Endemic to the Falkland Islands, where it is found in seashore areas and offshore islets, typically in association with tussac grass. Often forages on rocky beaches, picking at food items washed up by the tide. Somewhat similar House Wren has wandered to the Falklands before, but note present species’ gray-brown head and neck, lack of a prominent eyering, and longer darker bill. Can be tame and confiding, allowing close approach. Rattling song, somewhat similar to that of House Wren, can be given from an exposed perch or deep in cover. Calls include nasal mews and harsh, dry churrs and rattles.
