This photograph taken on January 6, 2016 shows a hatchling inside an incubator at a vast aviary in Bogor, south of Jakarta. Barely a few days old, perched on a nest of twigs inside an incubator, a newborn Indonesian songbird – cherished for its melodious chirp – tweets weakly as a tiny metallic ring is attached to its leg. The tag shows potential buyers the chick was bred in captivity. It's an important symbol, which shows it was not trapped in the wild and smuggled, an illegal trade which sees birds packed in their thousands in shipping crates or stuffed in plastic bottles before being sold in giant avian markets in Indonesia's major cities.

A rare white giraffe grazing in the African bush. Omo the white giraffe has been spotted roaming around Tarangire National Park, in Tanzania, along with the rest of her herd who dont seem to notice her unusual colouring. Ecologist Dr Derek Lee, founder and scientist at the Wild Nature Institute, caught the pale giraffe on camera. Derek, 45, said: Omo is leucistic, meaning many of skin cells are incapable of making a pigment but some are, so she is pale but not pure white with red or blue eyes as a true albino would be.

These young monkeys look a little sad as they sit close together in the water and one sticks out his tongue to catch the falling snowflakes. The wild Japanese macaques sit in the hot water, which is around 40 degrees, as a way to keep warm in the minus five degree Celsius weather. During the winter, the macaques spend their days warming in the hot springs before returning to the surrounding forest at night.
