These birds are a super easy tame and are great for food early game the constant stream of eggs keeps the belly full! Not to mention they are a great "fridge" for foods early game as they won't eat eggs or meat!
On mobile, there is a little thing called dodo size. It dictates two things, 1. How you go about transporting the dodo, and 2. What bits you can put on it. You can breed them to get the size you want, for the purposes you want. Little dodos are shoulder birds, medium dodos are regular dodos, and large dodos can be ridden and can equip bits.
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. :)
Dodos are good practice for breeding. They are easy to care for(hand feed them plenty of berries so they don’t starve), and if you fail, you can get prime meat(is it brutal, yes, yes it is.) If you can raise a dodo, you can raise other Dinos.
