WHAT IS EBIRD?
eBird is the world’s largest biodiversity-related citizen science project, with more than 100 million bird sightings contributed each year by eBirders around the world. A collaborative enterprise with hundreds of partner organizations, thousands of regional experts, and hundreds of thousands of users, eBird is managed by the Cornell Lab of Ornithology.
eBird data document bird distribution, abundance, habitat use, and trends through checklist data collected within a simple, scientific framework. Birders enter when, where, and how they went birding, and then fill out a checklist of all the birds seen and heard during the outing. eBird’s free mobile app allows offline data collection anywhere in the world, and the website provides many ways to explore and summarize your data and other observations from the global eBird community.
EBIRDING ON A CBC
While doing your CBC, eBird Mobile makes it easy to keep your tallies through the day. Here are our tips for making your CBC eBirding as helpful as possible.
- Only submit lists that include birds observed by your CBC group: do not group lists from other birding parties together
- Keep multiple lists throughout the day: ideally one for each stop, or perhaps one for each road.
- Include only one-way distance in your traveling counts: both CBC and eBird measure distance as one-way distance
