White-bellied Antbird

The white-bellied antbird is about 15 cm (5.9 in) long and weighs an average of about 28 g (0.99 oz). Adult males of the nominate subspecies M. l. longipes have a cinnamon rufous crown, upperparts, wings, and tail. They have a hidden white patch between their scapulars. Their lesser wing coverts have white or pale buff edges and sometimes cinnamon tips. The sides of their head, their throat, and their upper breast are black and bordered with slate gray. Their lower breast and belly are white, their flanks tawny or buffy, and their undertail coverts tawny. Voice: The male white-bellied antbird's song is "a bright, ringing crescendo of 15-25 loud, rapid jeer notes...descending, trailing off, and ending in a few chew notes on same pitch". Females sing a similar though shorter song. The species' calls include "a short, liquid rattle" and a "long...thin, downslurred whistle, sometimes abbreviated".
