It took less than a second from beginning to failure. It took a jink of less than an inch for the pigeon to save its life.
On top of the water tower a peregrine is perched on a railing. It is a rare winter’s afternoon — bitterly cold, startlingly blue — and the falcon is motionless. Underneath the pigeons come and go, flying under the arched sides of the tower to shelter inside. The peregrine doesn’t stir, sitting hunched in the weak sunshine. Its grabbing, stabbing middle talon is long and clings to the rusting metal. A living gargoyle.
Familiarity breeds complacency.
A white pigeon flares in the sunlight. It drops low and slow and glides towards the tower. The peregrine knows. As the pigeon approaches, the falcon flips forward and plunges to earth like an axe. The pigeon sees and veers and is home under the tower in a split second, spared by an inch, by the flick of a white wing. The falcon swings up, drifts over, and resumes its familiar gargoyle perch on the other side of the tower.
It will fail and fail again in the space of a second, by the distance of an inch. The pigeons keep coming to the tower. The peregrine bides its time.
