Detail of a colorful male in flight. Actually, he is kiting. On a much smaller scale than the kite (and the kestrel): much lower, after smaller prey: insects, not voles. And the bluebird does not stay so heartbreakingly still for so long, suspended in the moving air, a stationary anchor in the midst of change: fooling a vole into considering it a given fact of nature, not a watchful predator ready to pounce.
