“The female alone understands the task of incubation and the care of the young. Once, however, when I came upon a young brood, the agonized cry of the distressed mother attracted a fine cock bird. He raised all his feathers and, with ruffs and tail spread, strutted up to within a rod of my position, seemingly almost as much concerned as the female, but not coming quite so near. The hen sometimes struts forward toward the intruder in a similar manner, when surprised while with her young. She can raise her ruffs and strut exactly like the cock. “The Grouse has so many enemies that it seems remarkable how it can escape them, nesting as it does on the ground. Instances are on record, however, where birds, that probably have been much persecuted, have learned to deposit their eggs in old nests of Hawks or Crows, in tall trees. Whenever the mother bird leaves the nest, the eggs are easily seen, and, while she sits, it would seem impossible for her whereabouts to remain a secret to the keen-scented prowlers of the woods. But her colours blend so perfectly with those of the dead leaves on the forest floor, and she sits so closely, and remains so motionless among the shadows, that she escapes the sharp-eyed Hawk. She gives out so little scent that the dog, skunk, or fox passes quite near, unnoticing. “The Grouse does not naturally fear man; more than once, in the wilderness of the northwest, a single bird has walked up to within a few feet of me. They will sit on limbs just above one’s head, almost within reach, and regard one curiously, but without much alarm. Usually, in Massachusetts, when a human being comes near the nest, the mother bird whirs loudly away. She has well learned the fear of man; but, in a place where no shooting was permitted, a large gang of men were cutting under-brush, while a Partridge, sitting there, remained quietly on her nest as the men worked noisily all about her. Another bird, that nested beside a woods road, along which I walked daily, at first would fly before I had come within a rod of her; but later she became confiding enough to sit on her nest while six persons passed close beside her. Evidently the bird’s facility in concealing her nest consists in sitting close and keeping her eggs well covered. Her apparent faith in her invisibility is overcome only by her fear of man or her dread of the fox. When the fox is seen approaching directly toward her, she bristles up and flies at him, in the attempt to frighten him with the sudden roar of her wings and the impetuosity of her attack; but Reynard, although at first taken aback, cannot always be deceived by such tricks; and the poor bird, in her anxiety to defend her nest, only betrays its whereabouts. Probably, however, the fox rarely finds
