Tracy has known Hurricane since he was hatched and watched over him since he started nesting so it's safe to say that no one knows him better than she does.

Not to mention that Tracy is awesome in general, she has raised falcons, mothered them, healed them and I think knows their behaviour better than anyone I know.
Tracy knows more about Peregrines than anyone I know as well! Matter of fact, I bet she was a falcon in a past life! lol She's the bomb!!!!
