Hong Kong's oldest zoo is looking into the sudden deaths of nine monkeys in just two days, including three from a critically endangered species.

The Hong Kong Zoological and Botanical Gardens has temporarily closed part of its facility to conduct thorough investigations and ensure the health of the remaining animals. 

Hong Kong Zoo's Unexplained Deaths of Nine Monkeys

On Sunday, eight monkeys were found dead, and another died the following day after showing unusual behavior. The deceased included a De Brazza's monkey, a common squirrel monkey, four white-faced sakis and three cotton-top tamarins. 

The cotton-top tamarin species is recognized as critically endangered, making these deaths particularly concerning for conservation efforts. 

During a press briefing on Tuesday, Hong Kong leader John Lee shared that a section of the zoo has been sealed off and disinfected. He confirmed that experts have been called in to conduct necropsies and toxicological tests to determine the cause of the sudden fatalities.

Following the initial discoveries, an urgent meeting was held by Kevin Yeung, the Secretary for Culture, Sports and Tourism. This meeting brought together representatives from various departments, including the Leisure and Cultural Services Department and the Department of Health, to discuss the troubling situation.

Ongoing Monitoring and Precautions

The zoo staff observed that another De Brazza's monkey was behaving unusually and needed further monitoring. Thankfully, all 80 other animals at the zoo appeared to be in normal condition.

On Tuesday night, the Leisure and Cultural Services Department released an update confirming that the condition of the remaining monkey is stable, but they have yet to receive test results. Officials are working hard to find answers about the causes of these deaths. 

The Hong Kong Zoological and Botanical Gardens is a historic establishment, first opening its doors to the public in 1871. Nestled in the heart of the busy downtown Central district, the zoo spans about 14 acres and is home to a variety of animals, including 158 bird species, 93 mammal species, and 21 reptile species, according to The New York Times

Since the alarming deaths of the monkeys, the zoo has implemented a comprehensive monitoring program for all its animals. The section housing the mammals has been closed for cleaning and disinfection. 

Park staff noted that two more monkeys displayed strange movements and eating habits, prompting immediate action to monitor their health.
