Opossums
If you find a medium-sized mammal rummaging through your outdoor pet food bowls or knocking over garbage cans after dark, you are likely looking at an opossum, the only native marsupial in North America north of Mexico. What unites these creatures in our library index is their unique combination of primitive marsupial traits, a long pointed face, naked ears, and a scaly prehensile tail that allows them to climb trees, scale deck lattice, and forage around suburban properties without ever building complex underground burrows.
Telling an opossum apart from the other wildlife that visits your yard comes down to spotting a few clear physical giveaways rather than guessing based on nighttime noises. Raccoons wear a bold black facial mask and bushy ringed tails, while striped skunks carry wide white back stripes and heavy digging claws. An opossum lacks these markings entirely, showing a greyish-white coat and a naked tail. If you happen to check the mud near your porch steps after a rainy night, the tracks settle the question immediately because the hind foot features a widely separated, clawless thumb-like toe that points sideways, completely unlike the prints left by local rodents, cats, or raccoons.
