This species has the ability to mimic clearly and, like other cockatoos, bonds strongly to its owner. The western corella may show aggression to other birds in the aviary. It is not as common in aviculture as the little corella or long-billed corella.
While generally uncommon, it has expanded its range in recent decades, and is therefore listed as of least concern by BirdLife International. However, the nominate subspecies, Muir's corella, is relatively rare, with a population of around 3000 individuals, and is considered to be nationally Vulnerable.
