California Mouse

Peromyscus californicus


I always take a photo of this den when I walk by in hopes of seeing what lives there. Today a mouse was in the shot! "The California mouse has very large ears, and a tail that is longer than the head and body combined. Including the tail, which is about 117 to 156 mm long, the mouse ranges in length from 220 to 285 mm. The coat is overall brown, mixed with black hairs. This dorsal colour shades to a creamy-white belly colour. The manus and feet are white " - Wikipedia


Rocky area of riparian, Oak Forest. This is the largest Deer Mouse species in the U.S.


"While most rodents are polygamous, the California mouse pair bonds, making it a model organism for researchers studying the genetics and neurobiology of partner fidelity.P. californicus is mostly active at night. The main predators of the California mouse are weasels and barn owls." - Wikipedia
