 Juvenile robins and eggs are preyed upon by squirrels, snakes, and some birds, such as blue jays, California scrub jays, Steller's jay, common grackles, American crows, and common ravens.Adults are primarily taken by "Accipiter" hawks, cats, and larger snakes (especially rat snakes and gopher snakes).Mammals such as foxes and dogs are mainly likely to grab fledgling young robins from the ground, while raccoons often prey upon nests and small carnivores such as American martens, ring-tailed cats and long-tailed weasels are agile enough to hunt adults.
