These pictures show the moment a peckish crow was caught unwrapping and munching on a Mars bar.

Lorna Williamson, 56, witnessed the bizarre scene in a children's play area where youngsters had left the treat.

She managed to follow the bird with her camera and took a series of snaps of the bird unwrapping the chocolate and then burying it for later.

These pictures capture the stunning moment a peckish crow was caught unwrapping and munching on a Mars bar

The greedy bird was snapped perched on a frozen surface while picking away at the chocolate bar. After a short struggle the crow manages peel back the wrapper

The crow soon returned and was snapped gripping the chocolate treat in its talon

Ms Williamson, a care worker from Deeside, Aberdeenshire, said: 'I'm interested in the natural world and birds.

'I saw the crow picking the chocolate bar out of the wrapper. It can be quite hard to open but it was having a good go at it.

'I had my camera with me and decided to step a bit closer.

'The bird flew on the roof of a play hut for small children.

'It took the Mars bar to the top of the roof and was picking at it.

'I watched it for a while. It flew off to a high branch and eventually came back down to the ground.

After picking at the Mars bar for a while, the bird eventually buried it to store it away for safekeeping

'It just picked at it a little bit and then buried it. I thought it may come back for more later. I was just surprised that the chocolate was still inside the wrapper.

'I'd like to raise the issue of children leaving their food and wrappers behind. Why the Mars bar was on the ground only they know.

'I've since learned that chocolate is actually dangerous for birds. They will eat anything humans leave behind.'
