In a heartening turn of events, Gordo, the Eastern Massasauga rattlesnake, met his demise on Matchett Road last summer, but his genetic legacy lives on. According to a local expert in reptile conservation, Gordo successfully bred before his passing, resulting in the birth of seven baby rattlesnakes who are now being nurtured for eventual reintroduction into the local habitat.
Jonathan Choquette, a biologist holding a PhD and heading the Ojibway Prairie Reptile Recovery program at Wildlife Preservation Canada, expressed his enthusiasm for this development. He noted that the offspring of Gordo carry the distinctive Ojibway genetics in their blood.
The Eastern Massasauga rattlesnakes face a critical situation in the Windsor-Essex area, with their numbers dwindling to possibly less than 10 individuals. These snakes, the only venomous species in Ontario, are categorized as critically endangered throughout the province. Despite their venomous nature, they typically avoid conflict and only resort to biting when provoked as a last defense.
Gordo, a prominent male specimen, was brought to the Ojibway Prairie Complex with the aim of bolstering the local rattlesnake population. Tracked by Choquette’s team, Gordo’s lineage could be traced back to Eastern Massasauga rattlesnakes rescued in LaSalle over two decades ago.
Tragically, Gordo was discovered dead on Matchett Road in September 2025, likely a victim of a vehicular collision, with his identity confirmed by an implanted electronic transmitter. Choquette emphasized the precarious state of Massasauga populations in Windsor-Essex and stressed the importance of conservation efforts to ensure their survival.
Before his demise, Gordo successfully mated with a female rattlesnake named Ashley, as observed by Choquette and his team. Confirmation of Ashley’s pregnancy came later when she underwent a transmitter implant replacement at Toronto Zoo, revealing the presence of eggs through an X-ray.
Being ovoviviparous like all rattlesnake species, Eastern Massasauga rattlesnakes have their eggs hatch internally, leading to live births. Ashley gave birth to her offspring earlier this spring at the zoo. The young rattlesnakes, offspring of Gordo and Ashley, will be kept in captivity until they reach one year of age, with plans to release them back into the Ojibway Prairie Complex next summer, continuing Gordo’s legacy in the Windsor-Essex region.
Choquette highlighted the significance of this population, noting that the Ojibway Prairie Complex hosts the only tallgrass prairie population of Massasauga rattlesnakes in Canada, representing a unique aspect of the country’s natural heritage.
