About the Chalk-browed Mockingbird
The chalk-browed mockingbird (Mimus saturninus) is a bird in the family Mimidae. It is found in Brazil, Bolivia, Argentina, Paraguay, Suriname, and Uruguay. The chalk-browed mockingbird has four subspecies: the nominate Mimus saturninus saturninus, M. s. arenaceus, M. s. frater, and M. s. modulator.
The chalk-browed mockingbird is 23.5 to 26 cm (9.3 to 10.2 in) long and weighs 55 to 73 g (1.9 to 2.6 oz). Males are slightly larger than females. Adults of the nominate subspecies have a dark brown crown, a broad white supercilium, a blackish line through the eye, and white cheeks. Their upperparts are brownish with some darker streaks; the rump is buffier. Their wings are blackish and show two obscure bars when folded. The tail is also blackish; most feathers have white tips and the outermost have white edges. The underside of their body is white from the throat to the vent, though the breast has a gray tinge and the flanks are buffy with faint dark streaks. The juvenile is browner than the adult and has buffier underparts with dark streaks on the breast.
