That hummingbirds eat enough insects to make up 40 percent of their diet, I already knew. Every creature needs protein, especially those with hearts that beat a thousand times a minute. But I never seen a humming bird in its active role as a predator.
One of the Ruby-throated hummingbirds was hovering at our feeder, sipping the sugar water, when the tiny insect leisurely floated by. The bird rose and hovered, watched the whitefly a moment as it moved away, then zipped over and snatched it from the air.
As Yogi Berra is supposed to have said, “You can observe a lot by just watching.”
