I started having the guy who mows my grass leave one small back section of the property untouched so I could hopefully attract more native birds and insects. It's a part of my yard that I don't go into and neither do my dogs, so I figured it was as good a spot as any for the experiment. After a couple months, it worked to bring in birds. I have a pair of bluejays with a nest in my tree. I hadn't seen bluejays anywhere around before now, and I've lived in my house for 3 years.
