London Zoo does annual animal count

One of the lemurs that makes up the 10,000 animals at London Zoo

It's that time of year again - when keepers at London zoo tally tortoises, add anteaters and count camels in their annual stock take.

They do it to keep tabs on the over 10,000 animals currently living at the zoo, and see which species have had babies.

The information is then shared with zoos around the world, to aid conservation programmes worldwide.

Looks like the penguins broke the ice quite successfully with their counting keeper

Among those counted were the zoo's colony of 65 Humboldt penguins, which are a vulnerable species.

This means they are threatened with extinction in the wild, so at some point if nothing is done, there could be none left.

Five new pairs were added this year and the hope is that they'll have lots of baby penguins in years to come.

They seemed particularly interested in the keeper doing their count!

Very helpful squirrel monkeys

Another animal that clearly wanted to help out were these Bolivian black-capped squirrel monkeys.

Better kept busy by the stock take than their usual monkey business...

One of the seven gorillas at London Zoo

Western lowland gorillas are critically endangered in the wild, so when two baby gorillas were born in February 2024 - Juno and Venus - keepers were over the moon.

There are now seven of them at the zoo in total - look how cute they are!

Even Lemurs need to keep toasty!

But obviously given the time of year and the incredibly wintry weather we've been having, there's one thing that's just as important as getting the numbers right - keeping warm like these lemurs!
