The eastern deer mouse (Peromyscus maniculatus) is a rodent native to eastern North America. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice". When formerly grouped with the western deermouse (P. sonoriensis), it was once referred to as the North American deermouse, a species that is no longer recognized. It is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland Southeastern United States. Like certain other Peromyscus species, it can be a vector and carrier of emerging infectious diseases such as hantaviruses and Lyme disease. It is closely related to Peromyscus leucopus, the white-footed mouse. Wikipedia →

Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
