Bluebonnet
FAMILY: Psittacidae
GENUS: Northiella
SPECIES: haematogaster
OTHER NAMES: Bulloak Parrot, Red-bellied Bluebonnet, Yellow-vented
Bluebonnet, Naretha Parrot, Little Bluebonnet, Red-vented Bluebonnet, Pallid
Bluebonnet.
Description:
Medium sized gregarious
parrot which forms permanent pairs but oftren congregates in small social or
feeding flocks of up to 30 individuals. Male's forehead and face and cheeks
dark blue, breast and upper parts grey- brown. Abdomen yellow with red patch in
centre. Wings olive, glue on the bend of the wing. Flight feathers black, edged
with blue. Rump olive-brown. Central tail feathers bronze-green, outer tail
feathers dark blue with white tips.
The female resembles the male, but has a dull olive-green crown and a light
stripe underneath the wings. Immature birds resemble adults but are duller in
colour overall and have less red on the underbelly then do the adults (this is
true for all races). Fledgelings have a yellow beak and gain their adult
plumage at the first post-fledging moult (3-4 months of age).
The Bluebonnet is mostly terrestrial in its foraging habits, but roosts and
shelters in trees. It drinks mainly at dawn and dusk.
Length: 280-340mm.
Subspecies:
There are three other
rather distinct forms of the Blue Bonnet. although not formally recognised as
distinct species, these birds are regarded as a distinct species by some
authorities and many aviculturalists. They include:N. h. narethae
(Naretha Bluebonnet) a population which occupies the Nullarbor Plain, are
distinctly smaller than birds in the east and differ distinctly in plumage
details (A); N. h. haematorrhous (Red-vented Bluebonnet) occurs through
norther inland NSW to the southern inland plains of Qld. (B); and N. h.
pallescens (Pallid Bluebonnet) which is confined to the Lake Eyre basin
(C). 
Distribution:
Eratically distributed
across much of interior south-eastern and southern Australia.
Habitat:
Arid and semiarid scrub
and cropland, mulga scrub, mallee and dry open woodland.
Diet:
Seeds of various
(native) grasses and herbaceous plants, but also nectar, flowers and fruit.
Breeding:
Is strongly influenced
by rainfall and food availability, but generally peaks between August and
January.
The usual nesting site is a very small tree cavity, often close to the ground,
lined with whoodchip and rotten wood dust. The hen incubates the eggs but is
attended by the male who also contributes to rearing the young.
Courtship Display:
Males display by drawing
their bodies to their full height and opening and vibrating their wings and
fanning and shaking their tail feathers in a side to side motion. In addition,
they raise thier vestigal crest (feathers on the forehead) and bob the head.
This is usually followed by courtship feeding.
Unlike many other parrots, Bluebonnets do not engage in mutual preening at any
time.
Sexual Maturity:
These birds mature at
9-12 months of age.
Clutch:
4-7 rounded white eggs
(23mm x 19mm). Incubation period: 22 days. The young usually fledge at around
30 days.
Mutations and Hybrids:
Mutations for this
species have been recorded for the nominate form. These include: Cinnamon,
Lutino (sex-linked), Yellow (sighting), Pied, Dilute (recessive).
Hybrids have been bred with this species and the Eastern Rosella, Pale-headed
Rosella, Mulga Parrot, Hooded Parrot and the Naretha Bluebonnet.
Suitable Aviaries and Compatible Birds
As a minimum, a single
bird could be housed in a small cage provided it measures around 600mm x 600mm
x 800mm (approximately). However these parrots usually perform better in
aviaries. These need be no larger than around 1.5m wide x 3m long x 1.8m high
and lined with a light to medium grade mesh. In addition, the aviary should
offer plenty of shelter with part of the roof covered in and the back and sides
at least partially covered.
Species Specific Problems
Bluebonnets are mostly
terrestrial and intestinal worms are a common problem in species which spend
considerable time on the ground. Similarly, fungal infections may become a
problem. These are relatively easily dealt with however simply by maintaining a
high standard of hygiene
