Similarly to real life, these greedy douchebags will try to steal your sandwiches, however if you are drunk enough, you can stay up into the late hours of the evening and have deep insightful conversations with these feathered friends as they simply stare at you in confusion and bark in bird language. In return they will bring you magical fish as a reward.
I had the pleasure of befriending one of these animals. Despite popular opinion, I find ichthyornis birds to be quite charming and graceful. So much that I found myself taming one. After he woke up, I saw a fire in Greg. From then on, we would be best friends. He’d come with me everywhere. From simple resource gathering to Bronto taming, Greg would be there supporting me from my shoulder. When I was too tired to go fishing or hunting, Greg was there to do it for me. He even makes the effort to make sure I get the best meat out of it. He is a quick learner, he went from from level 20 to level 40 in a day. Anywhere I go, he comes. Anything I need, he makes it his top priority. To this day, Greg continues to be my best friend and sometimes we just hang out on the beach or go fishing even when the resources aren’t needed. I thank Greg for his time with me and his endless favors that he has completed for me. Thank you, Greg.
When going to tame one, unequip everything except your armor and put it in a box or tame you leave at your base (far away), then put only food, water, a set of bola and your weapon in your hotbar. Thanks to the new kibble system, you can bring and use regular kibble. Split all trank darts, narcs, etc into singles in your inventory (your weapon won’t care if the ammo is in singles), but it makes it harder for it to steal and eat your stuff. Wait until one is on the ground. Bola it, trank it out with darts. Starve tame it in case it’s friends come calling. When it’s hungry, feed it the kibble. Done!
I was attacked by one while mining flint and it stole my pick. Then it got my pike when I went to fight. That's when I noticed noticed that it didn't actually "steal" what was in my hand, but just disarmed me and dropped it in the ground. Check the ground and see if your stuff is there after they attack you. My pick was laying there near the spot of the initial attack.
