and the young follow the mother as soon as hatched. The males leave
the females whenever incubation has commenced, and do not join them
again until late in autumn ; indeed, they remove to different woods, where
they are more shy and wary than during the love season or in winter.
This species walks much in the manner of our Partridge. I never saw one jerk its tail as the Ruffed Grous does, nor do they burrow in the snow like that bird, but usually resort to trees to save themselves from their pursuers. They seldom move from thence at the barking of a dog, and when roused fly only to a short distance, uttering a few cluchs, which they repeat on alighting. In general, when a flock is discovered, each indi- vidual forming it may be easily caught, for so seldom do they see men in the secluded places which they inhabit, that they do not seem to be aware of the hostile propensities of the race.
Along the shores of the Bay of Fundy, the Spruce Partridge is much more abundant than the Ruffed Grous, which indeed gradually becomes scarcer the farther north we proceed, and is unknown in Labrador, where it is replaced by the Willow Grous, and two other species. The females of the Canada Grous differ materially in their colouring in different lati- tudes. In Maine, for instance, they are more richly coloured than in Labrador, where I observed that all the individuals procured by me were of a much greyer hue than those shot near Dennisville. The like difference is perhaps still more remarkable in the Ruffed Grous, which are so very grey and uniformly coloured in the Northern and Eastern States, as to induce almost every person to consider them as of a species distinct from those found in Kentucky, or any of the southern mountain- ous districts of the Union. % have in my possession skins of both species procured a thousand miles apart, that present these remarkable differences in the general hue of their plumage.
All the species of this genus indicate the approach of rainy weather or a snow storm, with far more precision than the best barometer; for on the afternoon previous to such weather, they all resort to their roosting places earlier by several hours than they do during a continuation of fine weather. I have seen groups of Grous flying up to their roosts at mid-day, or as soon as the weather felt heavy, and have observed that it generally rained in the course of that afternoon. When, on the contrary, the same flock would remain busily engaged in search of food until sunset, I found the night and the following morning fresh and clear. Indeed, I believe that this kind of foresight exists in the whole tribe of GaUinaceoiis birds.
