[3] The blue-and-white mockingbird is a year round resident of Mexico from south of the Isthmus of Tehuantepec through Guatemala to El Salvador and southern Honduras.

[3] The blue-and-white mockingbird primarily forages on the ground, by sweeping aside leaf litter with its bill.

Though its diet has not been fully documented, its primary food appears to be invertebrates and it also eats small fruits.

Females build the nest, a shallow cup of fibrous roots on top of a platform of sticks.

The blue-and-white mockingbird's song has been described as "an amazing medley of bird notes...[including] a rapid series of monosyllables, now a shrill squeak, now a whistle, now a guttural croak...certainly not musical or harmonious".
