На приведенным мной фото - цветовая вариация обыкновенной кряквы.
Figure 1. Mallard/Pintail hybrid # 1 (Reifel Bird Sanctuary, Ladner, December 1992). This duck was closely associated with about 20 Mallards and the entire group dove, rather than dabbled. It was similar to a Pintail in its bill colour and head and neck shape, but had an intermediate neck length. It featured a variable head colour, partly iridescent green, partly dark brown; an incomplete, wide, T-shaped white collar (green nape); a medium brown breast grading to creamy belly and underparts; gray sides; gray-brown secondaries and wing coverts; gray primaries; a speculum greener than Mallard's; a two inch tail plume with upward curve; white and black tail feathers; a white rump; gray undertail coverts; and orange feet.
Figure 2. Mallard/Pintail hybrid # 2 (Stanley Park's Lost Lagoon, March 1993). This duck was associated loosely with Mallards and was similar to the one in Figure 1 except it had a slightly wider white collar with a more obvious upward arc, a thinner dark bill stripe, and a longer neck. A mangled white spot on its breast; missing white tail feathers, and a reduced black tail may have been due to mutilation.
Figure 3. Eurasian/American Wigeon (Jericho Park, March 1993). This duck was associated with American Wigeons and one Eurasian Wigeon. It exhibited a white stripe over the forehead and crown; a rust-coloured nape and hind neck; brown chin, throat, foreneck, and breast; gray collar; white wing patch; gray wing coverts and belly; white flank; and dark tail coverts.
Figure 4. "Bibbed" Mallard (Stanley Park's Lost Lagoon, December, 1992). This duck featured a white upper breast, chocolate brown underparts and lower breast, dark brown wings streaked with lighter brown, and no speculum. It may be a natural variant exhibiting partial albinism and melanism or a domestic/wild cross.
Figure 5. Probable Cayuga (Reifel Bird Sanctuary, March, 1993). This duck was mainly dark with a mix of brown, black, and green plumage, a white breast patch, black bill, some white on wing tips, reddish brown eyes, and a Mallard-like size and body shape. Earlier (December, 1992), at the same location, we photographed a similar duck (not shown) that had dark beetle-green plumage with a larger white breast patch, orange-brown legs, black bill with some greenish-yellow on upper bill, and dark eyes. These ducks are probably either domestic Cayugas or naturally occurring Mallard variants exhibiting melanism and partial albinism.
Figure 6. Blonde Mallard female (Jericho Park, December, 1992). Two different individuals were seen. Both were an overall pale, creamy colour. They are probably natural variants exhibiting leucism or possibly descendants of a white domestic strain and wild Mallards.
Figure 7. Ringless Mallard (Jericho Park, December, 1992). This duck lacked a white collar and dark brown breast. It is probably a natural variant.
Figure 8. "Reversed" Mallard in Basic Plumage (Jericho Park, December, 1992). This duck exhibited a general reversal of colour patterns on the body and breast (medium brown at back, light gray at front), a distorted white patch on the foreneck, no collar, and black-orange feet. It is possibly a natural variant or a domestic/wild cross.
Figure 9. "Reversed" Mallard in Eclipse Plumage (Jericho Park, July, 1993). This is the same duck as in Figure 8, photographed seven months later. Except for the gray wing tips and relatively normal brown speckled breast, this duck has become a uniform dark brown. The head has traces of iridescent green but is mostly dark brown to black.
