I too live in TN, and smack dab on the migratory chart I guess. I thought I had a great deal, of about 50, but I see others have more. They usually are sited, only a few in the last of March or First of April. Then I usually see them again around June to October. I have about 11 feeders I put out, and when it is the busy time I fill them every day or every other day. Most of the feeders we put on the front covered porch, it is 50 ft long, with all of our trees and bushes, they seem to love it. We love watching them and taking photos.
