description

The Rio-de-Janeiro ant panties reach a size of 9.5 cm. The male is lead-colored with a black bib that extends to the upper abdomen. The wings are black with white spots on the ceiling. The black tail is not marked. The slender beak is dark. The female has a gray head. The throat is lighter. The top is light buff-reddish brown. The tail is more brightly colored. The underside of buff-reddish brown. The voice consists of nasal " kíu " sounds.

Habitat and way of life

Little is known about his way of life. The type specimen from 1982 was discovered in a partially isolated and severely disturbed forest parcel. The following observations in the Reserva Ecologica de Guapi Acu were in a young secondary forest at an altitude between 35 and 200 m. Most commonly, the birds have been observed in mixed flocks with other insectivorous bird species, including the southern monochrome ant hatchet ( Myrmotherula unicolor ). When foraging for food, it hangs less than two meters above the ground between the dense vine roots.

status

The Rio de Janeiro ant hatchers are known only from the holotype from 1982, which was collected at Santo Aleixo near the municipality of Magé in central Rio de Janeiro. Evidence from the Reserva Ecologica de Guapi Acu from 1994 onwards is inconclusive, as the species cannot be distinguished from the white-flanked ant hatchback ( Myrmotherula axillaris ), which occurs in the same region, in terms of song . Presumably, the Rio de Janeiro ant catcher could be a hybrid of white flank ant hatchers and southern monochrome ant hatchers ( Myrmotherula unicolor ) or a local morph of the white flank ant hatchers.
