I find it difficult enough to maintain one feeder, but I just bumped up to two again, cleansing and refilling them this morning. I relocated one shepherd's hook closer to the other (spacing 15'), just so that I could get it into the shade, because their bizarre behaviors have finally interested me enough for photographing. This lady has both of you beat. She evidentally has a hummingbird fetish and even hand feeds the little critters. I had never heard of such a thing. Personally, I think it's best for the little hummers that they obtain their nectar from the tree sap and flowers, and I intend to have many more for them next spring. At this point, they are loving the petunias, cala lillies, day lillies, bee balm, hollyhocks and zinnias, and maybe even the gladiolus and cannas lillies... unsure. One of my teenage male bluebirds just landed about 20' away, and he has become quite big.
