Eutamias townsendii July 8 Brooks Meadow, 4300 ft, 9 mi. ENE Mt Hood, Wood R.Co., Oregon that of a nearly adult animal. The animal had eaten only a small amount when a second Eutamius Townsendii appeared, and attempted, it appeared, to copulate with the first. The one eating immediately and unhesitatingly dropped the carcass, and ran slowly off through the underbrush with the second chipmunk following. I remained a few minutes & no chipmunks returned to the carcass which no longer was lodged in the bark of the tree but lay now at the base. I was impressed that the first chipmunk should so immediately return to the Zapus body after being frightened away by a human passer-by, yet unhesitatingly have it for an apparent sexual reaction or behavior. Set out 2 rat traps baited with English walnut where I had seen some E. Townsendii and re-visited traps within 1 hour and found I had 2 E. townsendii in traps. July 12 Twin Buttes, 4300 ft, 2 1/2 mi. SW Steamboat Mts., Skamania Co., Wash. Caught one specimen in traps set out during the day. This species is not as numerous here as in similar areas which have not been burned over as recently as this.
