Last night we had our first warm, rainy night of the spring and the salamanders and other amphibians were on the move.... that's why last night was salamander night.
Here is a photo of a Yellow-spotted Salamander crossing the road on that dark, rainy night.
Why were the Yellow-spotted salamanders risking their lives to get across the road? Well, on the other side of the road from their forested mountainside habitats, there were some vernal pools where the salamanders were congregating. These temporary pools of spring rainwater and melted snow are where certain kinds salamanders and frogs lay their eggs.
spring-peepers and wood frogs nearby the pools.
See my previous post that explains more about salamander night.
