The Blue-winged Parrot
By Gerry Solly
Distribution
The Blue-winged Parrot
(Neophema
chrysostoma) inhabits the
whole of Tasmania, the islands of Bass Strait, the whole of Victoria
and the South-eastern portion of South Australia. The northern
extreme of the range being roughly a line drawn from Gawler in South
Australia through Broken Hill in New South Wales to the Victoria-New
South Wales border on the east coast.
Description
The Blue-wing is approximately 200
to 225mm in length, which is about average for all the
Neophema
groups. The upper surface is olive
green, the underparts yellow, the wings are blue with black flight
feathers, the nose-band is blue.
Sexing
The Blue-wing is the hardest of all
the Neophemas to sex. As with the Elegant
(N. elegans)
the blue nose-band is the
surest method of sexing these birds. It is usually broader and
darker on male birds. However, it is possible to get bright females
and dull males which look identical. In this case I go by the black
of the flight feathers. In the case of the male these are an intense
glossy black, while those of the female are a duller grey-black.
Immatures
The young are a dull version of the
hen and take about six to nine months to attain full colour. It is
almost impossible to sex immature birds.
Breeding
Blue-wings nest later in the season
than the other
Neophemas.
They rarely go to nest
before mid-November and sometimes as late as mid-December. If a
pair double broods the second nest is seldom before late January.
As a consequence many young are lost in the nest due to the high
temperatures prevailing at this time - December and January
temperatures are usually in the 30-35 degree Celsius range.
Clutch sizes vary between four and
six eggs, the usual number being four or five, six being very rare.
Good birds in top condition usually have 100% fertility. It is
uncommon to find an infertile egg, unless the birds have been
inbred. The hen sits extremely tightly. It is often hard to get her
to leave the nest if you want to inspect the eggs. I have had to
lift hens off on many occasions when inspecting the nest. They do
not seem to mind this as they return to the nest as soon as the
aviary is vacated. The eggs take about twenty days to hatch. The
young spend three to four weeks in the log and take another two to
three weeks to become independent.
I have found that the Blue-wing is
the only
Neophema
to prefer logs hung at an angle. I
give all my parrots a choice of logs when they first go to nest, one
at an angle and one vertical. All the other
Neophema
species invariably choose a
vertical log, but I have only had one pair of Blue-wings do so.
Diet
As with the other
Neophema
species the staple diet consists of
canary seed, millet (white and Japanese), pannicum, hulled oats and
sunflower. They show a preference for the oats and sunflower. This
tends to make them fat, but as it does not appear to interfere with
their breeding capabilities or affect their life span I give these
seeds to them as they want them. They also consume large quantities
of seeding grasses in season and much silver beet and milk thistle
during the rest of the year. Large amounts of green-feed are
consumed when feeding young.
General
Blue-wings tend to be flighty birds
and go into mad panic if frightened. This seems to be a natural
quirk of this species, as I have found hand reared young very
friendly until released into an aviary, they then quickly become as
wild as those raised by the parents.
Except for Elegants, they get on
very well with birds in adjoining aviaries. I have housed them with
Bourkes
(N. bourkii) with quite good
results. This is probably because Bourkes go to nest as early as
September and the Blue-wings not until two months later, thus there
is no competition for logs.
Bathing is a favourite occupation.
As soon as I place fresh water in their dishes they are in it. They
also like to get under a fine spray from the hose.
I
offer my birds the following logs:
Vertical 450 to 500mm in length
with a 50mm hole 60mm from the top.
Angular 600 to 700mm in length
with a 50mm hole 60mm from the top. Both ends are closed and the log
hung at an angle of 25 to 30 degrees from the horizontal.
I use nesting material consisting
of 50% peat moss, 25% coarse sawdust (not shavings) and 25% sifted
dirt. This is mixed and left to stand for six to twelve months
before being compacted into the bottom of the logs.
