Help protect NSW’s wildlife this migration season.
Each year, short-tailed shearwaters (mutton-birds) travel thousands of kilometres from the northern Pacific to breed in south-eastern Australia.
During this migration, some birds may become exhausted and die from the stresses of the journey. Large numbers of dead shearwaters, known as 'wrecks', can be a natural part of migration.
While some seasonal mortality is expected, ongoing surveillance remains important following recent detections of H5 bird flu in wild birds in Australia.
Public reporting is a critical part of surveillance efforts and supports early detection and response activities.
As migratory seabirds return to our coastline, stay vigilant and report any sick or dead wild birds or wildlife.
If you see sick or dead birds or wildlife:
✅ Avoid contact
✅ Record what you see
✅Report sick or dead birds or other animals to the Emergency Animal Disease Hotline on 1800 675 888
