Cobb’s wren is found only in the Falkland Islands.
On 28 July 1908 on Carcass Island Arthur Cobb shot a wren using rice as the charge. The specimen was skinned and sent to the Natural History Museum in London, where it was studied and described as a new species, Cobb’s Wren Troglodytes cobbi. Though considered later by some ornithologists to be a form of the continental House Wren, it was confirmed (1993) as one of the two endemic Falkland bird species, with the Falkland Flightless Steamer Duck.
This bird is restricted to outer islands that have remained free of introduced predators (cats, rats and mice). It has Vulnerable conservation status (BirdLife International) primarily because of the destruction of its tussac grass habitat, introduction of predators and the small geographic range of its scattered population (estimated at about 6,000 pairs on 29 islands in 2001).
The ideal habitat for this bird appears to be dense tussac grass growing from high water mark behind a boulder beach with accumulated dead kelp (seaweed) in which invertebrates thrive.
A Species Action Plan (384kb PDF) has been produced by Falklands Conservation and the Falkland Islands Government to protect this endemic bird.
