Chapter 8: A
Feather # 3 - Black kite
Look around for information about the island. Arriving at the market you will find a small turnoff to a green area where some islanders are sitting. Amicia wants to interview other residents who are in the area with the stairs/seats. Run up to the tree behind them to collect the feather.
Chapter 9: Tales and Revelations (Entering the sanctuary)

Chapter 10: Bloodline (The old temple)

Chapter 11: The Cradle of Centuries (Byzantine technology)
Feather # 6 - European goldfinch
Explore the underground area. After you have used Greek fire for the first time to be able to force open a door, you will find another barrel in the next room on the right-hand side, which you will detonate with your slingshot and ignifer. Behind it you will find the feather of the goldfinch.
Chapter 12: The Life We Deserve (Ruined village)
Feather # 7 - Greylag goose
