Sailing The Pacific

Hey,guys im here to tell you about this article I read about It's called Sailling the pacific by Maria Samuela.I think this story is about learning different ways to sail like,using the clouds to see if land is close,or using the stars to navigate through the night and using birds to go and fly out and if they land some where so they know there is land where the bird hes flown and they used ocean swells to navigate

Q1.how did they train the bird to land on an Island?

Q2.How did they use the stars to navigate?

Q3.How can you be a navigator?
