Adopt an orphaned orangutan
Orangutans are on the brink of extinction. Help provide the care and rehabilitation
they need to return to the wild.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

It's #TongueOutTuesday, and we have a sweet smile for you from Ficz, a #Orangutangutan living on Badak Kecil Sanctuary Island.
While delivering supplemental food, our technicians recently observed Ficz sitting on a tree branch at the island's edge, consuming additional fruits such as pineapples, watermelons and bananas.
After eating, Ficz climbed 6 to 10 metres higher in the tree, where he lay down to rest.
Keep on enjoying your island life, Ficz!

Happy World #RedheadDay!
Today, we invite all redheads—and everyone connected to a redhead—to join "Ranga and the Redhead Revolution".
This beautifully illustrated children's book by author Rachel Paget tells the story of Rachie, a girl who has always been teased for her fiery red hair, earning her the nickname 'Ranga'. However, when she discovers that #orangutans—the original 'Rangas'—are on the verge of extinction, she decides to reclaim the name and fight for a cause greater than herself.
The book is a heartfelt reminder that when we inspire others with our unwavering passion, we can become a powerful force for change in saving the critically #endangered orangutans and their #rainforest homes.
#Join the revolution! Kicking off today, the book will be sold internationally via Amazon for just AUD $13.20 per paperback. For a limited time, 100% of profits will go directly to BOS Australia to support our vital orangutan #conservation work.
