The Barnardius genus include a single species - the Australian Ringneck - with several subspecies. As the name implies it is endemic to Australia. They are characterised by a yellow ring around the neck.
In captivity they have a tendency to becoming overweight so a low fat diet should be provided; sunflower seed should be avoided or kept to a minimum. A diet based on pellets supplemented with various fruit and vegetables is recommended.
They are not sensible to cold weather and can tolerate temperatures down to -4°C (25°F ) for short periods without problems.
