  • S7589 - Generally very few reported, at most a few hundred in aggregations and total likely remains under 1,000 birds; occasional influxes, possibly from E Australia, after local flooding in SW Australia coinciding with severe drought in E Australia. Breeding in SW Australia at least until early 1990s at wooded coastal and inland wetlands, many of which have since been lost or degraded.
