That is interesting. What is your guess on my Nemo? I think that Natascha said once she thought he looked like a boy.
Meyers tend to be slightly dimorphic in chest color. The cocks usually have a lot of black barring on the chest and my Hobbs was six when I got him and he had barring very closely lined up all down his blue chest. Trix, my hen Meyers, has just a few black bars here and there on her breast and she is 9 years old now. The blue on the back and rump on my subspecies is much darker, more royal in color. The one you are looking at has a greener breast and a moderate black banding on the chest. I assume this bird is female, but not knowing the subspecies, I cannot be sure.
