Magdalena Antbird

The Magdalena antbird is 13 to 16 cm (5.1 to 6.3 in) long; one male weighed 24 g (0.85 oz). Adult males have a slaty head and neck. Their upper back is brown with a usually hidden white patch between their scapulars. Their wings are brown; their wing coverts are black with buff and white dots. Their lower back, rump, and tail are chestnut. Their throat is black, their flanks and lower belly brown, and the rest of their underparts slate-gray. Adult females are similar to males but with a black and white checkered throat and buff (not white) dots on their wing coverts. Voice: The male Magdalena antbird's song is described as similar to that of its former "parent" dull-mantled antbird, which is "a countable series...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".
