I am so sad. I have had 3-5 hummers every year for about 15 years. This year, 1 male hummer showed up at the usual time for about a week, but I haven't seen him for 3 weeks.
I'm still putting out fresh nectar every few days, but they seem unvisited.
It is going to be a long lonely summer without any hummers around, but I am more worried about what happened to them. I am convinced that they tended to return here each year (because I noticed the ways that some held their feet or tails while feeding). I can't help wondering what happened to them...
