I am really new to falconry as a whole and have spent the most part of my free time watching YouTube videos. one thing that keeps coming up is that this sport is a lifestyle change. what does that really mean? what is the day to day operations and real cost? any information or a point in the right direction would be greatly appreciated.

You're a bit far but one of the best in the world places for watching migrating hawks is Hawk Mtn in eastern PA. They count each of the birds .When in a day you can see 1000 or more of one type of hawk you will be in total amazement !! That should be on your list.
To get a permit you deal with the state .This takes total commitment as it's a long term project .Once you get the permit you can start raising birds and hunting with then. I don't know the PA rules though.

The USFWS has turned control of falconry over to states that meet or exceed the old USFWS rules (I believe PA qualifies).

You'll neeed:

1) To pass the 200 question written exam at 80%
2) Obtain a sponsor for the first 2 years
3) Build a facility and have it inspected by the state DNR
4) Then & only then can you obtain a permit to trap a wild passage bird or buy a captive bred bird (you'll be limited to one bird on permit for the first 2 years).

Plan on spending $10,000 in the first year or two in facility/gear.

Also plan on driving alot - I'll have put in 20,000 miles in the 2013 season (and I live in one of the best falconry areas in the world).

Finally, plan on 1.5 hours per bird per day on non-hunting days. Up that to 3-4 hours per day on hunting days. (You'll be required to hunt 3-4 days a week for a minimum of 4 months per year in order to keep your license.

Worth it? It is to me.
