Mocking birds are known for their singing skills. They mimic the sounds of other amphibians, insects, etc., in quick succession and loudly. Also called the southern mockingbird, it has a huskier voice than the northern mockingbird (M. polyglottos), its close cousin. The Socorro mockingbird (M.graysoni) is also close to these birds.
The tropical mocking birds are gray on their upperparts, head, and they are off-white on underparts. They have a white eye stripe and yellow eyes, with a dark color patch running through the eye.
The wings are blackish with two distinct wing bars and white edges on flight feathers. Their tail is long, dark with white feather tips, a small bill with a downward curve, and their legs are dark and long.

The male mockingbird, known for its singing, sings different songs (as many as 200 songs!) to attract the female for mating.
It would be interesting to note that an unpaired mockingbird sings all through the night, displaying its impressive vocal range, to attract a female for breeding, at the risk of predation. Thus, the song is a vital part of mating. Scientists have also discovered that male singing resets the reproductive system of females.
The female clutch is, usually, three grayish-green eggs in a twig nest. The incubation period is about 13 to 15 days, which is done by the female only. After that, parenting is done by both males and females. They both defend the nest and eggs aggressively attack predators such as other birds and animals like dogs and iguanas.
The male eventually takes overfeeding and teaches the nestlings to fly while the female works on other nests and brooding.
