It's Nearly Impossible to Spot the 500 Sheep in This Photo

— -- A Canadian farmer’s seemingly simple task of finding the sheep on her farm has turned into an Internet puzzle.

The farmer, Liezel Kennedy, posted photos on Twitter last week of her view when she went to round up the sheep on snow-covered land in Saskatchewan, Canada.

Though the farm, Shamrock Ranch, has a flock of more than 500 sheep, Kennedy wrote on Twitter that she, “Could hardly find my sheep this morning.”

Kennedy, who owns the farm with her husband, told ABC News that the photo is not Photoshopped and is an authentic wide shot she took in order to capture all of the approximately 550 ewes in the photo.

"I tried to be far enough out to include the whole flock (once I spotted them)," she told ABC News by email.

The optical illusion is courtesy of the sheep blending right into the landscape, whether it be the snow-covered landscape of winter, now, or in the summer, when the sheep blend in with the tall grass.
