Migratory movements of humpback whales (Megaptera novaeangliae) between Eastern Australia and the Balleny Islands, Antarctica, confirmed by photo-identification
We report here migratory movements of three humpback whales (Megaptera novaeangliae) between Eastern Australia (E1 breeding grounds) and the Area V Antarctic feeding area in the vicinity of the Balleny Islands. Using photo-identification techniques, comparisons between a Balleny Island fluke catalog...

Using photo-identification techniques, comparisons between a Balleny Island fluke catalogue (n = 11 individuals), and existing fluke catalogues from Eastern Australia (n = 3120 individuals) and Oceania (n = 725 individuals), yielded three matches to Hervey Bay, Byron Bay and Ballina in Eastern Australia and no matches to Oceania.

The Oceania catalogue (n = 725) is made up of Tonga (n = 282); New Caledonia (n = 160); French Polynesia (n = 159); New Zealand (n = 41); Cook Islands (n = 36); American Samoa (n = 31); Vanuatu, Niue, Samoa and Fiji (n = 11) and Norfolk Island (n = 5).
