What kind of bird is the solitary bird?

The solitary duck is a waterfowl, one of several species of duck. They have larger bodies, weighing about 1 to 2 kilograms. The head of the solitary bird is black or dark brown, the feathers on the neck and chest are dark brown or black, and have a white collar; the belly and underwing coverts are white. The male solitary eagle's beak is long and narrow, gray or blue-gray in color, with special shapes and patterns, while the female solitary eagle's beak is relatively thick, short, and dull in color.

The solitary duck is mainly distributed in the temperate and sub-arctic regions of the northern hemisphere, including Europe, Asia and North America. They usually inhabit waters such as lakes, rivers and coasts, feeding on aquatic plants, small invertebrates, and occasionally small fish. The solitary pheasant is a relatively common wild bird that is also bred in captivity for poultry breeding or viewing.
