I maintain 3 big 6-port feeders, and with peak viewing season approaching, my numbers are way down this year. 6 birds at a time is the most I've been able to count, whereas last year at this time I could easily count twice that many. Anyone else noticing reduced numbers of hummingbirds this year? Any reasoning as to why? Also, my first hummer of the year showed up a week later than normal. One would think that the previous mild winter and early bloom season would have the opposite effect. John Skaggs Powell, Knox Co.,TN
