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...

Likely
About 40% of wildlife watchers report a Blackish Cinclodes sighting in Falkland Islands on a given day, based on 1,127 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 80% of wildlife watchers report a Blackish Cinclodes in Falkland Islands on a given day, against about 40% in June, October and December–March, the lowest months.
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.
Yes
Of the 2 parks where we can rate Blackish Cinclodes sightings, Falkland Islands has the highest daily chance: about 40%. Next come Tierra del Fuego National Park (Argentina, under 5%).
Same order: Passeriformes
The closest relatives of the Blackish Cinclodes that you can see in Falkland Islands (order Passeriformes, Perching Birds) are Austral Thrush (about 70%), Dark-faced Ground-Tyrant (about 60%) and Long-tailed Meadowlark (about 50%), 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 Falkland Islands (1,127 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.
