Appearance
This antwren is a small, short-tailed passerine bird growing to a length of about 9.5 cm . The male is similar in morphology to the Amazonian streaked antwren and the Guianan streaked antwren, having black upper parts streaked with white, two white wingbars and white underparts streaked with black. The female is also similar to the females of those two species, but has a more orange-rufous head, dark streaking on the crown, and unstreaked buff underparts. The Pacific antwren is not likely to be confused with those two species as it is found exclusively west of the Andes, while they only occur to the east. The song is a fast, lively series of staccato notes, ascending slightly in pitch. Other calls include "chee-cher" and "chee-pu", uttered by both sexes.
Distribution
The Pacific antwren is native to Panama and Colombia and Ecuador west of the Andes Mountains, ranging as far south as Azuay Province at altitudes normally less than 800 m . It is found in damp rainforests, at the edges of woodland, in glades and in gardens, foraging for insects in the sub-canopy of trees, and often far from watercourses.Status
''M. pacifica'' has a very wide range and is able to adapt to living in secondary forest. It is a fairly common bird with a stable population size and the International Union for Conservation of Nature has assessed its conservation status as being "least concern".Habitat
