Our youngest elephant Bala, was born in January 2013 to mum Sithami, just a few months after Hari, who was born in November 2012 to first time mum Sundara.
Elephants are very intelligent and can live up to 70 years. Over time, we've built a fantastic relationship with our herd, always delighting in watching newcomers develop from mischievous teenagers into mighty adults.
Our bull elephant Aung Bo joined us in October 2012 and will hopefully play an important role in our conservation breeding programme.
We also have one other female, Maya – see how quickly you can pick her out. It won't be difficult, as she's a big attention seeker!
Big is a key word because Asian elephants can reach three metres tall. That means we give them lots of space in our Asian Forest enclosure.
In India and south east Asia where wild herds live, elephants roam large areas of scrub and grasslands.
For many years elephants were hunted and killed for their ivory tusks. Nowadays they face another equally dangerous threat to their survival because much of their natural homeland is being taken over by farmers and developers.
To help counter this we've set up an Asian Elephant Conservation Programme to figure out problem-free ways for elephants and farmers to happily share land.
Every time you visit us here at the zoo you help us to keep that programme alive and ultimately to reach our goal of protecting Asian elephants for future generations.
