I had two windows removed and one big window put in last year. And a new deck. So of course we added some bird feeders and some plants. Then I discovered that there is a huge difference in bird seeds. I'd been using a cheap seed from the dollar store or from the grocery store. I went to Lowe's and bought a bag while I was there. Now the birds are all over it. Tons of different kinds of birds. And then, this. I am sure he knew I was there because he watched me. He's been back several times.
