Mexican gartersnakes (Thamnophis eques) along the Gila River in southwestern New Mexico

.-The Mexican gartersnake (Thamnophis eques) is a federally threatened species in the United States, with exists regarding their status and natural history; thus, all observations are noteworthy. Along the Gila River in New Mexico, for example, only 2 observations of this species have been published, one in 1883 and one in 1973. Herein, I report viduals were documented in riparian habitats close to or in water, but one was observed in more arid habitats away from riparian habitats. Two individuals were found dead on paved roadways, demonstrating that mortality along roads is a threat to this limited population that generally is associated only with wetland habitats. Further surveys are warranted in the area to better understand the status and habitats used by this rare species in the region.
