I wondered about the greywing mutation... it's hard to tell what they are, especially with his flight feathers clipped! But the flights look like they might be a lighter colour, too. Also I was confused because I heard that greywings were supposed to have a generally diluted body colour? I don't know.
Brother and sister, eh? No wonder they're always bickering
Cirrus is a sky blue recessive pied female and Katsura is a light green recessive pied and either full color grey wing or clearwing. sometimes it's hard to tell the difference in wing patterns. But I think Katsura may be a male. I'm not positive though.
Both females. I would say the first is a recessive pied cobalt hen, and the second is an opaline recessive pied full body colour greywing light green hen.
Wow, what a mouthful!
I admit, I'm glad to hear they're the same gender, though...
Thanks everyone! You've all been incredibly helpful, I came to the right place! If those flight feathers grow in orange or something I'll be back with more pics
Oh, speaking of flight feathers, one last question: you may see in the pics of Cirrus's wings that there are a couple of feathers, one on each side, that appear to be unclipped, sticking out the bottom. Should they be clipped? Were her wings clipped too early, or something? I've heard it can be dangerous to have them clipped improperly, and she is already not as strong a flyer as Katsura (although Cirrus is the baby of the clutch). I was reluctant to do it myself since I have not done it before, but if it's more dangerous to leave them...?
