It's World Orangutan Day so Twycross Zoo in the UK did something a bit different by letting people with red hair in for free, the idea being that red hair is relatively rare and so are our orangutans.

There are four Bornean Orangutans at the zoo at Twycross Zoo - Batu, Kibriah, Maliku, Molly.

This video shows the four of them in their enclosure as well as crowds of people enjoying the zoo.

Raining cats and dogs but that doesn't stop people from turning up here at Twycross Zoo, Atherstone England on World Orangutan Day and the Zoo controversially gave all red heads free entrance. Any shade of red, just no wigs, but dye and spray dye is fine! Some calling it gingerism others like the people turning up today think it's a great idea not just because of the free entrance but to highlight the Orangutans and the dangers they're currently facing in the wild. At the Twycross Zoo there are 4 Bornean Orangutans: Batu, Kibriah, Maliku, Molly.
