Dusky Antbird

This is a common bird in the understory thickets of wet forest, especially at edges and clearings, and in adjacent tall second growth. The female lays two reddish-brown-spotted white eggs, which are incubated by both sexes, in a small, deep, plant fibre and dead leaf cup nest, which is suspended from the fork of a thin branch or vine low in a tree. The male and female parents both feed the chicks.

The Dusky Antbird is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

Dusky antbirds are members of the suboscine passerine family Thamnophilidae, a species-rich neotropical group (Sibley and Monroe, 1990Go). Pairs defend territories year-round in brushy forest edge habitat where they forage 0.5-10 m up in vines, and vine-covered tree branches, shrubs, and grass. Nests are small (ca 23 cm long) bags made of black rhizomorphs (fungal "horsehair"), suspended 1-4 m above the ground from the end of vertical vines or bamboo shoots (Chusquea spp. More

some, such as the Dusky Antbird, can take as long as 20 days. The altricial chicks are born naked and blind. Both parents brood the young until they are able to thermoregulate, although, as with incubation, only the female broods at night. In common with many songbirds, the parents take faecal sacs for disposal away from the nest. Both parents feed the chicks, often bringing large prey items. When the chicks reach fledging age, after 8–15 days, attending parents call their chicks. More

The Dusky Antbird or Tyrannine Antbird, Cercomacra tyrannina, is a passerine bird in the antbird family. It is a resident breeder in tropical Central and South America from southeastern Mexico southwards to western Ecuador, and Amazonian Brazil. This is a common bird in the understory thickets of wet forest, especially at edges and clearings, and in adjacent tall second growth. More

The Dusky Antbird is typically 14.5 cm long, and weighs 18 g. The adult male is mainly blackish-grey above and paler grey below, with two white wing bars. The female has brown upperparts and rufous-cinnamon underparts. Young birds, especially males, are darker than the adults. Exact plumage shades vary geographically, since there are a number of subspecies of this antbird. More
