Life History, Abundance, Activity, and Special Behaviors
The California Tiger Salamander engages in nocturnal breeding migrations. Movement occurs from dry season refuge sites to the breeding ponds from November to April, thought most commonly from December to March. These migrations don't occur until the ground has become moist, because the breeding pools do not form until the soil below them becomes saturated from the autumn rains. Males precede females to the breeding sites, and males often outnumber females at these sites. Shortly after breeding, the adults vacate the ponds. Eggs are deposited singly or in small groups of 2-4, submerged in the relatively shallow depths of the temporary pools. A minimum of 10 weeks is required for complete development (including metamorphosis).
