The Pinnated Grous forms its nest, according to the latitude of the
place, between the beginning of April and the 25th of May. In Kentucky
I have found it finished and containing a few eggs at the period tirst
mentioned, but I think, taking the differences of seasons into considera-
tion, the average period may be about the first of May. The nest although
carelessly formed of dry leaves and grasses, interwoven in a tolerably neat
manner, is always carefully placed amidst the tall grass of some large
tuft, in the open ground of the Prairies, or at the foot of a small bush in
the barren lands. The eggs are from eight to twelve, seldom more, and
are larger than those of the Tetrao umbellus, although nearly of the same
colour. The female sits upon them eighteen or nineteen days, and the moment the young have fairly disengaged themselves, leads them away from the nest, when the male ceases to be seen with her. As soon as autumn is fairly in, the different families associate together, and at the approach of winter I have seen packs composed of many hundred individuals.
When surprised, the young squat in the grass or weeds, so that it is almost impossible to find any of them. Once, while crossing a part of the barrens on my way homewards, my horse almost placed his foot on a covey that was in the path. I observed them, and instantly leaped to the ground; but notwithstanding all my endeavours, the cunning mother saved them by a single cluck. The little fellows rose on the wing for only a few yards, spread themselves all round, and kept so close and quiet, that, although I spent much time in search for them, I could not discover one. I was much amused, however, by the arts the mother employed to induce me to leave the spot where they lay concealed, when perhaps I was actually treading on some of them.
This species never raises more than one brood in the season, unless the eggs have been destroyed, in which case the female immediately calls for her mate, and produces a second set of eggs, generally much smaller in number than the first. About the 1st of August, the young are as large as our little American Partridge, and are then most excellent eating. They do not acquire much strength of wing until the middle of October, and after that period they become daily more difficult to be approached. Their enemies are at this season very numerous, but the principal are the Polecat, the Racoon, the Weasel, the Wild Cat, and various Hawks.
