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 →

Rare
Under 5% of wildlife watchers report a Sooty Oystercatcher sighting in Sydney on a given day, based on 501 verified sightings from GBIF citizen-science data. It is the 101st most-seen of the 243 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, 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 Oystercatcher in Sydney 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 Oystercatcher sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Sooty Oystercatcher sightings, Sydney has the highest daily chance: under 5%. Next come Melbourne (Australia, under 5%) and Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Sooty Oystercatcher is recorded against all the birds logged in Sydney (501 verified sightings), 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.
