Reithrodontomys sumichrasti

Sumichrast’s Harvest Mouse

Order: Rodentia
Family: Cricetidae


Conservation Status: Least Concern.

Sumichrast's Harvest Mouse has short, sparse whiskers and a comparatively short tail for a harvest mouse: its tail is only about as long as its head and body. It favors open habitat such as forest edges, brush, and coniferous forests. It is mainly terrestrial, and will sometimes nest on the ground; one nest was found in a coffee field, under a log. Most other harvest mice build their nests above the ground, in vines or other vegetation. It has a fairly wide range, occurring in cold, wet mountains in parts of Mexico, Nicaragua, Costa Rica, and Panama. Its litters range in size from 3-5.

Range: Head and Body: 64-93 mm; Tail: 65-98 mm

Range: 8-13 g
