Unlike most quest-related items, this will continue to drop beyond the amount needed for the Related Quests. Some will drop even when you do not have one of the listed Related Quests. This allows you to build up a supply of this item for future use.
Note: Each Thornose Seagull will drop 1-2 Seagull Leg Meat! Also, Seagull Leg Meat will stack above the 10 required and will continue to drop so you can build up stacks of it to be turned in all at once. You must have the quest to get the drop but it can be completed at the time and the seagulls are close to the quest giver. This makes [Daily] Consequence of Stealing Fish an excellent candidate for Daily grinding.
