Up until recently the mockingbirds of the Galapagos were considered to form a separate genus, Nesomimus. Now molecular data confirms that they are imbedded within typical Mimus, so they have been shifted to this typical mockingbird genus. This species is the only one that is found on multiple islands in the archipelago, the others all being single-island endemics. Molecular data suggests that the current organization of the Galapagos Mockingbird may be a simplification. Within the Galapagos Mockingbird there are three groups based on DNA. The first is the main one in the central islands, second is a group on Isabela - Fernandina (the Western Islands) and finally the subspecies bauri from Genovesa is allied to the Española and San Cristobal mockingbirds! More work is needed to determine the species level taxa in the Galapagos Mockingbird. The Galapagos Mockingbird is common in the dry lowlands of the larger islands, particularly in the cactus zone and it adapts well to urbanization, being relatively common in Puerto Ayora on Santa Cruz Island for example. It is usually seen in pairs, or even singles, although after the breeding season family groups are commonly encountered.
