Starvation didn't concern the watchbirds, since it was an act of omission.

Their interest lay only in acts of commission.

Hunters sat home, glaring at the silver dots in the sky, longing to shoot them down. But for the most part, they didn't try. The watchbirds were quick to sense the murder intent and to punish it.

Fishing boats swung idle at their moorings in San Pedro and Gloucester. Fish were living organisms.

Farmers cursed and spat and died, trying to harvest the crop. Grain was alive and thus worthy of protection. Potatoes were as important to the watchbird as any other living organism. The death of a blade of grass was equal to the assassination of a President—

To the watchbirds.

And, of course, certain machines were living. This followed, since the watchbirds were machines and living.

God help you if you maltreated your radio. Turning it off meant killing it. Obviously—its voice was silenced, the red glow of its tubes faded, it grew cold.

The watchbirds tried to guard their other charges. Wolves were slaughtered, trying to kill rabbits. Rabbits were electrocuted, trying to eat vegetables. Creepers were burned out in the act of strangling trees.

A butterfly was executed, caught in the act of outraging a rose.
