Notes on the ecology of the opossum in Maryland Notes on the ecology of the opossum in Maryland
Livetrapping of opossums at the Patuxent Research Refuge in Maryland over an 8-year period resulted in the capture of 224 opossums, with 541 trap records. The maximum recorded trap life was 29 months, and the greatest estimated age was 36 months. Opossums did not enter traps readily, and the average period between consecutive captures was 31 days. Trap records indicated that opossums...
