Distribution / Range
The Blue Bonnet or Yellow-vented Blue-bonnet Parrot (Northiella haematogaster haemetogaster or Psephotus haematogaster haematogaster) is endemic to western and southern New South Wales, north-western Victoria and south-eastern South Australia
Blue Bonnet parrots are sporadically dispersed, socially gathering in groups of up to 30 birds.
Breeding / Mating
They permanently mate. Their courtship ritual is quite entertaining and entails fanning and shaking of their tail feathers, raising their crown feathers and a lot of head bobbing.
They nest in low-lying tree openings lined with wood substances. The average nest consists of 4 to 7 eggs, which are incubated by the female for about 22 days.
The male assists in rearing the young and feeds the female on the nest.
