On mobile these can be bred to get insane sizes, like huge, bigger than an Allosaurus and they have 8 abilities unlocked at certain sizes. I only know 2 abilities, one is the dodo gains an immense amount of speed and charges towards the target. The other that I know of is that it jumps up and slams into the ground which stuns surrounding enemies. Do not underestimate the potential that these have on mobile, they can become beasts.
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. :)
These little dudes are really fun to breed! You can breed them bigger so they are rideable, smaller so they can be shoulder pets, or just for the colours! I’m in ark mobile and currently breeding them to be bigger, and it’s very entertaining :)
