It is that time of the year again, late summer, when the white cockatoos flocculate into a great seething mass of mayhem, bringing calamity to our neighbourhood. The corellas are here all year round but it is in the summer, after breeding, when then they get together for the “summer holidays”. I know some people don’t like them much as the marauding mass can be quite destructive. In some parts of Australia the sulphur crested cockatoos are a real menace, chewing great shards of wood from houses, sometimes chewing the window frames until the windows fall out! Light fittings, electrical cables and outdoor furniture can also be targeted.
