Harvest mice reside in a large variety of habitats, from hedgerows to railway banks. Harvest mice seem to have an affinity for all types of cereal heads, except for maize (Zea mays). Harvest mice typically like using monocotyledons for their nest-building, especially the common reed (Phragmites australis) and Siberian iris (Iris sibirica). [7]
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals.

The fulvous harvest mouse is nocturnal. In Arkansas, animals began to deposit fat in their tissues in November and this peaks in January and then the fat reserves are steadily used up by April. Other adaptations to winter include a lengthening of the animal's hair and a possible daily reduction of its body temperature during sleep in the ...

The distinction is not absolute, because crepuscular animals may also be active on a bright moonlit night or on a dull day. Some animals casually described as nocturnal are in fact crepuscular. [2] Special classes of crepuscular behaviour include matutinal, or "matinal", animals active only in the dawn, and vespertine, only in the dusk.
Similar species are the plains harvest mouse (Reithrodontomys montanus) and the fulvous harvest mouse (R. fulvescens), which has a longer tail.The species co-occurs with the similar western harvest mouse (R. megalotis), which tends to have dorsal fur that is more gray than R. raviventris and with ventral fur that is white to grayish; and the house mouse (Mus musculus), which is gray, has a ...
Micromys is a genus of small rodents in the subfamily Murinae.The genus contains two living species: the widespread Eurasian harvest mouse (Micromys minutus) of much of Europe and Asia; and the more restricted Indochinese harvest mouse (Micromys erythrotis) of Vietnam, southern China, and perhaps nearby regions.
