Yes, we have a feeder hanging on the outside edge of our patio. They are such fun to watch! We had a few stay all winter and now they are coming in multiples. The larger ones chase the smaller ones away so sometimes it is quite an airshow. My recipe for syrup is 1/2 cup sugar to two cups water. I put the sugar in first then fill up to the 2 cup mark and microwave to boil so the sugar dissolves, then I let it cool. I wash out the feeder and then refill.
