Robert Barnwell Roosevelt,
The Game-Birds of the Coasts and Lakes of the Northern States of America
“ Every tribe of birds has its allotted part to play; and if destroyed, not only will its pleasant songs and{13} bright feathers, gleaming amid the green leaves, be missed, but some species of bug or insect, some disgusting caterpillar or injurious fly, will escape well merited destruction, and increasingly visit upon man the punishment of his cruelty and folly.The beautiful blue-birds, the numerous woodpeckers, the tiny wrens, the graceful swallows and noisy martins, are sacred to the sportsman, and constitute one great division of the creatures that he desires to protect. ”
