Dull-mantled Antbird

The dull-mantled antbird is 12.5 to 15.0 cm (4.9 to 5.9 in) long and weighs about 25 g (0.88 oz). Adult males have a blackish gray to slate-black head, neck, and upper mantle. The rest of their upperparts are dark reddish brown, chestnut, or olive with a usually hidden white patch between their scapulars. Their flight feathers and tail are blackish brown with dark reddish brown edges. Their greater wing coverts are dark reddish brown with cinnamon or rufous tips; their median and lesser coverts are black with white tips. Voice: The male dull-mantled antbird's loudsong is "a countable series (e.g., eight notes, over 1.8 seconds) of short notes that begins with three upslurred to flat notes and abruptly switches to five evenly paced downslurred notes, e.g., tsee tsee tsee, tyew-tyew-tyew-tyew".
