Visual difference b/w ringneck mutations

[Sherjil]

I would like to ask the experts about how to visually differentiate between DD green (also called olive) and grey(sf or df) green mutations of rose ringed parakeet.

Appreciate if you can explain with the help of pictures or both male female in these mutations. Thanks

Olive

Inheritance: Incomplete dominant.

Description

Body: General olive; manifestation of Double Darkfactor in Green.
Tail: Dark bluegreen with yellowish tip.
Head: Olive, brighter around the beak; neck ring black with darkrose in cocks.
Beak/Feet: Red upper mandible, black lower mandible; grey feet, grey nails.
Eyes: Black with yellowish iris.

Note: Darkgreen has a single darkfactor; Olive has a double darkfactor. The tail and flight feathers are olive with dark blue tinge which differs from the Greygreen. Greygreens have dark grey, almost black, tail and flight feathers.




Greygreen

Inheritance: Dominant.

Description

Body: General greygreen; manifestation of Grey in the Green-series.
Tail: Dark grey with yellowish tip.
Head: Greygreen, brighter around the beak; neck ring black with rose in cocks.
Beak/Feet: Red upper mandible, black lower mandible; grey feet, black nails.

Note: Sometimes greygreen is erroneously referred to as olive. Olive is actually used for double darkfactored birds in the green-series.
