How do you keep a polar bear cub cool in 30C heat?

Park staff were concerned Hamish would not know how to stay cool in the recent high temperatures

Measures have been taken to keep a polar bear cub cool after temperatures rose to more than 30C in Scotland.

Six-month-old Hamish shares an enclosure with his mother Victoria at the Highland Wildlife Park at Kincraig, near Aviemore.

While Victoria knows how to keep herself cool, park staff were concerned the cub would not.

As a result, during the day they have had to stay in a shaded area which is not visible to visitors.

They have also been given blocks of ice with treats, such as pieces of fruit, frozen inside.

In the evening, when it is cooler, the pair have been able to enter the rest of their enclosure.

The Royal Zoological Society of Scotland-run park's two adult male bears, Arktos and Walker, have been cooling off in a pond in their enclosure.

They have also been given treat-filled ice blocks.

During a previous spell of hot weather, park staff said polar bears can experience high summer temperatures in areas of their natural habitat in Canada.

Earlier this week, temperatures in Aviemore exceeded 30C.

The high temperatures have also been felt widely across the UK, and polar bears at Doncaster's Yorkshire Wildlife Park also sought out the cool of a pond in their enclosure during the hottest periods of the past few days.
