ive read this forum and learnt how budgies can see ultraviolet and thats why they have cheek patches that stand out during courtship etc.

some birds i have dont have as big patches on their cheeks or are half covered in white even they are lutino.. The question id like to ask is whether if a male budgie has more pronounced ultraviolet cheek patches, are they more likely to have a partner and breed and do you think a hen would prefer that cock then one without one or half covered??????

thanks

What we see of the cheek patches is not what budgies see. You are talking about semi white patches, normal patches, etc etc etc. We cant see in ultraviolet so you cant really say that a half white half blue patch is somehow less visually appealing on the ultraviolet spec.

 

There are other feathers seen on the ultraviolet spectrum as well and it would take a black light and a dark room to do some basic observations over time.
