Agreement on the Conservation of Albatrosses and Petrels

ACAP Breeding Sites No. 18. Albatross Island, Bass Strait, home of Australia’s endemic Shy Albatross

 

Access to Albatross Island is a 35-km boat ride across the confused, and often treacherous, waters of the Bass Strait from northern Tasmania. The island is one of only three breeding localities for Australia’s endemic and Vulnerable Shy Albatross Thalassarche cauta. The 18-ha island is a Tasmanian State Nature Reserve and part of an Important Bird Area. Currently no public access is allowed to the Albatross Island Nature Reserve to protect the breeding environment of the Shy Albatross.

 

A large cave system runs much of the length of Albatross Island and provides some protection from the elements for researchers.

 

The largest colony on Albatross Island, unimaginatively named “Main Colony”, contains over 3000 breeding pairs of Shy Albatrosses each year.

Exploited for its feathers to near extinction in the 1800s, the population on Albatross Island has gradually recovered from as few as two or three hundred to the current 5200 breeding pairs. The island is also a breeding site for Short-tailed Shearwaters Puffinus tenuirostris and Fairy Prions Pachyptila turtur, among several other seabird species.

Four young Shy Albatrosses practice their courtship routines on one another. Shy Albatrosses return to their colony as young as three years of age, but typically do not commence breeding until at least seven or eight years old.
