When the dodo was alive there was no photography, so we don't know exactly what it looked like.
This is an old painting of a dodo. It also shows some other animals, like parrots and ducks, that are still alive today. We can see that the parrots on either side of the dodo look quite realistic - do you recognise them?
If the parrots have been drawn well, maybe the dodo has been drawn well too? What do you think?
