If you have to pick up a dodo(a very early tame, likely your first), choose a female. Dodo eggs are able to be made into basic kibble/dodo kibble(depends on the playing platform), which can be used to tame some powerful early tames.
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. :)
