Hummingbird skeleton

Several years ago a hummingbird flew into our front window and died. My son and I found the body on our front stoop. We had recently seen, I think, the living decay exhibit at the Exploratorium, so I told my son let's just put the body in the garden and see what happens. In a day or so, ants had created a small dirt mound beneath the hummingbird as they excavated a tunnel that ended just beneath the bird. There they scavenged bits of the bird and carried the bits away bit by bit. The eyes were already gone when we first checked. Within 3 days only a clean white skeleton remained and the ants were gone.
