Even though Zan and Streak (a pair of bald eagles) were important helpers of The Band (Soren, Glyfie, Twilight, and Digger) in The Capture they did not appear at all in The Owls Of Ga'Hoole! 

Zan and Streak should have been in the movie! Since there are no ofiicial pictures of these eagles I'll just have a photo of a real eagle pair. However, Streak makes a minor appearance in the video game for this movie.
