I can normally tell the difference

but, these guys are so yellow chested... I know that the hen is yellow sided, and the male also classed as yellow sided, hut he has the light head, beak and feet, which would make him a cinnamon-ys, equal a pinapple...

What do you think:

I have no idea, but they are very cute though

Lene... they are very interesting! They look like very yellow cinnamons but not quite pineapples! They have no red! Is there anything else in there? They are amazing looking!!

Whatever they are they are awfully cute. I know my yellow side has red on her belly but she was 5 months old when I bought her so I haven't seen them when they were young

Maybe they're a new mutation... Yellow bellied conure

These babies have got a tiny bit of red on their bellies - they also have pink cheeks..

Their father has a pure yellow belly with no red whatsoever... He's also the largest green cheek I've seen... The babies take after him in looks and size.

Look like a very dilute yellow sided, but very cute, especially the first picture, love the expression, like "Yeah, look at my belly."
