Juveniles have entirely black plumage; orange-red feathers first appear on their breast and throat, later spreading to the neck, head, and thighs.
The back and sides are gray, the belly is white and the rump and tail are black. Male bills are pale blue with a black tip and a thin ring separating the two colors. Non-breeding males lose the copper color and instead have brown heads. The eyes are yellow, one of the most obvious distinctions from canvasback and common pochard, which have red ...

[10] Their heads may be red, black, or yellow.
It often nests in colonies, some being quite large. Bird houses are also a suitable nesting site. Four to seven eggs are in a clutch. This bird is a permanent resident in much of its range. Northern birds migrate in flocks to the Southeastern United States. The distribution of the common grackle is largely explained by annual mean temperature ...
