I'm 85 years old and never saw a humming bird until 5 years ago when I visited a friend in Wisc. who had several feeders and there were so many hummers that I could not count them. So I put up a feeder each year and planted Bee-Balm flowers and finally saw 1 or 2 each afternoon. So far this year 7/17/23 I have only seen  a couple and one actually visited the feeder. I have a bird feeder with a camera and am thinking of adding a humming bird feeder in front to capture the ruby throat hummingbirds in the Chicago area. Is there any best mixture and style of feeder?
