A city in Canada became famous for being home to one of the most incredible (and frightening) phenomena on Earth. Every year, more than 75,000 snakes pass through the area for a joint migration.
The event, which takes place every year in Narcisse, in the province of Manitoba, is primarily composed of eastern gartner snakes that emerge from their dens after hibernating through the winter.
The gathering occurs in the spring and attracts both wildlife enthusiasts and scientists, who come together to witness the extraordinary number of snakes coming out in search of warmth and mating partners.
During this time, as part of the breeding season, male snakes engage in a courtship battle to find a female, using pheromones to create a kind of “mating dance.”
For decades, the snake dens in Narcisse faced major setbacks caused by traffic on the roads, and thousands of snakes were killed annually as they crossed Highway 17 during their migration.
This posed a significant threat to the survival of the gartner snake population, and to combat this, conservationists built special tunnels under the road and installed snow fences at the site to guide the snakes safely back to their dens.
These efforts were successful, and the number of deaths dropped significantly, which, in turn, further increased the gartner snake population.
As a result, the event in Narcisse has become a critical ecological phenomenon, supporting local biodiversity and providing experts with valuable information on reptile behavior.
