A wide range of mammals can be spotted on the Refuge. Their behavior and visibility changes with the seasons because some species hibernate in winter or remain out of sight in tunnels under the snow. However, many can be seen with their young in the spring and summer.
Reptiles usually live on drier sites while amphibians live in water and on land. Both hibernate in winter and are usually seen from spring through fall. Most are small reclusive animals not highly visible to the refuge visitor. Snakes can sometimes be seen crossing roadways, lizards frequent shrub uplands, turtles can be seen sunbathing in waterways, and frogs can be seen scurrying back to the water when they are disturbed.
A vast array of fascinating insects can be found flying, crawling or swimming all over Modoc NWR. Watch for dragonflies ‘hawking' over ponds looking for prey, butterflies 'nectaring' on flowers, and beetles and spiders scurrying across the ground.
