Silver cuckoo-partridge
Color and pattern male
Plumage: basicly similar to silver-partridge but with cuckoo pattern, each feather dark-grey several times crosswise interrupted by a lighter-colored, slightly arched, bar which is not sharply defined.; males are allowed in either purebred or impurebred where the difference is that the appearance of the purebred is, because of wider lighter bars, clearly lighter than the female, the impurebred is similar to the female.
Head: silver-white.
Neck and saddle: hackles silver-white, each feather cuckoo with a middle-stripe, runs parallel to the outline, ends in a point near the tip, no high demands on the sharpness and the intensity; front of the neck similar to the breast; saddle-hackle has more or less distinct middle-stripe, absence is not considered a fault.
Back, shoulders and wing-bows: silver-white, some cuckoo pattern visible.
Wings: front and wing-bar dark blue-gray, crosswise interrupted by light blue-grey, slightly arched, bars.
Primary-flights: dark blue-gray, crosswise interrupted by light blue-grey, slightly arched, bars.
Secondary-flights: inner-web dark blue-gray crosswise interrupted by light blue-grey, slightly arched, bars; outer-web white, forming a wing-bay when the wing is closed.
Tail and breast: dark blue-gray, crosswise interrupted by light blue-grey, slightly arched, bars.
Thighs, belly and fluff: grey.
Serious faults
Complete off-colored feathers. Strong yellow or rusty brown in the ornamental feathers. White in tail and wing-flights. Too little cuckoo pattern in wings, tail and breast of impurebred.
Faults
A few off-colored feathers. Barring in the down.

Neck: hackle silver-white, each feather cuckoo with a middle-stripe, runs parallel to the outline, ends in a point near the tip, no high demands on the sharpness and the intensity; front of the neck similar to the breast.
Back, shoulders, wing-coverts, tail-coverts and saddle: each feather light-grey with dark-grey peppering several times crosswise interrupted by a greyish-white, slightly arched, bar without peppering, smooth shading between dark and light bars.
Primary-flights: dark-grey, several times crosswise interrupted by a slightly lighter bar, smooth shading between dark and light bars.
Secondary-flights: outer-web similar to the back, inner-web similar to the primary-flights.
