Didelphis aurita (Wied-Neuwied, 1826) is a marsupial common in the Atlantic Forest and Cerrado but understudied. Thus, we estimated the size of the home range and shelter preferences for three individuals (one male and two females) of D. aurita with spool-and-line and radio-tracking techniques in a forest fragment located in the transition area between the Atlantic Forest and Cerrado. The home range estimated by spool-and-line was 1.2±0.7 ha; 0.8±0.2 ha for radio-tracking and 1.8±0.5 ha for both methods together. We identified 20 different shelters, used more than once by individuals. The vine tangles were mostly used when compared with tree hollows and holes in the ground. Comparing with other studies, home range seems to be proportional to the fragment area, being larger in forest fragments surrounded by urban area than in fragments immersed in an agricultural matrix. We recommended more studies evaluating the use of space by D. aurita in different types of environments to conclude if the preference for vine tangles as shelter is a characteristic of the species or our sampling area, which has a large availability of shelters of this type.
