Look at them flock to the battlefield! They call those creatures Fowl Beasts. Do you know why they circle around such dangerous places? These overgrown buzzards like to stockpile spoils of war. They're attracted to the shiny metal of fallen soldiers' armour and weapons, just like the birds they're named for.
During Normal Quest, in Chapters 54-2, 55-3, 56-1.
