Habitat

Behavior

  • All three jay species are omnivores.Most of their diet is plant matter, including pinyon pine seeds, berries, and other nuts.During the summer, all 3 species feed heavily on insects, lizards, and the eggs of other birds.
  • All three species will steal unattended food and table scraps from humans. Please store food carefully to keep these crafty animals from feeding on unhealthy and unnatural human food.
  • Scrub jay and pinyon jay nests are baskets of twigs lined with grass, hair, and plant fibers. Steller's jay nests are made of twigs, moss, bark, and leaves held together with mud.
