I have planted salvia greggii (which is a pink flowering shrub) in our front yard that the hummingbirds are attracted to. All day long, I see them feeding on the pink flowers. Once they have fed, they will often fly into the palo verde tree and perch in the green branches. They aren't particularly afraid of me or Pono, and more than once, they have flown right up to my face, as though they are telling me something urgent. Everything about the hummingbird seems urgent, with their quick movements and buzzing wings.
