Sleep tight, baby Baako.

The Belfast Zoological Gardens announced the name of its new baby gorilla this week: say hello to baby Baako. The little boy was born on Aug. 3, marking the first western lowland gorilla born at the Belfast Zoo in 16 years.

The zoo held a naming campaign following the baby gorilla's arrival. More than 600 votes were cast, and the name Baako, which means "first born child," emerged as the winner. Zoo officials are excited about their newest gorilla addition, which is the first child for father, Gugas, and mother, Kwanza.

"Due to Gugas' background, he is genetically very important to the European breeding programme as he is not represented in the zoo population," zoo manager Mark Challis said in a statement. "[A]fter fertility tests last year, it was believed that Gugas would never father any young so we are delighted with Baako's arrival but we also have high hopes that he will be the first of many more!"
