I talked with him today and he doesn't know any breeders in the US at all. He has also never exported any birds and doesn't plan on doing so. He and his wife are in their mid 70s and only plan on one more breeding with the pair they have now next season, the other pair has stopped breeding two years ago.True but Tinker's breeder might have/know of a U.S. breeder she could refer you to.
They are the removing the nesting equipment and letting the adults enjoy the 20' by 16' sun room for however long they can.
