ulDeBenedetti 1961 Thamnophis sirtalis 19 Aug Hashell Ranch, 10 mi. S. Marysville, Yuba Co., Calif. (C.A.S. Leopold Ranch). 3 snakes of this species were collected active about 6-6:30 P.M. near a large cattail-tule marsh. Two snakes were in damp (water on ground) situations with low vegetation and the third was on a dry spot about 10-12 feet from water, also with low vegetation. The first was in a small, 12 inch wide, 6-7 inch deep water drain bordered by grass and other low plants about 6-7 inches high. The water was cool, and moving quite fast. The second was in an area with open dry clumps of grass spaced at about 1-1½ foot intervals near the marsh. The snake was active when found, and did not go towards water. The third, a juvenile, was found in a grassy area, very rough ground, with the lower parts flooded. The snake crawled actively, and stayed near the edge of the closely placed grass tufts. I attempted to bite when collected, while the other two were applying their musk glands liberally on their captor. Bullhogs, (R. catesbiana) are fairly common here, and may form a good part of the snakes diet. 20 Aug. Caught one more in very wet, grassy area by large cattail swail. Grass grew about 6-7" high, fairly dense. Snake very active, but did not Bite.
