note the solid brown shoulder patch and unstreaked crown. Habitat is also a good clue for identifying this wren: rarely strays far from water, especially extensive cattail marshes and rushes. Migrants are occasionally seen in wet weedy fields. Often difficult to see well as it skulks through reeds, but often perches conspicuously when singing. Variable song usually a gurgling trill with some introductory notes.
