A highly distinctive bird within its relatively small range, the strikingly long-tailed Blue-and-white Mockingbird is just that. The entire upperparts are deep blue, except for the black mask, while below the bird is all white, with the exception of the blue gray flanks and vent. It was sometimes considered to be conspecific with Blue Mockingbird (Melanotis caerulescens), which ranges further north in Mexico, while Blue-and-white Mockingbird occurs from southeastern Mexico to northern El Salvador. It occupies a variety of wooded vegetation types, from semi-arid areas to highland pine-oak forest. Blue-and-white Mockingbird is a largely insectivorous, but also feeds on small fruits, for which it forages mainly on the ground.
