Hey Sandra,
Like others have said already, Omar's in Lake Forest is my top recommended choice. Good people and good information, plus a host of birds to play with! Also would be Omar's in Yorba Linda and Exotic Bird's by Fran in Cypress.
Here's the web links:
Omar's Omarsexoticbirds.com: Avian, parrots, birds, parrot boarding, parrot cages, parrot food, parrot toys, parrot medications, parrot advocates, psitticine, macaws, amazon parrots, meyers, senegal, cockatoos
Exotic Birds by Fran 9215 Valley View, Cypress, CA 900630
(714) 761-0868
I too would be interested in finding out of a local parrot owners group here in Orange County. Don't know of one yet, let me know!
Regards,
Glen
