The sooty shearwater (Ardenna grisea) is a medium-large shearwater in the seabird family Procellariidae. In New Zealand, it is also known by its Māori name tītī, and is harvested by Māori people for muttonbird, like its relatives the wedge-tailed shearwater (A. pacificus) and the Australian short-tailed shearwater (A. tenuirostris).
The sooty shearwater was formally described in 1789 by the German naturalist Johann Friedrich Gmelin under the binomial name Procellaria grisea. The shearwater had been briefly described in 1777 by James Cook in the account of his second voyage to the Pacific, but without a valid scientific name; and also in 1785 the English ornithologist John Latham had described a museum specimen, again without giving it a scientific name. The sooty shearwater is now placed in the genus Ardenna, that was described in 1853 by Ludwig Reichenbach. The genus name Ardenna was used to refer to a seabird by Italian naturalist Ulisse Aldrovandi in 1603, and the specific epithet grisea is medieval Latin for "grey". The species is considered to be monotypic; no subspecies are recognised.
It appears to be particularly closely related to the great shearwater (A. gravis... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sooty Shearwater sighting in Wadden Sea National Park on a given day, based on 61 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 205th most-seen of the 285 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sooty Shearwater in Wadden Sea National Park on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sooty Shearwater sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
16th of 21
Of the 21 parks where we can rate Sooty Shearwater sightings, Wadden Sea National Park ranks 16th at under 5%. The best odds are in Kenai Fjords National Park (United States, about 20%), Rakiura National Park (New Zealand, about 10%) and Machalilla National Park (Ecuador, about 10%).
GBIF citizen-science records
It is estimated from how often the Sooty Shearwater is recorded against all the birds logged in Wadden Sea National Park (61 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
