In Ark Mobile you can breed dodos to get larger or smaller. Dodos below 0.8 scale can be mounted on your shoulder and above 2.4 scale they can be mounted and ridden.
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. :)
One time a sarco came to my base and attacked me and my 3 Dodo. I come back about 3 minutes later to one Dodo, completely unbiased. I check it's inventory and I see sarco skin. My dodo, not high level, killed a sarco all by itself, with minimal effort.
