Edward Step, Animal Life of the British Isles
“ Brown Rats are an insufferable nuisance. There is no courtesy or kindness in the nature of the Rat; no nesting bird is safe from his attacks, unless her home is beyond his reach in some cleft of a rock that he cannot scale or in some fork of a tree that he cannot climb. He is a cannibal—even the young and the sick of his own kind become the victims of his rapacious hunger—and he will eat almost anything, living or dead, from the refuse in a garbage heap to the dainty egg of a willow-wren in the tiny, domed nest amid the briars at the margin of the river. ”
