Slaty Antwren Myrmotherula schisticolor Scientific name definitions

The Slaty Antwren is found from southeast Mexico to northern Venezuela, and throughout the tropical Andes to northwest Bolivia; as such, it is the most widely distributed Myrmotherula outside of Amazonia. Its morphology and vocalizations suggest a close relationship with the Rio Suno Antwren (Myrmotherula axillaris), and the Salvadori’s Antwren (Myrmotherula minor), both of which are extremely localized species, in upper Amazonia and southeast Brazil, respectively. Males are similar to those of both of the two last-named species, but are overall darker in coloration, with smaller white wing spotting, while females are rather brighter, more cinnamon, especially below, but show a fair degree of geographical variation between the three different subspecies. The Slaty Antwren occurs in the understory of montane and foothill forests, between at least 600 and 2400 m.
