Star
Finch
FAMILY:
Estrildidae
GENUS: Neochema
SPECIES: ruficauda
OTHER
NAMES: Red-faced Finch, Red-faced Firetail,
Red-tailed Finch, Rufous- tailed Finch, Ruficauda Finch.
Description:
Medium
finch with striking plumage.
Upper parts olive-yellow and underparts yellowish. Breast
olive grey with white spots. Front half of head crimson. Face and chin
crimson with white spots. Beak crimson, legs and feet
yellow, eyes red-olive.
Females resemble males but are generally
duller and have less crimson on the face. Immature birds are olive brown above
and pale olive below. The head and face are grey.
The Star Finch is usually
encountered in small wandering groups when not breeding. They feed mostly near
the ground, preferring to cling to the seedheads of
grasses rather than land on the ground. Pairs form very strong bonds and remain
in close contact.
Length:
110-120mm.
Subspecies:
No
formally recognised subspecies. Aviculturalists recognise two
subspecies: namely N. r. ruficauda (nominate)
and N.r. clarescens. The latter is found across northern and
north-western Austrlia and differs from the nominate
form in that the red colouration is significanlty
more extensive and brighter. Most of the specimens held in aviaries are of the
sub-species.
Status:
In
the wild - questionable
- probably endangered In aviculture -
Distribution:
Formerly
across northern Australia from Shark Bay to Northern NSW.
Today it is reliably reported from west of the Gulf of Carpentaria.
Habitat:
Riparian
vegetation in termperate to tropical swamps and
woodland.
Diet:
Ripe
and half ripe grass seeds.
At the commencement of the breeding season insects (esp. flying termites)
predominate.
Breeding:
Generally
March-April.
The nest is usually located in a bush or shrub up to several metres
above ground. The nest is globular about 150mm in diameter and lacks an entrance
tunnel. It is constructed from dead grass and lined with feathers.
The
selection of a nest site involves an elaborate ceremony. Both sexes sit on the
site of the future nest and simultaneously bow deeply with tails twisted. This
is followed by pivoting around the perch. Both the parents incubate the eggs and
rear the young.
In
captivity Star Finches prefer to nest in bundles of brush rather than other
receptacles. Because they like to nest close to the ground, and preferably in a
grass tussock, it would be advantageous to provide these (or some sort of artifical substitute) for nesting. To avoid problems with
exposure, Star Finches should be encouraged to nest in a sheltered section of
the aviary.
Star Finches require plenty of half-ripe seed heads, sprouted
seeds and live food to be encouraged to nest.
Courtship
Display:
Like
the crimson Finch, the Star Finch perorms a song and
dance whilst holding a grass stem (or similar token) in his bill. The feathers
on the head breast and flanks are ruffed and the tail twisted toward the female.
This is accompanied by a great deal of bobbing.
Sexual
Maturity:
Maturity
is attained at about 12 months, but these birds are most productive after their
second year and continue to be so until about their fifth
year.
Clutch:
3-6
pure white eggs (15mm x 11mm). Incubation period: 12-14 days. The young usually
fledge at around 15-17 days. Fledged birds should not be removed from the
parents until at least 4 weeks after fledging.
In captivity, Star Finches may
produce as many as three broods per year.
Mutations
and Hybrids:
This
species is known to have produced hybrids with the Red-cheeked Cordon-bleu and Red-billed Firefinch.
Hybrids with the Zebra and Crimson Finches have also been reported.
Mutations
include Yellow, Fawn, Cinnamon and Pied.
Suitable
Aviaries and Compatible Birds
For
breeding purposes Star Finches will be quite happy in suspended cages or
breeding cabinets. These should have at least the following dimensions: 700mm(long) x 400mm x 400mm. These birds are at their best
in larger planted aviaries. Such an aviary should provde plenty of shelter and should probably have a roof
over at least half its area. It shoud be noted
however that large numbers of these birds will destroy most aviary plants.
Star finches will readily share an aviary with most other small seed eaters
(eg. zebra, painted, parrot, etc etc)
including doves and quail. During the breeding season they may become somewhat
pugnacious but their disposition is satisfactory overall.
