The Big Sit! is a free, annual, international birding event open to anyone, anywhere in the world. All individuals or groups are eligible to participate; just follow The Big Sit! rules and submit your results. The Big Sit! can be as competitive or non-competitive as you would like, but it is meant to be fun. Some people have called it “a tailgate party for birders.”
The Big Sit! is October 8th and 9th.. Participants can choose to do their Big Sit! on either Saturday or Sunday. The Big Sit! is like a Big Day or a Bird-a-thon. Individuals or teams find as many species as possible in 24 hours. There is one critical difference – all observations must be made from within a circle no more than 17 feet (5.2 meters) in diameter.
It’s fun. It’s a challenge. It’s a tradition for teams of birders who look forward to hanging out with old and new friends and finding birds. Many birding organizations make The Big Sit! a fundraiser, with sponsored teams or with donors pledging a certain amount per species. Whether you are new to birding or birding for years, The Big Sit! is a great tradition for you!
All data generated by the event is entered into eBird and can be accessed by the scientific community giving a snapshot of the bird Autumn Bird Migration .
