"So much of animal life is the recognition of pattern, the shapes of hunter and hunted. To the casual eye the forest is, well, just forest; to the eye of the dove it is so much unimportant fuzzy green background to the hawk which you did not notice on the branch of a tree. To the tiny dot of the hunting buzzard in the heights, the whole panorama of the world is just a fog compared to the scurrying prey in the grass. (p. 62)"
