Troglodytes cobbi (Cobb’s wren)

Troglodytes cobbi (Cobb’s wren) is a wren found only in the Falkland islands. Troglodytes cobbi is named Cobb’s wren after Arthur F. Cobb who collected the first specimen from which the species was described on Carcass Island, Falkland Islands, in July 1908.

Classified as ‘Vulnerable’ to extinction by the IUCN due to

  • the very small overall range (270km²) of the wrens habitat
  • living on islands with a high susceptibility to invasion by rats
Threats

Under threat predominantly from the potential 

  • introduction of mammalian predators to islands where it breeds
  • the loss of its natural tussac habitat by burning and livestock grazing
  • cannot survive on islands in the presence of rats
    • may co-exist with a few domestic cats on larger islands
    • feral cats and rats have probably already destroyed whole populations

Species detail

Endemic to the Falkland Islands, Cobb’s wren is larger than closely related species in the Americas and has markedly different habits.

It survives on small islands free of introduced predators and with native tussac grass habitat.  Its population is stable, but vulnerable.
