This
is quite a large bird at approximately 42cm
The
male is bright red on the head and neck and underpants,
with bright green wings and back.
The
female has a green head, and red underneath. Both
have a light green shoulder stripe.
This
beautiful bird lives in moist, tall forests, in eastern Australia,
from Cooktown to Melbourne.
The
Australian King Parrots form into small flocks, and are very shy,
their flight is fast but erratic. They are rarely seen on the
ground, feeding in trees on berries, fruits, buds and seeds. 
The
nest is situated in tree hollows usually in tall eucalypts, these
being formed by broken limbs etc. All Australian parrots using
these sites as nests are in trouble due to the decline in nesting
sites. Frequent fires, land clearing, cutting down the old trees
all adds to the destruction of their nesting sites.
