Each spring as the sun begins to warm the land, the largest gathering of snakes in the world emerges from their underground lairs in Narcisse, Manitoba. They have one thing on their mind - mating.

The male snakes are usually first to surface and they wait patiently for the females to come out. As the larger females surface, the male snakes are eager to mate with them, forming a mating ball, where one female is surrounded by up to one hundred males.

The best time to witness this spectacular annual snake orgy, is the beginning of May.
