The blackish cinclodes (Cinclodes antarcticus) is a Near Threatened passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found on Tierra del Fuego and the Falkland Islands, where it is known as the tussac-bird or tussock-bird.
The blackish cinclodes' taxonomy is unsettled. BirdLife International's Handbook of the Birds of the World (HBW) treats the two taxa as separate species, retaining "blackish cinclodes" for antarcticus and calling maculirostris the "black cinclodes".
This article follows the one-species, two-subspecies, model. The blackish cinclodes is 18 to 23 cm (7.1 to 9.1 in) long and weighs about 63 g (2.2 oz). The sexes have the same plumage. Adults of the nominate subspecies are mostly dark sooty brown, with a slightly paler throat and some dull rufous on the base of the flight feathers. The last is usually visible only in flight. Its iris is dark brown, its bill blackish, and its legs and feet blackish. Juveniles... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blackish Cinclodes sighting in Tierra del Fuego National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 74th most-seen of the 78 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Blackish Cinclodes in Tierra del Fuego National Park on a given day, so our monthly data shows no clear season. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blackish Cinclodes sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tierra del Fuego National Park, in our data
Tierra del Fuego National Park is the only park on Wallace's Line with enough records to rate Blackish Cinclodes sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Cinclodes
The closest relatives of the Blackish Cinclodes that you can see in Tierra del Fuego National Park (genus Cinclodes) are Buff-winged Cinclodes (about 10%), Dark-bellied Cinclodes (about 10%) and Gray-flanked Cinclodes (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blackish Cinclodes is recorded against all the birds logged in Tierra del Fuego National Park (8 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.
