What did Frightful need to be able to migrate south?

When a light snow covered the Schoharie River Valley, Frightful’s bird sense urged her one last time to leave or die. On an unusually warm day in early November, she stepped to the open sill of the bell tower. She had caught no food for two days. She must move south.

its everything except for telling nonfiction and using first person

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.
