Speckled Antshrike

The speckled antshrike is 13 to 16 cm (5.1 to 6.3 in) long; one female weighed 24.6 g (0.87 oz). The species exhibits some sexual dimorphism, though both sexes have a gray and black bill with a hook at the end like true shrikes. They also have short black bristles on their lores, below their eyes, at the base of the bill, and on their chin. Adult males have a dark gray forehead. Their crown, nape, back, and scapulars are olive brown to buffy brown; the scapulars have brown tips. The feathers of their upperparts have black edges and tips that appear as dark lines. Voice: The speckled antshrike's song is "a series of evenly spaced, high pitched notes, the series rising steadily in pitch". When singing voluntarily it typically makes five notes; when challenged by a recording it may sing between three and 12 notes. The species is not highly vocal, but both sexes sing, with the female's song being slower, shorter, and slightly lower pitched than the male's.
