“…This is the most common haplotype among Andrew's beaked whales sampled to date (48%; 10 of 21 animals from throughout the species' range; M. Dalebout, in preparation). The second most common haplotype differs from this by 4 bp and is shared by 7 animals (33%) with a similarly wide distribution, including one animal from Uruguay (HM367089; Laporta et al , 2005). The other two haplotypes known are intermediates between the two common haplotypes.…”

Beaked whale strandings on the Falkland Islands and South Georgia, South Atlantic Ocean, between 1866 and 2008

Records of beaked whales stranded in the Falkland Islands and at South Georgia were collated for the period 1866 to 2008. Thirty-eight records, involving at least seven species in four genera, were documented. Strap-toothed whales (Mesoplodon layardii Gray, 1865) were the most common species with 11 records, including two neonates. Andrews' beaked whales (M. bowdoini Andrews, 1908), Arnoux's beaked whales (Berardius arnuxii Duvernoy, 1851), Cuvier's beaked whales (Ziphius cavirostris Gray, 1823), Gray's beaked whale (M. grayi van Haast, 1876), Hector's beaked whales (M. hectori Gray, 1871) and southern bottlenose whales (Hyperoodon planifrons Flower, 1882) were recorded on three to five occasions. In several cases, records suggested potential temporal changes in range. For example, Arnoux's beaked whale has not been recorded in the Falkland Islands since 1965, whilst Gray's beaked whale was not recorded prior to 1981, and Andrews' beaked whale was not recorded before 1987. Although the number of records for each species is low, this could reflect changes in water temperatures and/or prey availability. Overall, this study confirms that the Falkland Islands–Tierra del Fuego region is one of the world's key areas for beaked whales.

“…Andrews' beaked whale is known from 37 published records, and from these, the species appears to have a circumpolar distribution north of the Antarctic Convergence to 32°S (Baker, 2001; Laporta et al , 2005; MacLeod et al , 2006). This study adds a further record to the two known records for the Falkland Islands.…”

“…For the specific determination of specimen MNHN/ MAM 1972, comparisons were made with the descriptions and morphometric data of adult specimens of M. hectori, M. peruvianus, M. densirostris, M. bowdoini, M. perrini, M. stejnegeri, M.grayi, and M. europaeus (Ross 1970;Venegas and Sielfeld 1978;Sielfeld 1979;1983, Lichter 1986Mead and Baker 1987;Nobuyuki et al 1987;Mead 1989;Baker and Helden 1999;Norman and Mead 2001;Zerbini and Secchi 2001;Dalebout et al 2002;Capazzo et al 2005;Laporta et al 2005).…”

Information collected from a complete female juvenile individual of Gray's beaked whale (Mesoplodon grayi) stranded on the Guanaqueros coast, Coquimbo Region in Chile (30°S) is provided. Difficulties to differentiate specimens of Gray's beaked whale and Hector’s beaked whale (M. hectori) are discussed based on the use of diagnostic phenotypic characters, such as differences in color patterns and position of teeth on the lower jaw. The identification of the studied specimen as Gray's beaked whale was supported by a detailed review of cranial characters and molecular analyses. Finally, we provide an updated list containing all known Chilean records for this species.

“…Note however that the ZM specimen numbers listed in table 1 of that publication are incorrect. The only other records of Andrew's beaked whale from the South Atlantic are two individuals from strandings in the Falkland Islands (Baker, 2001) and a stranded animal from Tierra del Fuego, Argentina and one from Uruguay (Laporta et al, 2005). …”

The cetacean fauna at the Tristan da Cunha archipelago has been assessed from ship-based, aerial and land-based observations from 1983-2000, from strandings on Tristan da Cunha and Inaccessible Island between 1983 and 1995, and from whaling catch data from 1934 -1967. Five species (Eubalaena australis, Megaptera novaeangliae, Tasmacetus shepherdi, Globicephala melas and Orcinus orca) have been sighted within the territorial waters of the archipelago, eight species (Balaenoptera physalus, B. borealis, B. acutorostrata/bonaerensis, Physeter macrocephalus, Mesoplodon mirus, M. bowdoini, Delphinus sp. and Lissodelphis peronii) have been seen or taken within 200 nautical miles (360 km) of the group or have been found stranded on its shores, while another two species (Caperea marginata and Lagenorhynchus obscurus) have been recorded close enough to be considered likely to occur within 200 nautical miles. The records of Mesoplodon mirus and M. bowdoini represent significant extensions to their known distribution. Apart from its possible importance as a mid-oceanic nursery area for southern right whales, the waters of the Tristan Archipelago seem to be a concentration area for T. shepherdi, one of the least-known of the world's cetaceans.
