We have had more hummers this summer then we have ever had before. Six feeders out and everyone of them were filled with hummers most of the time. I had to bring them in at dark each night to keep the raccoons from drinking the sugar water, and when I would bring them out in the morning the hummers would be on them before I could get them hung up. However, I have not seen a hummer for three days now so I brought the feeders in, washed them and packed them away for the winter.
