Similar Species
Looks somewhat similar to, but has no family relationship with, the other two Choughs (Red-billed Chough and Yellow-billed Chough).
Distribution
East and south Australia.
Widespread but not common.
Taxonomy
Two subspecies are recognized:
- C. m. melanorhamphos in eastern Australia (from eastern half of Queensland south to New South Wales, Victoria and southeast South Australia)
- C. m. whiteae in south and southeast Australia (Eyre Peninsula and Mt Lofty Ranges)
There are only slight differences in these two subspecies and whiteae is not always accepted. The different authorities also don't agree on the spelling of melanorhamphos / melanoramphos.
Habitat
Dry woodland and mallee. Also found in plantations of exotic pines, well-wooded farmland and suburban areas with parks and large gardens.
Behaviour
Feeds on a wide range of insects and seeds. Forages mainly on the ground in big groups, digging with its bill and turning over and raking through leaf litter.
Has been recorded chasing mice from under grass tussocks, grabbing them by the neck and beating them against the ground before consuming them.
Breeding season in austral spring and early summer from September to December. A co-operative breeder with up to 18 helpers for a pair. The nest is a large bowl made of mud. It's placed 2.5 to 20m above the ground on a tree. Lays 3 - 5 eggs.
A sedentary species, wandering over a large home range outside breeding season.
