The California tiger salamander (Ambystoma californiense) is an amphibian native to Northern California growing up to 8 inches long. California tiger salamanders migrate at night from upland habitats to aquatic breeding sites during the first major rainfall events of fall and early winter.
The California tiger salamander eats earthworms, snails, insects and fish.
Its numbers have dropped due to habitat loss, predation from crayfish and bullfrogs, being hit by cars during migration and interbreeding with the non-native tiger salamanders.
The California tiger salamander spends the summer underground in ground squirrel burrows. After the first few heavy rains in the fall, they come out of their burrows and migrate to breeding pools.
