Can you watch the feeders for a while to see how much traffic you are getting? If you have frequent visitors, they are draining it. We have a lot more Hummers than we did last year, and since our flowers have not done well this summer they seem to be hitting the feeders hard.

We have 7 feeders that hold about one to one and a half cups, and have to refill them every day or every other day. 6 of the feeders are clustered out back, and we have found they share a little better when they are positioned this way.

Last evening we watched about a dozen Hummers alternately fighting and sharing seats at the feeders out back. It is amazing to watch that many of them in one area.
