I love these little critters. We have set out an extra feeder, and planted plants that's supposed to attract them, hoping to bring more. Last year we started with two (1 male and 1 female), and towards the end of the season, we had four. I think the other two that showed up were the babies of the first two, that had fledged, and was learning to feed themselves. I say this because sometimes one would land on the feeder's rest, and just sit there, like it was wondering "what do I do now?"
