These guys actually do have some use. If you just scatter them around you're base and have them on neutral, if something does get in your base it'll aggro on the dodos and you'll get a message saying you're dodo died, alerting you of the intruding creature. It'll also trigger anything you have guarding your base, like in my case, my dilos, my trikes, and my raptors.
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. :)
