Cercomacra

Cercomacra is a genus of insectivorous birds in the antbird family, Thamnophilidae. The genus is found in South America and consists of several species, all of which are characterized by their relatively small size and long tails. These birds are typically found in dense undergrowth, particularly in humid forests, and are often observed foraging for insects on the ground or in low vegetation.

Species within the genus Cercomacra are generally sexually dimorphic, with males and females exhibiting different plumage. Males are often predominantly black or dark gray, sometimes with white markings, while females tend to be browner or rufous. Their vocalizations are also important for species identification, consisting of distinct songs and calls. The diet primarily consists of insects, spiders, and other small invertebrates, which they catch by gleaning or sallying from perches.

The conservation status of Cercomacra species varies. Some species are considered common and widespread, while others are more restricted in their range and may be vulnerable to habitat loss and degradation due to deforestation and agricultural expansion. Research on the genus continues to explore their behavior, ecology, and evolutionary relationships within the Thamnophilidae family.
