When fighting the fearsome dodo never go head on. I know from experience that dodos in a pack a hit hard took my 150 perfect tame giga out lost it to a lvl 1 dodo. Beware they are some of the most fearsome Dino's on the island. My tip to you is to only encounter from afar with ranged weapons such as rocket launchers. The best way I have found is to drag it out into a body of water, but beware they swim really fast, but get under then a pike with several friends.
Encountering this creature will mean your imminent death. If you want to take this you need a tek trap, as they can break metal. It can outrun almost all creatures. It will take approx. 350 shocking tranq darts for a level one and 1240 for a 180.
