Mimus saturninus
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. Voice: The chalk-browed mockingbird's song is loud, a "varied series of notes, trills, phrases". Its calls include a "sharp and penetrating 'tshrip'" and a "snorting sha-sha-sha". It often mimics other species including some raptors.

Northern Mockingbird
Mimus polyglottos
The northern mockingbird is a medium-sized mimid that has long legs and tail. Males and females look alike. Its upper parts are colored gray, while its underparts have a white or whitish-gray color. It has parallel wing bars on the half of the wings connected near the white patch giving it a distinctive appearance in flight. The black central rectrices and typical white lateral rectrices are also noticeable in flight. The iris is usually a light green-yellow or a yellow, but there have been instances of an orange color. The bill is black with a brownish black appearance at the base. Voice: Although many species of bird imitate the vocalizations of other birds, the northern mockingbird is the species best known in North America for doing so.
