Lutino and Gray Budgies...Males or Females?

My first parakeet had gotten this REALLY annoying habit of copying the baby chicks (chickens) "HELP ME" chirps. I'm talking, perfection.

I realized that she needed more companionship than I was able to give (working full-time along with the reunion of my horse! Whoop!). So, I got her a little buddy. He's several months younger, but adorable. They've been together for an hour and are already preening each other.

The little male (I'm assuming) is apparently asserting his dominance in the pecking order. I've noticed him on the higher perch more often than my Lutino. Is that a normal thing for a new bird?

I'm also "assuming" that the Lutino is female, although it is very difficult to determine sometimes, especially seeing as how she was able to mimic the chick noises so easily and perfectly.

If anyone can weigh in on this?

Supposed male:


Lutino:


Together:


Also, if you can tell me any info regarding either color/mutations, please let me know! I am very interested in the gray color...it's just kind of unusual. The Lutino is simply beautiful in itself.

 

That's what I had thought, but the Lutino gene can cause the cere to be a bluish color in females also.

 

Yes, that's a good link but the author doesn't seem to go over the Lutino gene. Here's an example of what I'm talking about:

These aren't the best descriptions/links but I was afraid to link to another forum.


Edit: I've had the "regular" blue, green and even pied budgies and have paired them successfully, but this Lutino is throwing me for a loop. I have had budgies before, approximately 10 years, but had to give them up due to allergies. I was recently able to get them again thanks to some awesome allergy meds!

 

I wish I had never gotten that canary...it has skewed my entire outlook on female birds. The canary I got was a brilliant singer even though the females aren't supposed to sing.


I'm not trying to tell you all you're wrong...I'm just utterly confused by what I'm reading online as well as on some forums I'm on. Some are telling me it's a pair and others are telling me it's two boys. If it's a boy, so be it. I'm just trying to make sure they will get along. I "believe" two males can get along, but I've always separated into male x female pairs.
