If in the redwood biome run to one of the small streams they glitch and don't register as water for you but it does for the terror bird so you can go prone in those streams and the terror bird will lose agro works for carno to.
Everyone seems to limit this to just being a "scout". If you get a high level (170+) the terror bird can easily be one of the most deadly mounts out there. It's speed is unmatched and its ability to glide from any height, if it has the stamina that is, makes it amazing. If you pump HP, speed, stamina, and later on movement speed, you will have an absolute killer. (WARNING: Even high level terror birds will have low weight, only bring your essentials to maximize on speed!)
Perfect mount to explore on the ground. Everyone uses a ptera to get around the map, but on the ground it's a whole different experience. Also this mount is my go to for cave exploring. 300+damage and 180+movement speed is a must.
They are great for most island caves. I usually use them for south and lava cave because they flap right over lava. Then I took one in the yeti cave... yeah um... don’t do that. It won’t end well for you or your birb...
