an elder hawk  

They spawn around this area 150.29. 5.41, 1330.70

This mob is not that hard to find. You can either spawn it yourself, or go to the southern tip of TS near the centaur camp there. If you spawn it yourself, you must kill lvl 25 Mature Hawks. Any other lower lvl mature hawk will do nothing. If you cant wait for the respawn then make your way to the centaur camp at the southernmost tip of Thundering Steppes. There are normally 3-4 Elder Hawks there at any given time. Enjoy =)

So, maybe not PLENTY by the sabretooth den, but I did run into some there and several by where Obsid spawns (near 823.65, 4.98, 1,029.15).

this is a super rare spawn to be found just north of the south bandit camp. kill mature hawks to trigger their spawn and the drop you need from them for the far seas requisition ts0544 is even more rare than the mob itself. in my opinion, buy a lottery ticket because the odds of winning would be 10 billion times better than completing this stupid quest.
