Walkthrough
You will find Gull Hookbeak on a small plateau/hill between the Silver Crimson Skull Coin Collector and Stolen Supplies Collector in combat with Yorrt Strongjaw. Kill Strongjaw first then speak to Gull to begin the quest. Follow the quest marker to the yeti outlined in the quest, Yrrg Snagtooth. After you have done this, kill the yetis around the boss without killing the boss. Weaken him to allow Gull to deliver the killing blow. Speak to Gull once more to accept your reward.

Initial dialogue
Gull Hookbeak
 * "Human interloper, you know not what you have done. No doubt you foolishly believe you have aided me, but you have in fact deprived me of the chance to complete the Rite of Valor and prove myself. If you cannot find another worthy foe for my blade, you shall have to suffice."

Intermediate dialogue
Gull Hookbeak
 * "Yrrg Snagtooth! Yes, my tribemates know him well. This foe is more than worthy and will allow me to complete the Rite of Valor with pride. Those others, however, are beneath me. If you would atone me for depriving me of my earlier foe, you must kill them...but leave Yrrg Snagtooth for me. Do this, and I will be grateful. But if you kill him before I do, you will leave me no choice but to earn my honor with your blood."

Reward dialogue
Gull Hookbeak
 * "You have atoned for your mistake, but do not think this makes us allies. If I see you again, only one of us will walk away from the encounter, and it will not be you."
