Similar Species
The pattern in the adult tail is distinctive against similar species if seen well.
Distribution
Breeds around south-eastern Australia, Tasmania, and New Zealand. One of the best places to view them is at the breeding colony at Muriwai, North Island, New Zealand, where there are observation platforms and interpretive displays.
In non-breeding season spreads further west and north along Australias coast, but some birds will be found at the colony at any time of the year.
Taxonomy
This is a monotypic species[1].
Habitat
Mostly stay in coastal waters year-round.
Behaviour
Feeding
Australian Gannet often dives from quite high up, plunging into the water head first, and often does so in flocks that go for schools of fish.
Flight
In direct flight, they often travel in lines with alternating glides and easy wingbeats. Often will rest on the water if not too rough.
Breeding
Breeds on small islands, but is trying to establish a mainland colony in Australia (Pizzey and Knight, 1997).
