For the first time in eight years, the Double-barred Finch has been recorded at Sydney Olympic Park.

This fancy‑dressed feathered friend was once a regular sight in the Parklands; however, drought, heat event, habitat loss, and competitive exclusion from territorial species like the Noisy Miner caused numbers to decline to the point where they hadn’t been observed in the Park since 2018.

Challenges for woodland birds

Finches and other small woodland birds are particularly sensitive to changing environmental conditions, with the Millennium Drought (2001–2009) and the Tinderbox Drought (2017–2019) correlating with observed declines.

Another challenge facing small woodland birds like the Double-barred Finch is competitive exclusion from aggressive territorial species, particularly the Noisy Miner. Noisy Miners prefer open woodland with little to no understory vegetation and can congregate in large colonies. These colonies are highly territorial, often chasing smaller birds away from the area.
