Pacific Antwren Myrmotherula pacifica

  • © Hawk Person

The range of the well-named Pacific Antwren extends from Panama (where it also occurs on the country’s Caribbean slope) to western Ecuador, and the species occurs in the lower stories of lowland and foothill forests to 1300 m, although it is usually confined to elevations below this. Until recently, the Pacific Antwren was considered to be conspecific with the Guianan Streaked-Antwren (Myrmotherula surinamensis) and the Amazonian Streaked-Antwren (Myrmotherula multostriata), and these three species are clearly rather similar in overall plumage patterns. Fortunately, for identification purposes, there is no geographical overlap between them. Males of the present species are basically heavily streaked black, gray, and white birds, with two white wingbars, while females are decidedly more attractive, having a pale orange head and underparts, a black and white-streaked mantle, and black wings also marked by two white covert bars.
