Try to contact a club if you can't find anyone thats near you. A lot of these centres are a waste of time, they will be happy to take your money and most aren't qualified to teach you anything about falconry. Falconry is hunting with a trained bird of prey. Try to get yourself in touch with someone that keeps their birds for hunting and get out with them, you will learn a lot more. Bird of prey centres are far removed from true falconry. Maybe someone on one of the FB pages that you mention once they can see that you are keen to learn I'm sure that someone will take you under their wing. Good
