“What's evil for the hawk is the mouse because, you know, the mouse is quick and gets away but I did this one realization every scientist goes through at one point… if you gave the hawk power, the power of God, the first thing the hawk might do is to slow down the mouse. But then the hawk would lose it's speed. And then if you slow the mouse all the way down, so it can just barely move, the hawk would lose its flight. So that in a weird way the tension between those two say natural enemies is what gives birth to their beauty. So I definitely feel that the tension we have right now within the human community in particular — that those are ultimately going to be resolved with a deeper harmony and a deeper appreciation for one another.”

The facts and fancies of Mr. Darwin (1862)
Context: Though the large runt pigeon, with its massive beak and its huge feet, differs from its blue and barred progenitor the rock, it is a pigeon still. Though the slender Italian greyhound has a strange contrast with the short-legged bull-dog, they are both dogs in their teeth and in their skull. The mouse, even, has not been transmuted into the cat, nor the hen into the turkey, nor the duck into the goose, nor the hawk into the eagle, and still less the monkey into the man.

The Sports and Pastimes of the People of England (1801), Rank of hunting birds

Queen Victoria, concerned about the sparrows that had nested in the roof of the partly finished Crystal Palace, asked Wellington's advice as to how to get rid of them. Wellington’s reply was succinct and to the point, Sparrow-hawks, Ma'am. He was right, by the time the Crystal Palace was opened by the Queen in 1851, they had all gone!

The Gentle Falcon (1957)
Context: I think hawking is the nearest thing to flying in this world. There you sit high up and poised light as air, the horse swift beneath you. You unhood your bird, let the jesses go and watch your falcon, its bells a-jingle, like some wild spirit take the air … and your own spirit goes with it. <!-- p. 51
