The sooty oystercatcher (Haematopus fuliginosus) is a species of oystercatcher. It is a wading bird endemic to Australia and commonly found on its coastline. It prefers rocky coastlines, but will occasionally live in estuaries. All of its feathers are black. It has a red eye, eye ring and bill, and pink legs.
John Gould described the sooty oystercatcher in 1845. Its species name is the Latin adjective fuliginosus, "sooty". Two subspecies are recognised, the nominate from the coastline of southern Australia and subspecies ophthalmicus from northern Australia. The southern subspecies is larger and heavier than the northern. The northern one, with a more yellowish eye ring, is found from the Kimberleys across the top of the country to Mackay in central Queensland. There is considerable overlap, as the southern subspecies has been found up to Cape York. Subspecies ophthalmicus has been thought distinctive enough to warrant species status and needs further investigation. Black redbill is a local name.
Measuring 42 to 52 cm (16.5 to 20.5 in) long with a bill length of 5–8 cm (2–3 in), the sooty oystercatcher has all black plumage, with pink-red legs and scarlet... Wikipedia →

With luck
About 10% of wildlife watchers report a Sooty Oystercatcher sighting in Rottnest Island on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 49th most-seen of the 81 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

Of the 10 parks where we can rate Sooty Oystercatcher sightings, Rottnest Island ranks 7th at about 10%. The best odds are in Freycinet National Park (Australia, about 40%), Wilsons Promontory National Park (Australia, about 40%) and Flinders Chase (Australia, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Sooty Oystercatcher is recorded against all the birds logged in Rottnest Island (31 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.
