Do not take these guys on in the redwood, lead them out of the forest but even that dangerous because you are right next to the swamp. Bring something big to take down the terror birds and carnos that run around the swamp.then tranq the tigers from a DISTANCE!! (Note the distance part)
I got lucky flying through red woods and found a red one on the ground attacking an argy. While it was distracted, I shot it with tranc arrows and knocked it unconscious. I obviously named her Red. BEST TAME EVER!!!
