The zoo might be silent of excited visitor chatter, but there’s still plenty of animal sounds to hear each day.
And our 70-strong Humboldt penguin colony are certainly one of the noisiest species on site!
Penguins communicate by vocalising, with Humboldts making three different call sounds.
The birds have specialised throat structures which enables them to emit the noise, which has been mistaken for donkey braying!
Watch how they tip their heads right back and spread their flippers, with every penguin producing a unique sound, which is identifiable by the other penguins in the colony – particularly useful for locating your partner or parent!
