Rusty-winged Antwren

Herpsilochmus frater

The Rusty-winged Antwren, scientifically known as Herpsilochmus frater, is a diminutive bird, part of the Thamnophilidae family, often referred to as the "typical antbirds." This species exhibits a length ranging from 10 to 12.5 cm and a weight approximately between 10 to 12.5 g.

Identification Tips

Males of the nominate subspecies, H. f. frater, are characterized by a black crown and nape, a prominent white supercilium, and a black stripe through the eye. Their upperparts are ashy gray with black spots and streaks, and their wings are adorned with dark cinnamon red outer webs. Females, on the other hand, boast a rich chestnut-rufous crown and a buffy chestnut supercilium, with olive-gray upperparts and more pronounced white on the tail. Both sexes share a dark gray to brownish iris, a black maxilla, and a light gray mandible with a darker tip.


The Rusty-winged Antwren is found in the interior and edges of lowland and foothill evergreen forests, including terra firme and gallery forests. It prefers dense vine tangles and is typically observed from the forest's mid-storey to its subcanopy.


This species has a disjunct distribution across South America, with subspecies H. f. exiguus located in Panama and northwestern Colombia, and the nominate subspecies H. f. frater found from Colombia's Eastern Andes to northern Bolivia, and eastward through Venezuela, Guyana, Suriname, and Amazonian Brazil.


The Rusty-winged Antwren is considered a year-round resident within its range. It forages actively and methodically, often joining mixed-species feeding flocks and typically feeding between 8 and 30 meters above ground.

Song & Calls

The song of the Rusty-winged Antwren is a unique stuttered series of notes, starting with an accelerating sequence and shifting to a raspy rattle. Its calls include a descending rattled series and a short scolding note that varies tonally across its range.

Conservation Status

The IUCN, following HBW taxonomy, includes the Rusty-winged Antwren's subspecies in the assessment of the "northern rufous-winged antwren" and has classified it as Least Concern. The species is generally considered fairly common to common, with no immediate threats identified. It is found in many protected areas and extensive tracts of intact habitat.

Sense of Community
A great app, which is continually being improved. What really comes through is the passion of those behind the app. The sense of community is brilliant, so much help and support provided to new and/or in experienced birders.
Learning Birding with Birda
I’m relatively new to birding as a hobby, and Birda is a great way to keep track off all the species I see. I’m still working on my ID skills, but the app is great for figuring out potential species, and the online community is so friendly and helpful. Definitely recommend Birda to both early and serious birders! 🐦

Terrific App for Birders
Downloaded Birda around the time my interest in birding was sparked, and it has been a terrific app to help me (1) share my experience, (2) document my sightings, and (3) learn more about birds in general. That said, I also believe Birda is a fantastic app for birders of all experience levels. Great community!
