Grey / Grey-green
A variant of Indian ringneck parakeet (Psittacula krameri)
Representative Indian ringneck parakeetphoto — a dedicated image of this exact morph isn't available yet.
The dominant 'grey' (Australian dominant) factor mutes structural color toward dove-grey; on a green bird it reads as grey-green, on blue as a pure slate grey. A dominant gene, so only one copy is needed to show it.
Keeper tips for this variant
Being dominant, grey passes to roughly half the offspring from a single grey parent — handy for breeders but watch you aren't doubling up cosmetic genes at the expense of vigor.
