This errand becomes available after completing the side quest “Hunter’s Blind”. Talanah will ask you to hunt bring home a Stormbird and Thunderjaw trophy. At this point, you should have at least the Shadow Ropecaster. This amazing weapon can significantly make hunting large machines a whole lot easier. Make sure to attach Tear or Handling mods on it. Also, make sure you have enough wires to craft heavy tie ropes so you can make more and basically keep your targets tied down for the entirety of the battle.
Thunderjaw Blood
There are several thunderjaw sites in the middle of the map but if you want to start off from a safe locatiom, there’s one near Lone Light.
Stormbird Blood
One stormbird site is located north of the Great Run hunting grounds.
After getting the Trophies, go upstairs to present them to Ahsis, only to find that he’s not there. Go downstairs and ask Ligan where the Sunhawk is. Completing this errand will immediately start the sidequest “Redmaw”.
