Common Critters - Backyard Mammals - Part 1

Squirrels are very common backyard critters with little fear of humans. They are attracted to our yards by bird feeders, compost piles, and trees, particularly oak trees. Depending on where you live in the U.S. you may see different kinds of squirrel visitors. In the Midwest we are likely to see Eastern Fox Squirrels, Eastern Gray Squirrels, and Red Squirrels. Both Northern and Southern Flying Squirrels can be found in the Midwest. Squirrels particularly enjoy eating acorns, sunflower seeds, peanuts, and cracked corn. If you have oak trees like many people do, whether they be White Oak, Pin Oak, Black Oak, or Red Oak, you will certainly end up with squirrels gathering acorns and burying them in your yard. Of course, squirrels can also get themselves into trouble by foraging in vegetable gardens and climbing bird feeders, and because they are more nimble and dexterous than rabbits keeping them out of trouble is a big ask. In the case of feeders, you may want to make sure to use baffles and be very aware of your feeder's placement. In the case of vegetable gardens, it's worth considering something like bird netting to put over your produce. More on Squirrels from UW Extension

Chipmunks are squirrel-like rodents who spend much of their time on the ground. Eastern Chipmunks and Least Chipmunks are common in the Midwest and can be seen feeding under bird feeders gathering any seeds dropped by our feathered friends. Because they burrow, some people find them to be a nuisance. We've often been entertained by their high energy antics, we've even witnessed them scamper up the bird feeder pole and devour some safflower seeds. Chipmunks will also try to compete with squirrels for morsels at bird feeders but will find themselves overpowered by their larger cousins. Chipmunks are capable climbers and will also eat berries from shrubs and small trees.

Ground Squirrels are very similar to chipmunks and can often be seen along the roadside next to farmers' fields. You may see them dart across the road, they usually appear longer and thinner than chipmunks and don't have the solid white stripes which are characteristic of chipmunks. The 13-Lined Ground Squirrel and the Franklin's Ground Squirrel both call Wisconsin home. We've had the 13-Lined Ground Squirrel visit our bird feeders and have witnessed short skirmishes between them and chipmunks competing over seeds. The Franklin's Ground Squirrel lived in the tallgrass prairie but as much of its habitat has been destroyed; it's now a species of Special Concern. If you've decided that the burrowing chipmunks and ground squirrels are a problem, before setting traps make sure you've correctly identified the species; also consider consulting with your local DNR or animal control.

Cottontail Rabbits are happy to make your lawn or garden their home. They enjoy eating grass, most flowers, vegetables, berries, clover, pretty much anything. They even chewed branches off of my Red Chokeberry and my Serviceberry shrubs. Fencing or raised garden beds can be an effective means to be prevent rabbits from eating what you've planted. We struggled for much of last Spring and Summer with the rabbits eating the Purple Coneflowers, Blue Lupines, and False Indigo. Eventually we put up plastic fencing around some of the plants, and this year we plan to fence off the whole wildflower garden until the plants have a chance to grow. We also purchased a beagle midway through the Summer, and we think she'll be an effective rabbit deterrent as well.
