11 Reasons the Christmas Bird Count Rocks

The world’s longest-running citizen science project is a boon for bird conservation.

From the Arctic Circle to the mountain valleys of the Andes, tens of thousands of people are gearing up to take part in the world’s longest-running citizen science project: the Christmas Bird Count. Birders of all levels will brave the elements to count birds during a three-week period, from December 14 through January 5. Want to take part? Registration is free and participants can easily sign up online.
