A male Eastern Massasauga rattlesnake named Gordo met his demise on Matchett Road last summer, but his genetic legacy lives on. Gordo successfully bred before his death, and now seven baby rattlesnakes, his offspring, are being nurtured for future release into the local habitat. Jonathan Choquette, a biologist leading the Ojibway Prairie Reptile Recovery program, expressed enthusiasm for the symbolic continuation of Gordo’s lineage, highlighting the unique Ojibway genetics carried by the newborn snakes.
The Eastern Massasauga rattlesnakes, native to Windsor-Essex, are on the verge of extinction in the area, with estimates suggesting their numbers could be fewer than 10. As the only venomous snake species in Ontario, they are critically endangered statewide. These snakes are typically unobtrusive but may rattle or retreat when threatened, only resorting to biting as a last defense.
Gordo, a significant male specimen introduced to revitalize the local population at the Ojibway Prairie Complex, was closely monitored by Choquette’s team. Despite being raised at Toronto Zoo, Gordo’s lineage can be traced back to rescued Eastern Massasauga rattlesnakes from LaSalle over 25 years ago. Unfortunately, Gordo was found dead on Matchett Road in September 2025, likely a victim of a vehicular accident, identified by his implanted electronic transmitter.
According to Choquette, the local Eastern Massasauga population in Windsor-Essex faces the threat of local disappearance unless conservation efforts are intensified. Prior to Gordo’s demise, he successfully mated with a female named Ashley, as confirmed by an X-ray revealing her pregnancy during a transmitter implant replacement at Toronto Zoo earlier this year.
Like all rattlesnake species, Eastern Massasauga rattlesnakes are ovoviviparous, with internal egg hatching and live birth, as seen with Ashley giving birth at the zoo this spring. Choquette plans to keep Gordo and Ashley’s offspring in captivity until they reach a year old, aiming for their release into the Ojibway Prairie Complex next summer, ensuring Gordo’s legacy continues in Windsor-Essex. Choquette emphasized the importance of preserving this unique tallgrass prairie population of Massasauga rattlesnakes, describing it as a distinctive element of Canada’s natural heritage.
