克布氏鷦鷯

Cobb's wren (Troglodytes cobbi) is a small, insectivorous passerine in the family Troglodytidae, endemic to the Falkland Islands (Islas Malvinas) in the South Atlantic Ocean. It inhabits rocky coastal areas, kelp beds, tussac grass tussocks, and rocky shorelines, where it forages actively for invertebrates, amphipods, and small crustaceans among rocks and beach wrack. Cobb's wren is closely related to the house wren complex but represents a distinct island lineage adapted to maritime conditions. Its distribution is restricted to the outer islands of the Falklands, as introduced rats and cats have extirpated it from most inhabited islands and the two main islands where introduced predators are present. On rat-free outer islands, populations are locally common. The IUCN assesses Cobb's wren as Least Concern overall, acknowledging that total population size across the outer islands is considered adequate, though its restricted island endemic range and vulnerability to mammalian predator introduction demand ongoing management. Rat eradication programmes on Falkland Islands have been crucial in protecting this and other seabird-associated species.
