[4] Except in Jamaica, the Bahama mockingbird inhabits a variety of biomes including coastal strand, semi-arid scrub, open woodland, and plantations.

It appears to favor taller, denser vegetation than the similar northern mockingbird (Mimus polyglottus) where their ranges overlap.

[4] The Bahama mockingbird is omnivorous; its diet includes invertebrates, nectar, small fruits, and little lizards.

[4] The Bahama mockingbird's breeding season spans from February to July in most areas but from April on the Cuban islands.

Both sexes build a rough open cup nest of twigs, lined with softer fibers, and usually placed low in a bush.
