PHENOLOGY FRIDAY - PALISADE PORCH POSSUM EDITION
Opossums (or possums, as they are commonly called) have lived in southern Minnesota for about a century. With the climate warming, they have been expanding their territory northward and are likely to become more common in the coming years. This week there was a sighting close to Long Lake Conservation Center, near Palisade. Here's what you need to know about these interesting animals and how they might fit into our ecosystem. Opossums eat just about anything, including fruit, eggs and young birds, worms, snakes, insects, and even garbage and carrion. This one was eating seeds under a bird feeder. Their predators include dogs, bobcats, coyotes, foxes, hawks, and owls. Because they also like to eat roadkill, many possums are killed by vehicles as they scavenge for food on roadways. They are more active in the evening. When threatened, opossums may click their teeth, growl, screech, or lie still and secrete a foul-smelling scent. This is commonly known as “playing dead” or “playing possum.” The Palisade possum is up in garage rafters living in a den of insulation and making a big old mess on the car below. The resident (and the UPS delivery driver) would like the possum to find another home. Especially when it was discovered that possum mating season begins in January and litters are six to 20 young!
