Vol. XXV, pp. 157-162 December 4, 1912 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON NOTES ON THE MAMMALS OF MT. GREYLOCK, MASSACHUSETTS. BY MANTON COPELAND. Bowdoin College. In company with Mr. Julius Rockwell of Taunton, Mass., I -pent from August 27 to September 4, 1911, on Mt. Greylock, Mass., trapping small mammals. Some of the species captured proved to be of special interest, a fact which induced me to publish the following notes, briefly recording the results of our collecting, and presenting available data from other sources on the present mammalian life of the mountain. Mt. Greylock, rising 3505 feet above the sea, is the highest peak in Massachusetts. Its fauna! position is so clearly defined by Messrs. W. Faxon and R. Hoffmann in their "Birds of Berkshire County," I can not do better than quote from these authors. "Altitude has as marked an influence on the flora and fauna as latitude. It is this fact that gives Greylock its great interest in the eyes of naturalists. Rising as it does far above the surrounding country, it has the character of an island of northern vegetation — a bit of the Green Mountain thrust to the southward, just as the low, sterile plains of the southern Berkshire towns present the characteristics of Connecticut fields pushed northward. Greylock is clothed to the very summit with fairly tall trees, so that it lacks the Alpine aspect of extremely lofty mountain tops. Nevertheless, there has been found on the top of Greylock, on several occasions, a bird whose normal habitat is the edge of the tree line of the loftier northern moun-tains. This bird is the Bicknell's Thrush, found on Slide Mountain in the Catskills, and some of the higher peaks of the Adirondaeks, the Green Mountains of Vermont, and the White 30— 1 j kuc. Biol. Soc.
