A pair of monkeys, listed as critically endangered in the wild, have been born at Belfast Zoo.

Pied tamarins Alex and Charlie are said to be "doing great" after being born to dad Rickety-Rick and mum Molly.
The World Conservation Union has reclassified pied tamarins, which come from the Amazon region of Brazil, from endangered to critically endangered.
They are moving a step closer to extinction. Only seven zoos worldwide have pied tamarins in captivity.
The primates are being threatened by habitat loss in their native Brazil.
They live in a very restricted area in the heart of the Amazon.
In the wild, the animals forage for food including insects, ripe fruits, gum, and nectar.
The head-body length of pied tamarins ranges from 21 to 28 cm, with the tail up to 33 to 42 cm long.
