Perote Deer Mouse

Peromyscus bullatus

Declining

Overview

The Perote mouse, or Perote deermouse, is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a group of New World mice often referred to as "deermice". It is found only in Mexico.

Peromyscus bullatus faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range. The species' restriction to a small geographic area makes it particularly vulnerable to localized environmental changes and human activities. Mining operations and infrastructure development pose additional pressures on the remaining suitable habitat patches.
