Launched in 2002 by the Cornell Lab of Ornithology and the National Audubon Society, Ebird is a real-time, online checklist program that is free and easy to use. Their goal is to record as much bird data as possible by both recreational and professional bird watchers.
It seems to be working. In 2006, participants reported more than 4.3 million bird observations across North America. Hopefully, Ebird will continue to grow.
We want to encourage EVERYONE to join this online program. It is a great way to track all of your birdlists, from daily lists to life lists. One of the neatest features is the use of graphs that show abundance based on what data is recorded. Hence, the more people the more correct these graphs will be.
