I've had them buzzing all over mine since I started this thread, but suddenly they disappeared a couple of days ago. Not a one in sight. I went out and checked, and the thing was 100% empty and dry. I don't remember it emptying out so quickly last year. So I immediately cleaned it out, replaced the nectar, and hung it out there again, and now two days later, still not a single hummingbird. I guess they figured it had only so much nectar, and now they need to move on to someplace else. Hopefully, they will soon rediscover it.
