Osgood's Mouse is a very close relative of the pinyon Mouse, but is larger, and its tail is longer than the head and body. Osgood's Mouse lives in the mountains of southern New Mexico and throughout mountainous central Mexico. It lives in a wide variety of vegetation, but there are always rocks in its habitat where it can shelter, hide, and den. It is an expert climber, comfortable negotiating cracks and fissures in rocks.
