Ihering's Antwren

Ihering's antwren is 8.5 to 9.5 cm (3.3 to 3.7 in) long and weighs 7.5 to 9 g (0.26 to 0.32 oz). It is a smallish bird with a shortish tail. Adult males of all three subspecies have dark gray upperparts with a hidden white patch between the shoulders. Their wings are dark gray with white-tipped black coverts. Their tail is dark gray. Their lower cheeks, throat, upper breast, and center of their lower breast are black. The rest of their underparts are a paler gray than the upperparts except for a whitish center to the belly. Adult females of the nominate subspecies have blue-gray upperparts. Voice: The songs of the three subspecies of Ihering's antwren differ somewhat, but are generally "a countable series of intense, downslurred 'peer' notes". The song of subspecies M. i. oreni is higher pitched than those of the other two subspecies. The subspecies' calls are apparently alike, "a disyllabic 'pe-weet', second syllable a sharp downslurred whistle".
