Some key facts from Cornell:
- The name "Bohemian" refers to the nomadic movements of winter flocks. It comes from the inhabitants of Bohemia, meaning those that live an unconventional lifestyle or like that of gypsies.
- The Bohemian Waxwing does not hold breeding territories, probably because the fruits it eats are abundant, but available only for short periods. One consequence of this non-territorial lifestyle is that it has no true song. It does not need one to defend a territory.
- Only three species of waxwings exist. The Bohemian and Japanese waxwings have white edges to the wing feathers, but the Cedar Waxwing does not. An unusual Cedar Waxwing was found with the ornate wing pattern, suggesting that the ancestor of all three species had a patterned wing.
