What

pinyon mouse Peromyscus truei

Observer

th0th

Date

February 19, 2012

Description

Definitely Peromyscus as opposed to house mouse or harvest mice because tail is more than 1/3 length of body, and no grooves on upper incisors. Pinyon mouse as opposed to deer mouse because ears are longer than 18 mm and hind feet longer than 21 mm. This would be out of range, and slightly too small for P. californicus (which would be about 20 mm longer)
