DistributionRead full entry
Range DescriptionTroglodytes cobbi has a very scattered distribution in the Falkland Islands (Malvinas). Surveys in 1983/1984-1992/1993 indicated breeding on 12 offshore islands and islets, and estimated the total population at 1,300-2,400 pairs4. Surveys have indicated breeding on 35 islands7, and estimated the total population at 4,500-8,000 pairs3,5. Most of the islands are in small groups, separated by up to 64 km of sea, and there is no evidence to suggest an interchange between these island populations2,4. However, it is likely that dispersing immatures are able to cross small bays5. In 1983, sample plots on Kidney and Carcass Islands produced population densities of four territorial males per hectare in optimum habitat and two males per hectare in less suitable conditions5.
