I was photographing a Giant Galapagos Tortoise rummaging for food when a Yellow Warbler suddenly floated into my frame to check out the scene. The tiny bird contrasts in scale, color, and movement to the huge tortoise. I deliberately spot metered on the bright yellow bird, deepening the shadows around the head of the tortoise to emphasize the contrasting bird. I was able to capture considerable blur in its wings, which adds incongruous energy to an otherwise placid image. This photograph speaks of the interdependence of various creatures -- the bird is also looking for food, and may well remove bothersome insects from the body of the tortoise.
