Hoffmeister 1941 Marmota flaviventris April 16 Along Truckee River, on highway, 4 3/4 mi. E Sparks, Washoe Co., Nev. Found an adult ♀ marmot run over on the highway. This is at the base of some "cliffs" and rock slides which come down to the roadway. I saw at least 2 more marmots running around in the rock slide, about 200 feet above the road, when I stopped to pick the dead animal off the highway. This was at about 3 p.m. and it had been snowing^ ing lightly (not enough to cover the ground). The marmots were apparently active regardless of the cold weather. The stomach of the dead animal was filled with green material (plant). The mammae were very large, indicating the ♀ was nursing young already in April.
