It is pretty much a raptor that can glide through the air. The thing is that it isn't an early tame, which is why it is less useful. Since it's a harder tame than a raptor, you can better tame a carno at that point.
YALL WEREN’T LYING ABOUT THE GLIDING ABILITY- it’s little wing flapping😭😩 they’re not bad, they do have little stamina and don’t do much damage but they’re quick so I would only recommend for short travel also the amount of time they can Glide depends on their stamina too so be careful. -V
Get yourself a flock of these guys amd make sure they are bred and fully imprinted as well. Well they don't have to be bred but just wont be as good. Trust me on this. These guys are amazing as a flock. Watching them devour everything is amazing. Get tbese guys to as much health as possible and you'll be able to tear through alpha Raptors and Carnos with ease. Trust me
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!)
