This calendar, often called a "Birthday Calendar," is specially created for remembering birthdays, anniversaries, and other events that occur on the same date every year. Designed to be used year after year, it will be convenient for recording other natural happenings such as flower bloom dates, frost dates, snowfalls, and the life histories of birds and other animals.

Natural events involving flora and fauna listed here are a compilation of years of recordkeeping by Todd Fink (1959-1995), an ornithologist and natural heritage biologist. In many instances they represent the peak occurrences of specific events, rather than precise forecasting, and should be used as guides or cues. Those familiar with the first edition of this calendar will discover dozens of new entries that Todd had been recording in anticipation of the second printing. Thanks to Judy DeNeal and Bob Lindsey, Todd's friends and colleagues, who gladly provided editing for much of the new information.

The designs are inspired by the many bird-like elements found in Native American arts. The mythological, ceremonial and representational subjects were inseparable parts of all objects created to satisfy the utilitarian and spiritual needs of the first Americans.
