Sumantran Orangutan

(Pongo abelii)

The orangutan belongs to the great apes, and as a forest-dweller it feels most at home among the treetops. Both species, Bornean Orangutans (Pongo pygmaeus) and Sumatran Orangutans (Pongo abelii) – the latter can be seen at the Zoo Berlin – are heavily endangered as their natural habitat is shrinking at an alarming pace.

Mum's the Greatest

Orangutan mothers are very loving and maintain a close connection to their offspring. Children stay with their mothers for up to seven years – that's how long it takes before orangutans give birth again. Adult males are mostly solitary animals.

...Sumatran orangutans are principally threatened by the deforestation of rainforests, the calls of grown males can be heard from up to 5 miles away and they build a new sleeping nest amidst the treetops every single day?
