WHIP-POOR-WILL.

I have known both birds from my early youth, I have seldom seen a farmer or even a boy in the United States, who did not know the difference between them.

It is a remarkable fact that even the largest moths on which the Whip-poor-will feeds, are always swallowed tail foremost, and when swallowed, the wings and legs are found closely laid together, and as if partially glued by the saliva or gastric juice of the bird. The act of deglutition must be greatly aided by the long bristly feathers of the upper mandible, as these no doubt force the wings of the insects close together, before they enter the mouth.

I have represented a male and two females, as well as some of the insects on which they feed. The former are placed on a branch of Red Oak, that tree being abundant on the skirts of the Kentucky Barrens, where the Whip-poor-will is most plentiful.
