I tell everyone to read scientific papers and studies, rather than a book. It his sometimes very boring, but you glean a lot more info on biology, behavior, and specific habitat, than a stack of books. Bonus is they are often searchable and free online. This is especially true for predator hunting and management. I find that reading both books and papers helps dispel a lot of the housewife tales and myths associated with a certain animal. That last statement is mainly geared toward coyotes than anything else.
