Feathers are one of the epidermal growths that form the distinctive outer covering, or plumage, on birds. They are the outstanding characteristic that distinguishes the Class Aves from all other living groups. Other Theropoda also had feathers.

American Christmas tree

American Christmas traditions range from religious symbols to the mythos of Santa Claus. Their origins are both Christian and pagan.

A Christmas song is a song which is normally sung during the time period leading up to, and sometimes shortly past, Christmas day, and usually has lyrical content addressing the holiday, the winter season, or both. These songs recognizably fall into several different groupings, depending on both the content and age of the songs.
