Squirrel monkeys, Sumatran tigers and Humboldt penguins were among the animals that had their statistics recorded at ZSL London Zoo’s 2022 annual weigh-in last week. With more than 14,000 animals in their care, ZSL London Zoo’s keepers spend hours throughout the year recording the up-to-date heights and weights of all the animals – information which helps them to monitor their health and wellbeing. The data is added to the Zoological Information Management System, a database shared with zoos all over the world that helps zookeepers to compare important information on thousands of endangered species. “We record the vital statistics of every animal at the Zoo, from the tallest giraffe to the tiniest snail,” says Daniel Simmonds, deputy animal manager. “This helps to ensure that every animal we care for is healthy, eating well, and growing at the rate they should, as weight is a key indicator of health and wellbeing – a growing waistline can also help us to detect and monitor pregnancies, which is important as many of the species at ZSL London Zoo are endangered and part of international conservation breeding programmes, including today’s Sumatran tigers and Vietnamese giant snails.” Three Sumatran tiger cubs which were born at the zoo in June will be weighed next month at their first health check – which takes place at the age of three months.

Last week saw the annual weigh-in of animals at ZSL London Zoo and all creatures great and small took part – from the Bolivian black-capped squirrel monkeys (pictured above) to the giant Galapagos tortoises and the tiny midwife toads (both pictured below). With more than 20,000 animals in the care of the zoo, the keepers spend hours through the year recording the heights and weights of all the animals. It’s an important task – the information aids them in monitoring the health and wellbeing of all those in the zoo. “It helps to ensure that every animal we look after is healthy, eating well, and growing at the rate they should – weight is a particularly important indicator of health and wellbeing,” says the zoo’s animal manager Angela Ryan. “A growing waistline can also help us to detect and monitor pregnancies, which is so important as many of the species at ZSL London Zoo are threatened and part of international breeding programmes, including today’s Asiatic lions and big-headed turtles. By sharing information with other zoos and conservationists worldwide, we can all use this knowledge to better care for the species we’re striving to protect.” For more, see www.zsl.org.
