Ringed Antpipit

The ringed antpipit is 13.5 to 14 cm (5.3 to 5.5 in) long and weighs 15 to 18 g (0.53 to 0.63 oz). The sexes have the same plumage; males are larger than females. Adults of the nominate subspecies have a grayish brown crown, a faint whitish loral spot, and a faint whitish spot behind the eye on an otherwise pale grayish olive face. Their upperparts, wings, and tail are dark brownish olive. Their chin and throat are white. Their underparts are mostly white with an almost solid black "necklace" on the breast that gives the species its English name. Voice: The ringed antpipit has somewhat variable songs, which is unusual for a flycatcher. A typical pattern is "a rusty rising-falling (sometimes descending or quavering) whistle followed by a longer descending whistle: HEE'U-huEEU." The song can be preceded, followed, or interrupted by "short pit or rattle notes".
