A swan hybrid refers to the offspring resulting from the interbreeding of different species or subspecies of swans. It occurs when individuals from two distinct swan species or subspecies mate and produce hybrid offspring. These hybrids exhibit a mix of characteristics inherited from their parent species, often displaying a blend of physical traits, plumage colors, and behavioral patterns. Swan hybrids can occur in both natural and captive environments, although interbreeding between different swan species is generally rare in the wild.
