The grey currawong is found in wet and dry sclerophyll forests across its range, as well as mallee scrubland, and open areas such as parks or farmland near forested areas.
However, it can be encountered in mixed-species flocks with the pied currawong.
Less arboreal than the pied currawong, the grey currawong spends more time foraging on the ground.
The grey currawong builds a large shallow nest of thin sticks lined with grass and bark high in trees; generally eucalypts are chosen.
Less arboreal than the pied currawong, the black currawong spends more time foraging on the ground.
The clinking call resembles that of the superb lyrebird, which imitates the currawong call at times.
The eggs closely resemble those of the currawong hosts.
Within its range, the black currawong is generally sedentary, although populations at higher altitudes relocate to lower areas during the cooler months.
