Annual Sydney Olympic Park Spring Bird Census
The Spring Bird Survey is undertaken as a partnership between the Sydney Olympic Park Authority and the Cumberland Bird Observers Club. Each year between September and November, surveys of 46 quadrats are undertaken between 6am and 9am concurrently each week for eight weeks. The quadrats are representative of all habitat types and varying mixed-use zones in the Park from the highly urbanised town centre to remnant bushland. All quadrats are surveyed for 20 minutes.
