If it becomes necessary to protect their young, most birds seem to lose all fear. When surprised with her brood of chicks, the ruffed grouse and nearly all ground-dwelling birds will feign injury and flutter a few feet in front of the intruder, seemingly in great agony. The cries and actions are intended to lure you from the young. During the interval that you are watching or chasing her, the chicks have fairly melted into the earth.

The stickleback is a small fish that inhabits the brackish waters from Cape Ann to New Jersey. Mr. Hornaday says that the abdomen of the male has been provided with a gland filled with a clear secretion which coagulates into threads when it comes in contact with the water. By means of this, a hood-like nest large enough for the female to enter is fastened to the vegetation at the bottom of the sea, and the eggs are deposited in the nest.

Birds seem to have a common language, so far, at least, as conveying a warning of danger is concerned. The appearance of a hawk, or an owl, will cause a catbird, robin, vireo, or song sparrow to give a warning note which is at once heeded by every feathered neighbor within hearing. Instantly all is quiet until danger has passed.
