Australian Ringneck Parrots
by Mark Holmes, Angaston, S.A.
The ringneck family of
Australian parrots belong to the genus, Barnardius. They are
also referred to as Broad-tailed parrots. The ringneck group are
widespread throughout the drier areas of Australia and there are
four main subspecies recognised, namely :
Twenty-eight parrot
Port Lincoln parrot
Mallee ringneck
Cloncurry parrot
A hybrid subspecies
between the Port Lincoln and Twenty-eight parrot, the so-called
wheatbelt hybrid or the yellow-fronted Twenty-eight parrot, also
exists. All are widely kept in avicultural collections and are a
worthwhile addition to any fanciers collection.
The Twenty-eight and Port
Lincoln parrots and the wheatbelt hybrid are all very similar in
coloration and I am sure there has been many a friendly argument on
an aviary visit amongst aviculturists as to which is which.
In the Twenty-eight
parrot, the sexes are alike in body colouration. It is a large bird,
being approximately 40cm in length, of which 20cm is tail. The male
however, is slightly larger than the female and has a broader head.
Its head is dull black; lower ear coverts violet blue; it has a
narrow yellow collar around the nape; the back and wings are bright
green; the outer webs of the primary feathers are dark blue; the
throat and breast are dark green; the belly is green; the underwing
coverts are blue; the eye is brown; bill is pale grey; legs and feet
are grey. Both sexes have a red frontal band across the top of
the bill, as do the wheatbelt hybrids. The wheatbelt or
yellow-fronted Twenty-eights as they are often called have the same
colourings and markings, except the belly is yellow grading to a
pale green towards the vent.
Immatures of both the
Twenty-eight and the wheatbelt hybrid are duller than the adults
with a brown hue about the head. The Twenty-eight has a tri-syllabic
call, sounding like 'twenty-eight', as the last note is higher in
pitch than the first two. This call has given rise to their common
name.
The Port Lincoln parrot
is also known as Bauer's parrakeet, Banded parrot or the Yellow-naped
parrot, although these names are not widely used.
Once again the sexes are
similar with the male being slightly larger with a broader head.
They are 37cm in length, including 19cm of tail. The head is dull
black; lower ear coverts are violet-blue; narrow yellow collar on
the neck; back and wings are green; outer web of primary feathers
are green, becoming blue towards the tips; the lateral feathers are
blue edged with pale blue; the throat and breast are blue green and
the belly yellow changing to a yellow green as nears the vent and
undertail coverts. Underwing coverts are blue; the eye is brown;
the bill pale grey and the legs and feet are grey. Neither the male
or female Port Lincoln has a red frontal band although some
individual birds may have a small red spot above the bill. This is
due to interbreeding, as the Twenty-eight, the wheatbelts and the
Port Lincoln will readily hybridise. This is most noticeable in
large numbers of trapped birds that dealers have on hand at times.
Immature Port Lincoln's
are once again duller than the adults with the head having a brown
hue.
The contact call is a
high pitched whistling note, repeated rapidly several times. The
alarm call is harsh and metallic, being very similar to that of the
Mallee ringneck.
The Twenty-eight and Port
Lincoln breed from August to February, mainly in central and
southern Australia. Birds in northern Australia are known to start
nesting as early as June, but this often depends on the rainfall.
They often double brood in the wild although I have rarely heard of
them double brooding in captivity.
There is a great activity
at the start of the breeding season as the pair inspect every hole
and hollow in the branches of a living or dead eucalyptus tree,
chattering incessantly and wagging their tails. Once a breeding
pair have selected a hollow they defend it vigorously against other
parrots.
During the mating
display, the courting male crouches in front of the female, squares
his shoulders and wings and vibrates them slightly, with his tail
fanned and moving quickly from side to side. While doing this he
chatters constantly.
They nest in a hollow
limb of a eucalyptus tree, laying four to seven (usually four),
rounded, white eggs 31x25mm in size. The bottom of the hollow is
lined with wood dust as a soft bed for the eggs. Hens sit for 21
days and young fly after 30 days.
The Port Lincoln is
widely distributed on the west coast of South Australia around
Kimba, north to Alice Springs, west from Alice Springs to the
Western Australian coast, and the whole of WA below that line,
except the south-west corner. They are most common in most types of
lightly timbered country, from eucalypt woodland to mallee and
dry acacia scrubland of the central regions.
The Twenty-eight inhabits
dense eucalyptus forests in the south-west of Western Australia.
Twenty-eights and Port
Lincolns feed on the ground or among the branches of trees and
shrubs, eating a variety of seeds and plant food.
These conspicuous birds
are noisy and inquisitive. When disturbed they fly to a nearby tree,
call excitedly and evaluate the danger before flying away. The alarm
calls given by one bird quickly attracts others and soon the
disturbance, be it a snake, goanna or other, is being investigated
by a dozen or more chattering parrots.
Twenty-eights and Port
Lincolns in an aviary have been known to be very aggressive towards
their young when they have fledged and it is best to isolate the
young as soon as they are independent. They have also been known to
continually chase their young from the feed bowl, resulting in the
death of the young birds.
The Mallee ringneck
parrot is also known as the Mallee parrot, Ringneck parrot,
Barnard's parrakeet or buln buln. It is often confused with its
close relative, the Cloncurry parrot. Both the Mallee ringneck and
the Cloncurry are the same size but their body colourings are
different and more distinct than the Twenty-eight and Port Lincoln.
They are approximately
34cm in length including 17.5cm of tail.
The male Mallee
ringneck has an overall blue-green body plumage, a red frontal band
above the beak and blue cheeks. They have a V-shaped brown-blue band
extending from the eyes, back around the head, to meet a narrow
yellow collar at the nape. There is an irregular band of
orange-yellow across the belly, with the back and mantle a deep
blue-black. The shoulders are yellow; the outer webs of the flight
feathers blue, the underwing coverts also blue. The central tail
feathers are blue with a faint edging of white. The eye is dark
brown; bill is pale grey; feet and legs are grey.
The female is very
similar to the male, but the back and mantle are a dark grey-green.
The hen is slightly smaller, especially in its head size.
Immature birds are duller than the female. The normal call sounds
something like 'Kwink-Kwink-Kwink' and, when disturbed, the alarm
call is a harsh metallic shriek.
If feeding in branches or
shrubs, they will utter a subdued chattering.
Mallees blend extremely
well with their surroundings, either when feeding among the outer
branches of eucalyptus or mallee or on the ground.
Their diet consists
mainly of the seeds of grasses and herbs, fruit, blossoms, leaf buds
and insects and their larvae, They are usually seen in pairs or
family groups.
The breeding season is
usually August to January, but may be triggered by heavy rain. After
choosing a hollow, the pair spend considerable time preparing it,
lining the bottom of the hollow with decaying wood dust and making a
shallow depression for the eggs.
The courting male
crouches in front of the female, squares his shoulders and wings
and vibrates them slightly, with his tail fanned and moving quickly
from side to side. He also chatters constantly.
Four to six white eggs
are laid (usually five); they are rounded and are 29x23mm in size.
The female incubates the eggs for 20-21 days and the young leave the
hollow after about 30 days.
While the female feeds in
the early morning and late afternoon, the male sits in a nearby tree
and warns of approaching danger.
The Mallee ringneck is
common in mallee scrub, open woodlands
and in trees along
watercourses and is distributed from the Murray Flats and Murray
Mallee of South Australia, to the sunset country of north-west
Victoria and western NSW. They are also seen in southern Queensland.
When seen in an aviary,
their colouring may seem a bit ‘ordinary’, but when seen in the wild
they are very impressive.
Soon after sunrise they
leave their roosting perches, drink and move out to the feeding
areas until mid morning. During the hottest part of the day they
shelter in the trees or forage in the shade for seeds, fallen fruit
and the like. Towards dusk they become active and feed and drink
before roosting for the night.
The Cloncurry parrot is
often confused with the Mallee ringneck in captivity. In the wild
the Cloncurry parrot is restricted to the Selwyn Ranges in
north-west Queensland.
The Cloncurry is of
similar size and stature as the Mallee with the sexes alike. The
Cloncurry has a general plumage of pale green; no red frontal
band; a wide pale yellow band across the belly; the wing coverts are
green; and the tail feathers get darker as they go down the tail,
almost to a blue. The feet and legs are grey-brown. The female is
paler than the male and slightly smaller. Immatures are duller than
the adult birds and may posses a russet frontal band which
disappears after a few months.
They have a call,
courtship and mating habits very similar to a Mallee. They seem to
be a quieter bird and more docile among my collection of
ringnecks. The male Cloncurry is the clown of my collection, as he
usually hangs upside down on the
aviary roof and moves from one side to the other. He is usually seen
to roost this way too.
As far as feeding is concerned,
ringnecks like a diet of small parrot mix comprising, for example,
plain canary seed, grey sunflower (not black), hulled oats, pannicum,
white millet and safflower.
They also relish a regular supply of
fresh apple, silver beet, orange quarters, carrot, seeding grass,
wheat, barley grass, millet sprays and sunflower heads. Be careful
with grass from the roadside as it may have been sprayed by the
local Council.
They also enjoy almonds
and nuts. Do not feed almonds that have been left to get damp. Make
sure they are stored in a dry place and cracked when needed.
The floor of the aviary
should consist of a sand or grit base, and cuttlebone and shellgrit
should always be available. They also enjoy a fresh branch of mallee
or other gum in the aviary every so often, chewing off the leaves
and climbing all over it.
In all, I have found my
collection of eight pairs of ringnecks, comprising three pairs of
Port Lincolns, two pairs of Mallees, and one pair each of the
Twenty-eight, wheatbelt hybrid and Cloncurry, a rewarding addition
to my aviaries. One pair of Port Lincoln's are laying, and another
is working their hollow, as is the pair of Mallees and the
Cloncurry. Most of my ringnecks are only 12 months old, so I am not
over hopeful of achieving success just yet.
Some of mine are housed
in adjoining aviaries, with heavy gauge 13mm mesh. I hope to have
them in every second cage by next season as I build some more cages.
My aviaries are all 2.4m deep, 0.9m wide and 2.1m high, except two
which are 3.7m deep, 1.1m wide and 2.1m high. Their hollows are all
60-90cm long and hung at 45° angle, away from the afternoon sun.
