Site summary
The Rosenthal Islands are located off the western coast of Anvers Island, in the Palmer Archipelago, Antarctic Peninsula, at 64°36'S 64°15'W. The site was first formally recognised for its exceptional ecological and scientific values when it was designated as a Restricted Zone under Antarctic Specially Managed Area (ASMA) No.7 Southwest Anvers Island and Palmer Basin. The original IBA qualified on the basis of a Gentoo penguin (Pygoscelis papua) colony located on a peninsula ~5 km south of the Rosenthal Islands (incorrectly identified as an islet in the original description). New data on breeding birds and other ecological values in the area were collated over 2016-20, resulting in a new Antarctic Specially Protected Area (ASPA) proposed for designation under the Antarctic Treaty System (designation had to be deferred when the 2020 Antarctic Treaty meeting was cancelled and will be considered in 2021). The IBA qualifies on the basis that the Gentoo penguin (Pygoscelis papua) colony meets Criterion A4 and the IBA is defined by the boundary of the ASPA management unit.
