Where are the hummers?!

About a week ago, I was watching the birds flock to my feeder. I was distracted by all the other birds, so for ONCE I was not thinking about hummingbirds. Then, all of the sudden, a tiny blur of green darts into the chaos. I was startled, so it took me a second to comprehend what it was. Then it stopped for a few short seconds, and hovered. I saw it’s red throat. Oh my gosh! I thought. It’s a hummingbird! He dipped his bill into the feeder for about 2 seconds, then quickly flew away. I haven’t seen any since. Hummers are my favorite bird, so knowing they’re in the area and then not seeing anymore is frustrating! Has anyone else seen any in Kentucky or have any tips on attracting them? Please help me! I’m dying here! 🙏🏼😩
