The San Cristóbal mockingbird or Chatham mockingbird, is a species of bird in the family Mimidae. It is endemic to San Cristóbal Island in the Galápagos Islands.
Region
Galápagos Islands
Typical Environment
Occurs across arid and semi-arid zones of San Cristóbal Island, favoring coastal scrub, lava fields, and dry woodland. It is commonly associated with Opuntia cactus stands and open shrublands where ground cover is sparse. The species uses edges of mangroves and beaches for foraging, especially along tide lines. It is largely terrestrial in its daily movements but roosts and nests in shrubs and low trees.

Diet
Opportunistic omnivore feeding on insects, spiders, and other arthropods gleaned from the ground and low vegetation. Consumes fruits and nectar, especially from Opuntia cacti, and will take seeds when available. It also scavenges, occasionally taking carrion or eggs during shortages.
Preferred Environment
Forages mostly on the ground in open scrub, lava flats, and coastal strand lines. Frequently feeds around cactus groves and along beach edges where tidal debris concentrates invertebrates. Will also search low shrubs and human-altered edges for food.
