December 2021 | Ornithology

On December 25, 1900, ornithologist Frank M. Chapman of the Audubon Society began a "Christmas Bird Census" (CBC) to encourage people to count birds during the holidays rather than compete in a traditional “Side Hunt.” The CBC is an example of the rise in awareness, led by early conservationists, of the impact humans were having on wildlife. This tradition continues with the Audubon Christmas Bird Count held every year from December 14th to January 5th. Over the last 120 years, data collected from this count, and other bird surveys across the globe, have been helpful in understanding the health of bird populations. Today, the research conducted by ornithologists across the field is critical to protecting birds and their habitats.
