Someone I work with is getting a Lord Derbyan parakeet this weekend. He's had two over the years and lost his last one just a few months ago. Another one has come into his life and this bird is predominately yellow. Has anyone seen this particular variety? It's mostly yellow like a golden conure is, but it is definitely a Derby. I'm trying to get him to give me a picture so I can post it and try to figure out what the mutation is. We thought Lutino, or maybe opaline but that doesn't seem to be it. I'll post a picture if he gives me one.
