When taming look in the bottom right hand corner it will tell you when to feed it! (For Xbox use y to feed when mounted) if you trap it and it’s not calming down just knock it and wait until it’s up again to start taming!
Don’t know if this helps but there’s unlike the others in western zone a 3.000 percent chance of finding a Eques if I spelled it right and that’s 3% if you didnt know and like a 25% chance in the island 70% in south zone The island 0.0001% in red woods hope it helped?!!!
You can feed it then use a bola (which doesn’t lower effectiveness) and after that use fence foundations and walls to keep it in place and ride it for the duration of the tame. No need for it to run around randomly.
On the southern end of the Island, just east of the first artifact cave, there is the small island with the A shaped boulder is. Going north of that, upriver, you will come to an area where the river splits. Sometimes there can be around 3 trotting around on the land splitting the river
