No Bat is an Island

With Tree Haven now destroyed, Frieda announces to the colony that they must start their winter migration earlier than planned. The mother Silverwings use their echolocation to transmit a sound map into the minds of their children, that way they will be able to find the winter roost. Ariel transmits the map to Shade, although he is not totally sure that he got it all. Still, Shade is determined to prove himself by making the migration. Filled with both hope and despair, the Silverwings take off on migration. As they fly along, Todd flies up to Chinook and gives him a cold reminder that it was just as much his fault as Shade's for losing Tree Haven; if he hadn't taken up Shade's bet, nothing would have happened. Meanwhile, a brutal storm erupts and an untimely lightning bolt causes Shade to drop out of formation. Bathsheba sees this as an opportunity to build a case against Frieda's leadership, as she had said before that Shade was too small to make the migration, so they should have just given him to the owls anyway and saved their roost. Shade wakes up and finds himself on the shore of a deserted island, and narrowly avoids an attack from three crabs. After navigating a series of trees and totem poles, Shade stops to rest in the wreck of an old boat. There he meets Marina, a young, forest-wise female Brightwing with a silver band on her forewing. Having never seen another species of bat before, Shade does not know what to think, but Marina eventually decides he can hang out with her. The two go out hunting and share life stories. Marina was living alone on the island because her colony banished her for having a band. They felt that her band would bring bad luck to the colony. Shade recalls his looking at the sun and being separated from his colony. Marina leads him out to sea where orca whales swim. She shows him how to ride the spray from their blowholes. Unfortunately, Marina gets caught off guard and is swallowed by one! Shade gets on the orca's back and covers
