Short-tailed Shearwaters are medium-sized seabirds with an overall
dark-brown plumage.
The only exception from this homogeneous colour is the possibility
that some (not all) have grey or greyish-brown underwing coverts.
The legs and feet are grey. Their tail is short, with the feet
reaching the end of the tail or slightly beyond.

Short-tailed Shearwaters are a strongly migratory species.
In the southern autumn, Short-tailed Shearwaters migrate northwards,
from Australia/New Zealand to far-eastern Asia (in particular to Japan,
Kamchatka and the Aleutian islands), from where they will depart again
in the northern autumn, migrating southwards along the American West
coast, crossing the Pacific Ocean towards Australia, New Zealand and
the Southern Ocean in time for the next breeding season.
During the southern summer Short-tailed Shearwaters are usually found
in Australian waters, along the south coast of WA, SA, VIC, NSW and
along the east coast as far north as southern QLD. They are endemic
breeders that nest mostly on
offshore islands in
Bass Strait and along the coastline of Tasmania.
Short-tailed Shearwaters are found on the
open seas,
coastal waters
and, during their breeding season, on
offshore islands.

We first spotted Short-tailed Shearwaters off headlands at both Point Plomer,
Limeburners Creek NP,
and Crescent Head, NSW, in October 2013.
B. Hensen reports spotting Short-tailed Shearwaters off Cape Banks,
La Perouse, NSW, in November 2013.
At the time of the October/November 2013 sightings,
they were seen hunting closer to shore than normal, providing photo
opportunities from land. During the spring 2013 migration to their
breeding grounds in the south, many thousands of Short-tailed
Shearwaters did not make it and washed up on beaches.
We thank B. Hensen and A. Richardson for their help with the
identification of this species.
M. Eaton reports finding Short-tailed Shearwaters
on a pelagic off Eaglehawk Neck, near Hobart, TAS, in September 2021.
C. Pears spotted Short-tailed Shearwaters a few km off Adventure Bay,
Bruny Island, TAS, in January 2023.
