They are a good source of food early in a playthrough. Build a small thatch shack, put one male and as many females as you want and you have a pretty decent supply of raw meat, hide, and exp (From leveling them up and hatching) considering how early you can do it.
For the guy who said that it would be cool if a dodo could sit on your shoulder: on ark mobile, a dodo smaller than .75 can in fact be carried on your shoulder. Dodos over 2.6 can be ridden. Fun fact. :)
