The galah is native to Australia, where it can be found in open grasslands and over much of the country. It has self-established in Tasmania. Galah cockatoos travel in large flocks, often in groups that also include sulfur-crested cockatoos. They will mate with other species of cockatoos. Galahs are a familiar sight in urban areas. These birds tend to be more prevalent in settled areas because they eat cultivated crops and make use of artificial ponds and livestock watering troughs. Many farmers regard the birds as pests. The name "galah" means "fool" or "clown" in the native Australian language Yuwaalaraay. This highly intelligent bird got the name for being a loud nuisance. The term "galah" is a slang, derogatory word in Australia that means a "loud-mouthed idiot."
