Orange-bellied Antwren is a perching bird in the family Thamnophilidae (order Passeriformes) — Terenura sicki, recorded as Critically Endangered and tied to Brazil.
Appearance
Adult males' crown, nape, and upper back are streaked black and white. The rest of their upperparts are black with a few white streaks. They have a hidden white patch between the shoulders. Their wings are black with pale edges on the flight feathers and wide white tips on the coverts.
The orange-bellied antwren is 9.5 to 10.5 cm (3.74 to 4.13 in) long and weighs 6.5 to 7 g (0.23 to 0.25 oz).
Published measurements include mass about 7.
Range and habitat
The orange-bellied antwren has a disjunct distribution in the northeastern Brazilian states of Pernambuco and Alagoas. It inhabits the subcanopy and canopy of semi-humid evergreen forest. In elevation it mostly ranges between 200 and 700 m (660 and 2,300 ft) but occurs as low as 100 metres (330 ft).
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet and breeding
The orange-bellied antwren's diet is not known in detail but is mostly insects and probably includes spiders. It forages singly, in pairs, or in family groups, and often though not habitually as part of a mixed-species feeding flock.
It actively and restlessly gleans its prey in dense vegetation, mostly in vine tangles. The orange-bellied antwren's breeding season is thought to span from November to February. Its nest is a small cup of moss and fungal fibers, hung from a fork near the end of a branch typically about 10 to 12 m (30 to 40 ft) above the ground.
