Land-based observations of cetaceans and a review of recent strandings at subantarctic Macquarie Island

A comprehensive study reveals that most cetacean species are relatively uncommon in the inshore waters of Macquarie Island. Over 391 systematic one-hour observation periods spanning 59 weeks in 2002 and 2003, nine species were identified, with killer whales, long-finned pilot whales, and sperm whales detected with some frequency. The remaining species were observed only once, indicating limited presence near the island. Additionally, eight previously unpublished stranding records are summarized, contributing to the understanding of marine megafauna in the region. The study underscores the importance of routine archiving of cetacean sightings from shipping activities to enhance knowledge of this subantarctic ecosystem.
