Southern Antpipit

The southern antpipit is 13 to 14 cm (5.1 to 5.5 in) long and weighs 14 to 18 g (0.49 to 0.63 oz). The sexes have the same plumage. Adults have a grayish olive 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 olive. Their chin and throat are creamy white. Their underparts are mostly white with an almost solid black "necklace" on the breast from which black streaks extend along the flanks. The flanks also have a grayish olive wash. Juveniles resemble adults. Voice: The southern antpipit's song is a "very high, short, calm, sweet series 'weeh-rrwee-wurr-wiwi' ('rrr' very short, canary-like trills)".
