I am also very concerned about my hummingbirds. I live on Hurricane Hill in WRJ. I have been feeding them for years and always have large numbers all spring and summer. I had more than the usual numbers this year . They arrived right on time on May 8th. But 2 weeks ago I saw a drastic decrease in the number of birds at my feeders. I am extremely fastidious with my feeder cleaning and regularly put out fresh nectar, that I make myself after boiling the water and adding the sugar. I always have a slight decrease every year, that I attribute to the nesting and mating period. But this seems so different. I now have a few males and females. I wish that some of the more knowledgeable birding experts would weigh in on this.....something is very different this year. I am so thankful that I at least still have a few. I would be so sad if they disappear completely.
