Harvest Mice are small, rather dull-colored creatures which 

 are seldom seen. They are denizens of grassy localities and 

 are more or less restricted to the warmer zones, the genus 

 reaching its highest development in Central America. The 

 best field character for separating Harvest Mice from other 

 small Mice is the presence of the grooved upper incisors. 



These Mice build grass nests which are placed either on 

 the ground or in low vegetation; sometimes a deserted bird 

 nest is used. Harvest Mice do not hibernate and are active 

 both day and night. They are not as abundant as most other 

 Mice, and only rarely do damage to crops. 



There are "probably several litters of young born annually, 

 from two to four in a litter.
