I've done a lot of studying since our last conversation. The Birdkeeper magazine and Terry Martin's book on genetics. I'm looking at the pallid blue and platinum blue cocks and I can't seem to see any difference. As I understand it, the platinum is supposed to be lighter than the pallid. Since the breeder of my "platinum blues" really didn't know genetics (he called them silver) I am not sure they are platinum blue or pallid blue. I do have pallid that I'm using in my orange birds and I would love to know. Is there any way to tell for sure? Any breeding tests?

I do have pallid that I'm using in my orange birds and I would love to know. Is there any way to tell for sure? Any breeding tests? I'm afraid you are getting way beyond my Red-rump knowledge here Nancy! All I can do is provide a quote from Terry Martin's old Genetics-Psittacine Yahoo group, which i snow unfortunately defunct. Also unfortunately the many photos which used to accompany many of the discussions are also no longer available. This was a discussion that followed a couple of photos of Red-rumps and Terry's contribution was the most relevant of those in the thread, from back in 2008. Pallid Blue (Lime Blue) should have a lot more colour (melanin) in the back than your birds. IMO they are definitely PallidIno Blue (AlbinoLime)
I also would suspect Mick's Limes as being LutinoLime (PallidIno) since they are as pale as a Platinum. Unless of course all this is the photographs leading us astray (perhaps with too much flash washing the colours out?).
A Lime should have nearly as much depth of melanin colour as a Cinnamon, but not as brown, more grey-brown. At least 50% of the colour of a Normal bird. Your photos show birds with much reduced melanin colours.
When you breed with them, if they throw Ino daughters then you have your definite answer. Terry
Hope this helps a little bit - some photos would be interesting to see though cheers, Mike |

I've been able to post quite a few pictures on the Red Rump Facebook page. It was there that I discovered my cinnamon opaline hen was actually a pallid opaline. I do have both of my blue pairs photos posted there. From Terry's quote I do think they are platinum blue. I actually have a pallid blue opaline cock and he does have half the melanin. Where I am going to have fun is when I start getting PlatinumPallid and pallidIno cocks! I'll only know the color because I know the genetics! When I get some of these unusual colors I'll post them. Your help has been invaluable, I've already been passing on whatever I have learned! God Bless! Nancy

Hi Mike!
I may have another question that I'm hoping someone can answer. I've been using 2 albino red rumps for the lutino factor. I want to eventually breed an albino cock. I'm using a bird that carries opaline also. My question is will I be able to tell the difference between a blue ino and a blue ino opaline? Gen Calc says I will get both. Any ideas from other birds? I know, crazy question. Any answers are helpful!

I know, crazy question. Any answers are helpful! I'm guessing here, but a blue ino has removed all yellow and blue pigments to leave a white bird and I would think that would include the opaline markings as well. I had a look in Terry Martin's book and he suggests that is what will happen. He does mention that a cinnamon blue ino opaline cockatiel retained a pale cream suffusion, so perhaps faint opaline marking may be visible? cheers, Mike |
