Do you have to register to go Thanks

no

You do not have to register. They are open Thursday through Saturday and you pay once you get there to get in. They have tours once you get in that are included. You can walk around without a tour guide if you wish to.

Tours, which are really worth it because you get to see the birds in flight, are usually twice a day. Call ahead.

If they are having not a special event, you can just go

Pretty sure they just take donations if you want to walk around you want to get in a tour certain times a year you might want to call ahead
