SPA = Breeder/aviary
FL = Florida
98 = Year of birth - does 1998 sound about right?
079 = ID
Edit: I also did some research later on, and found this page: http://www.pamperedpeeps.com/bandsbreeders.htm
Theres a long list of breeders, and only one fit the leg band’s decoding you mentioned:
SPA (Silver Shady Pines Aviary)
Lake Worth FL
I wouldn’t bet my life, but I have a bell ringing inside my head, that would be the breeder of your bird.
