I'm new to the forum and in reading some of the older threads saw this one. You are so lucky to have not only so many but such a wide variety.
Here in North Carolina, we have only the Ruby Throated. For the past few years we had only two show up each spring but this year we are seeing many more. We have to refill the feeder about every two days. I love to stand near the feeder and watch them up close and personal. They seem to have no fear and will fly very close to my face.
We have found they like the clear water better also.
