The American Museum Journal Vol. IV. OCTOBER, 1904.

The Ruffed Grouse, Bob-white and Woodcock being local species, they have been for some time represented in our group collections, but with the funds now available it is proposed to add the game birds of other parts of the country. Three groups of the proposed series have already been placed upon exhibition, the California Valley and Mountain Partridges, or "Quail," (Lophortyx californicus and Oreortyx pictus plumi- ferus), and the Sierra Dusky or Blue Grouse. In each instance a pair of adult birds is shown with their nest, young and a photo- graph of the nesting site. The young in the group of Valley Partridge, or " Valley Quail," as it is commonly called in California, are less than a day old, but their well-grown, downy plumage illustrates very well the high degree of development attained by the young of all gallinaceous birds before hatching. The young in the Mountain Partridge, or "Mountain Quail," group are probably a week older, but already have acquired their second plumage and with it the power of flight. The young of the Grouse are in a corresponding stage of plumage. As to color it will be observed that the plumage of the young of all three species is of dull neutral tints which render the chicks inconspicuous through a more or less close resemblance to the prevailing tone of their surroundings. The female Grouse is also protectively colored and differs strikingly in plumage from her 71
