Summer food habits of the Patagonian opossum, Lestodelphys halli (Thomas, 1921), in southern arid Patagonian shrub-steppes
The summer diet of the Patagonian opossum Lestodelphys halli was studied in southern Argentinean Patagonia. Faeces of opossums captured alive and stomach contents from dead animals were collected and analyzed. A wide variety of invertebrates (87.2% frequency of occurrence) followed by birds and rept...
