Mark your calendars for October Big Day 2021, sponsored by the Cornell Lab of Ornithology! Big Days are a 24-hour opportunity to celebrate birds near and far. Wherever you are on October 9, take a few minutes to submit observations and support conservation worldwide.
By taking part in October Big Day, you’ll also join the second-ever Global Bird Weekend and help celebrate World Migratory Bird Day. Be a part of the global team, and help set a new record for birding.
