I haven't seen western corellas this close to Perth. They were probably
little corellas. The grubby bird probably had psittacine circovirus
disease. The Cacatua spp. will dig for food and the females will get dirty
when they are preparing a hollow, but usually it is only their faces which
get dirty and the powder down in their plumage soon cleans these areas
during preening. In most areas of Perth the main "soil" type is very sandy
and less likely to cause dirty feathers.
