Living Like Weasels
by Annie Dillard

A weasel is wild. Who knows what he thinks? He sleeps in his underground den, his tail draped over his nose. Sometimes he lives in his den for two days without leaving. Outside, he stalks rabbits, mice, muskrats, and birds, killing more bodies than he can eat warm, and often dragging the carcasses home. Obedient to instinct, he bites his prey at the neck, either splitting the jugular vein at the throat or crunching the brain at the base of the skull, and he does not let go. One naturalist refused to kill a weasel who was socketed into his hand deeply as a rattlesnake. The man could in no way pry the tiny weasel off and he had to walk half a mile to water, the weasel dangling from his palm, and soak him off like a stubborn label.

And once, says Ernest Thompson Seton--once, a man shot an eagle out of the sky. He examined the eagle and found the dry skull of a weasel fixed by the jaws to his throat. The supposition is that the eagle had pounced on the weasel and the weasel swiveled and bit as instinct taught him, tooth to neck, and nearly won. I would like to have seen that eagle from the air a few weeks or months before he was shot: was the whole weasel still attached to his feathered throat, a fur pendant? Or did the eagle eat what he could reach, gutting the living weasel with his talons before his breast, bending his beak, cleaning the beautiful airborne bones?

I have been reading about weasels because I saw one last week. I startled a weasel who startled me, and we exchanged a long glance.

Twenty minutes from my house, through the woods by the quarry and across the highway, is Hollins Pond, a remarkable piece of shallowness, where I like to go at sunset and sit on a tree trunk. Hollins Pond is also called Murray's Pond; it covers two acres of bottomland near Tinker Creek with six inches of water and six thousand lily pads. In winter, brown-and-white steers stand in the middle of it, merely dampening their hooves; from the distant shore they look like miracle itself, complete with miracle's nonchalance. Now, in summer, the steers are gone. The water lilies have blossomed and spread to a green horizontal plane that is terra firma to plodding blackbirds, and tremulous ceiling to black leeches, crayfish, and carp.
