Justification for EICAT assessment
The Long-billed Corella poses an environmental threat to Black cockatoos by out-competing for nest sites, their ability to remove eggs from the nest hollow and to kill and maim advanced nestling. There is no evidence that this has cause a decline of these species (Western Australia Museum, 2015).
