well I live in teh redwoods/volcano area...and no dodos there. As I want to get the costumes, I went to the nearest dodo nest and caught some. Then I realsied i must transport them somehow to my main base...so I started building a base on my quetz. After I did this I went with the quetz there and tried to make them climb on the ramp...did not work. So I tamed a pteranodon killed other things crafted a saddle...Then ! I picked them up one by one and put them on the quetz base but...they were slowly leaking through the walls..Or if the quetzal moved or took off, they would leak rapidly out... So I gave up after a 5h operation, said screw you ark, went back home and spawned dodos in a pen..because well you can t play this game without cheats.
