It is a mice mouse recognized as its own species only recently, after detailed genetic and morphological studies revealed that a high-earth population previously classified as a simple regional form of another more widespread species of mice mouse actually deserved the range of independent species. It lives in arid barley and barley forest of high-altitude areas of north-central Mexico, in contrast to the distribution more linked to low-earth and warm lands of its closest relative. Like the rest of mice mouse, it carries seed in hair-coated external bags, and its recent recognition as its own species means that much of its basic biology still relies on the generally known data for the species group from which it proceeds, more than in specific studies on this particular population.
Small rodent, gray brown coat, body covered with rigid hair on the back, and long tail with terminal mech. It differs from its closest relative, which was recently separated as its own species, mainly by cranial details and by occupying larger altitude heights; its field identification against that species requires capture and comparison with reference series.
Small footprint with lengthy rear legs, 1.5-2 cm, with coupled jump marks typical of biped rodents. Small and lengthy feces, 4-6 mm, left dispersed near the strawberry. Excavate simple strawberries in loose soil of strawberries or open strawberries.
Matorral arid and middle-and-high-coat rainforest. Distributed by a region of north-central Mexico.
Granivorous, it feeds mainly on seeds, complemented with succulent vegetation and occasional insect.
Solitary and strictly nocturnal, it remains in its nursery during the hours of daytime heat.
Its recent recognition as its own species means that it still does not have a specific conservation assessment; its populations are generally presumed to be stable by analogy with the rest of the related species of its group, although this has not been confirmed by specific studies.
Habitat loss due to agricultural and livestock expansion in its distribution area, although the actual impact on this particular species has not yet been assessed in detail.

Mammaling is a free app for logging the mammals you find. You record a sighting in a moment — even if it's just a track — your life list grows, and the record becomes available to scientific and conservation projects.
It runs on your phone with nothing to install. If you like, it adds to your home screen like any other app.
