Selborne, Mark 30, 1768.
Dear Sir,
Some intelligent country people have a notion that we have, in these parts, a species of the genus mustelinum, besides the weasel, stoat, ferret, and polecat; a little reddish beast, not much bigger than a field mouse, but much longer, which they call a cane. This piece of intelligence can be little depended on; but farther inquiry may be made.
A gentleman in this neighbourhood had two milk-white rooks in one nest. A booby of a carter, finding them before they were able to fly, threw them down and destroyed them, to the regret of the owner, who would have been glad to have preserved such a curiosity in his rookery. I saw the birds myself nailed against the end of a barn, and was surprised to find that their bills, legs, feet, and claws were milk-white.
A shepherd saw, as he thought, some white larks on a down above my house this winter: were not these the emberiza nivalis, the snow-flake of the Brat. Zool.? No doubt they were.
A few years ago I saw a cock bullfinch in a cage, which had been caught in the fields after it had come to its full colours. In about a year it began to look dingy; and, blackening every succeeding year, it became coal-black at the end of four. Its chief food was hemp- seed. Such influence has food on the colour of animals! The pied and mottled colours of domesticated animals are supposed to be owing to high, various, and unusual food.
