I purchased a hummingbird feeder today. I filled it and put it out an hour ago. I just saw a little hummer feeding! That's quick. Around here they say to leave your feeders up until Halloween. In past years, I have been lucky to have 2-3 hummingbirds in the neighborhood. I know down Jack's way, southern Missouri, there will be dozens and dozens chirping and squabbling to feed at one time. So sweet.
