Because argy's spawn in spots with lots of predators, all you have to do is build a wooden spike wall around it when it's unconsious. Predators will get killed on the spike wall and won't harm your argy. I used this strategy with my gallimimus i was taming in the redwoods. I tamed it safely! You can use this with many diffrent creatures to protect them when they're unconsious. The bigger the creature, the more the walls. For an argy, i'd say around 6 walls. I once had knocked a therizino unconsious, and it was killed by dilos. If i had used spike walls, those dilos would have died! R.I.P therizino. Hope thos helped!

Once you get one of these bird attention QUICKLY place 5 or so stone/wood dinosaur gateways in a row, far enough where they don’t connect but close enough where they can’t get out. Place 2 doors, one of each end.

Get it’s attention again and while you’re running through the gateway, be QUICK to open and shut the gate while you manage to escape.

Once trapped and you get out, shoot with tranq arrow and feed raw meat, make sure u feed narco or bio toxin while taming

uhm i was taming a argy then i was freezing so i went home to get a torch and when it was morning i got back there and i didn’t see my argy so i tamed another one and i tamed it so i whistle all follow and it said 3 creatures heard your whistle i got confused and i was going home and i saw the argy that i was taming before and now i have 2 argys

Using a dino to distract the argy is better than wasting resources, things you need will be a tanky dino [on passive] some prime, 30-50 tranq arrows, and a crossbow and wait, i recognize using so narcotics to be safe. I got 12 argy that way including 2 raven/crow colored and 2 chickens. I reccomend using a dino trap on the argys in a group cuz they may kill your tame. Thats a taming tip, enjoy :)

Step 1:tame a flyer that you’re willing to sacrifice

Step 2:find an argentavis to tame I recommend going to the frozen tooth but bring campfires

Step 3:get the argies’ attention with the sacrificial tame

Step 4: land at your preferred taming spot

Step 5:get away from the tame and let the argy start killing it whilst you shoot it with darts or tranq arrows

Step 6:put its kibble or meat in its inventory

Step 7:you will now have an ARGENTAVIS!!!!

Well from what I've learned when taming an argy is

That a trap works best for me captain fat dog's argy trap works best(captain fat dog is a youtubers if you didn't know) I usually use a crossbow and tranq arrows

But I've killed many high level argy cause the cross bow does way too much damage and not alot of torpor

So I use tranq darts and long neck and no wonder the tranq darts unlock on the same level as the argy saddle
