A big birthday bash has been thrown in Edinburgh Zoo for its oldest resident - a 50-year old chimp called Ricky.
Ricky celebrated in style by unwrapping presents with his chimp friends under a colourful birthday banner.
Ricky was left orphaned when he was young and he spent his early years on a merchant navy ship.
He came to the zoo in 1966 when there were just two other chimps here. There are now over 20!
His zookeeper said he's one of the most popular of his group and is a big hit with the female chimps.
