The Christmas Bird Count begins. Time to count some birds
Before the 20th century, some North Americans organized ‘Christmas side hunts’ in which participants would choose sides, then compete to bag as many birds as possible. In 1900, ornithologist Frank Chapman suggested a bird census instead, and the Christmas Bird Count (CBC) was born. This year, the CBC runs from today through January 5, 2019, giving citizen scientists across North America time to join in, get outside, and spot some birds. The data collected is used to gauge the health of various bird populations–this information is then used to focus conservation efforts on particular species and geographical areas.
