This evening I am sitting in my studio watching a half dozen or so hummingbirds drinking, or trying to drink, from two feeders with 10 “flowers”. Sometimes they come singly, sometimes as groups. There are two lighter colored birds that will not tolerate the presence of each other or any-bird else. Some perch on the tiny rail of the feeder and drink to their heart's content. Others are skeptical and use the dip-and-flee method, getting only a drop or two at a time, and probably exhausting that fuel in the next attempt, never filled.
