The wildlife presenter lent his tones to the women's curling championships at the Winter Olympics in Sochi after being asked to by BBC Radio 1 presenter Greg James.
In his commentary, the 87-year-old describes the curling stones as "walnuts" and the rink as a "frozen river". He also claims the "ritual" is undertaken by the sliding curlers to "mark their territory".
He continues: "This is nature at its most vulnerable. The aim of this ritual is to land your walnut in the centre of the nest.
"The frisking is frantic and often futile, making no difference to the net thrust, but it is playful and what makes this game the sliding curlers play so magical. Look how happy it makes them."
The Scots women's team won bronze at the Winter Olympics today after beating Switzerland 6-5.
Meanwhile, Dyson has released a video of curlers using their vacuum cleaners to play a stone.
The video aims to find out whether the vacuums, created by British inventor James Dyson, can outperform the traditional curling brooms on the rink.
