|Siv (Burrowing Owl)|
|Species:||Burrowing Owl (Athene cunicularia)|
The 'Blue Brigade' are burning the area around where Siv lives. Her mother, Kalo, is refusing to hand over a book to Field Marshal Cram. The Striga threatens Kalo, and when she calls out to her brother, Cory, the Striga declares it blasphemy, because he was named for Coryn. Kalo then calls to Siv, her young daughter. The Striga says that it is blasphemy too, as she was named for the queen Siv, but the Burrowing owl family escapes. Kalo, however, is to be burned.
Kalo escapes being burned to death when Coryn comes to her, and they go to the Great Ga'Hoole tree disguised as Green owls. After the battle with the Striga and the Blue Brigade, Kalo's family, Siv, Cory, Grom and Bruno come to the Great Ga'Hoole tree.
