Macquarie cormorant is a medium-sized seabird that lives only on Macquarie Island and nearby rocks in the Southern Ocean. It swims and dives excellently for prey.
Macquarie cormorant differs from other cormorants by its limited range and bright blue ring around the eyes. It is important for nature as part of the marine food chain and an indicator of ocean health around the island.
