These annoying flyers can be used to aid in taming otters. Just set the hunt and retrieve feature on it, make it attack a fish, and as it comes back to you grab the fish and walk up to the otter and press the button to tame. Otters are quick tames, and provide insulation from both the heat and cold which directly depends on their melee stat. They can also hold multiple artifacts in their inventory. Can be found in shallow rivers.
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.
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!
