Q: What is the
Christmas Bird Count?
A: A coast-to-coast annual bird census.
Volunteers count every bird and bird species over one
calendar day--from midnight to midnight. Over 45,000
people from all 50 states, every Canadian province, the
Caribbean, Central and South America and the Pacific
Islands (all the areas where the breeding birds of North
America spend their winters) participate in more than
1700 counts held during the two and a half week period.
A: Bird are indicators of the overall
health of our environment. Christmas Bird Count data over
time in any given area can provide insight into the
long-term health of bird populations and the environment.
Each bird count is a circle 15 miles in diameter --
approximately 177 square miles. Bird counters try to cover
as much of the circle as possible with a 24-hour calendar
day, counting each individual bird and species they see.
