The star-throated antwren (Rhopias gularis) is an insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to southeastern Brazil. The star-throated antwren was described and illustrated by the German naturalist Johann Baptist von Spix in 1825 and given the binomial name Thamnophilus gularis. It was subsequently placed with the "stipple-throated group" in the genus Myrmotherula, a group which later was itself transferred to genus Epinecrophylla. When a morphological and genetic analysis published in 2012 found that the star-throated antwren was not closely related to other species in Myrmotherula it was moved to genus Rhopias which had originally been erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860. The type species is the star-throated antwren. The name of the genus comes from the Ancient Greek word rhōps meaning "bush".
The star-throated antwren is the only member of genus Rhopias and it has no subspecies. Its closest relatives appear to be the banded antbird (Dichrozona cincta) and the two species of antwrens in genus Isleria. The star-throated antwren... Wikipedia →

Rare
Under 5% of wildlife watchers report a Star-throated Antwren sighting in Tijuca National Park on a given day, based on 93 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 106th most-seen of the 214 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.
February, April and June
In those months about 10% of wildlife watchers report a Star-throated Antwren in Tijuca National Park on a given day, against under 5% in March, May and July–January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Star-throated Antwren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Star-throated Antwren sightings, Tijuca National Park ranks 3rd at under 5%. The best odds are in Serra dos Órgãos National Park (Brazil, about 40%) and Itatiaia National Park (Brazil, about 20%).
Same family: Thamnophilidae
The closest relatives of the Star-throated Antwren that you can see in Tijuca National Park (family Thamnophilidae, Typical Antbirds) are Chestnut-backed Antshrike (about 20%), Rufous-margined Antwren (about 20%) and Plain Antvireo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Star-throated Antwren is recorded against all the birds logged in Tijuca National Park (93 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.
