Hong Kong welcomed the birth of its first locally born giant pandas on Thursday, with their mother becoming the world’s oldest first-time mother of its kind on record, the theme park that houses them announced. Ying Ying, the mother, gave birth to the twins ‘one male and one female’ at Ocean Park just a day before she turned 19 years old, the park said in a statement.

She and her partner Le Le are the second pair of pandas gifted by China to Hong Kong since the former British colony returned to China’s rule in 1997.
