High Quality Content by WIKIPEDIA articles! Cobb's Wren (Troglodytes cobbi) is a fairly small (12-13.5 cm) wren which is endemic to the Falkland Islands. It was formerly classified as a subspecies of the House Wren (Troglodytes aedon) but is now commonly considered to be a separate species due to differences in plumage, voice, ecology and morphology. The plumage is brown, greyer on the head and breast and more rufous on the tail. There are dark bars on the flight feathers and tail. The bill is long, blackish and slightly curved. The main confusion species is the Grass Wren which is smaller with a shorter bill, buff eyestripe and dark streaks on the back and head. Cobb's Wrens have a number of buzzing calls and their song is a series of jumbled trills and whistles. The song can be heard from August to February and varies between individuals with different males having different song patterns.
