In the summer of 1995, an adult Crotalus viridis
(sex unknown) was observed to manipulate the vegetation near a deer mouse (Peromyscus species) nest burrow (J.
Shedding aggregations of Crotalus viridis
Evolutionary aspects of isozymes patterns, number of loci, and tissue-specific gene expression in the prairie rattlesnake, Crotalus viridis
Fourteen adult rattlesnakes were used as subjects (4 Crotalus viridis
, 3 Crotalus atrox, 3 Crotalus oreganus, 2 Crotalus helleri, 1 Crotalus horridus, and 1 Crotalus lutosus).
One of the most prevalent is the avoidance of the various species of Crotalus--which, in my neck of the woods, includes Crotalus atrox, Crotalus lepidus and Crotalus viridis
Characterization of a reovirus isolate from a rattle snake, Crotalus viridis

Female reproductive cycles of the snakes Arizona elegans and Crotalus viridis
However, other rattlesnake species may have an annual, biennial or triennial reproductive cycle in different parts of their range: Crotalus atrox (Tinkle 1962; Fitch and Pisani 19 93; Price 1998; Werler and Dixon 2000); Crotalus viridis
(Rahn 1942; Diller and Wallace 1988; Macartney and Gregory 1988).
