We have had visitors to our bird feeder! These purple finches have been the only birds we have spotted using our feeder. We have also seen cardinals, mockingbirds, and bluejays in our yard: these are common to our area. A new one we haven't noticed before is the loggerhead shrike!
eNature.com is a wonderful site to explore. It has a park finder for your area and all kinds of nature information you can use for self-study or use as a resource in your homeschool.
