Apostlebird
Struthidea cinerea

Along with the White-winged Chough, the Apostlebird makes up the family of Australian mudenesters, the Corcoracidae. Their name comes from their gregarious nature, often moving around in parties of a dozen, hence the connection to the twelve apostles. Other names include happy families, happy jacks and grey jumpers. They are tame and curious by nature and can be well-habituated to scrounging food at campsites. They are found in the eastern of Australia, but generally west of the Great Dividing Range. They are fairly large birds at 29-33 cm.
