Black-throated Finch
FAMILY: Estreldidae
GENUS: Poephila
SPECIES: cincta
OTHER NAMES: Banded Grass Finch, Black-rumped
Finch, Black-rumped Grass Finch, Black Throat, Parson
Finch, Diggle's Finch.
Description:
Medium to large grassfinch which resembles the Long-tailed Finch closely. Males have blue-grey heads with a blue-white
ear patch. Throat and upper breast is black. Flanks, belly and lower breast
light brown, back fawn- brown. Black bar on rump, black patch
between eye and bill. Bill is black , legs
orange-red.
Females resemble males, but are identified by having a comparatively smaller
throat patch. Immature birds resemble adults but have duller plumage still.
Length: 100mm.
Subspecies:
Aviculturalists recognise a form
found in northern Cape York Peninsula (P.c. nigrotecta) and is often referred to as the Chocolate
Parson Finch or Chocolate Diggle's Finch. The
essential difference between this and the nominate form is that it is darker
brown in colour overall.
Distribution:
North-eastern Australia
from Cape York southwards to northern New South Wales. Diggles
occurs north of Cairns-Normanton (QLD).
Habitat:
Undergrowth in tropical
and warm temperate savannah woodland - rarely far from water.
Diet:
Ripe and half-ripe seeds
of grasses, substituted with small insects, ants and spiders.
In captivity, a good quality finch seed mix should be the mainstay of the diet.
This should be supplemented with greenfood (eg half ripened seed heads of grasses or most other herbs
from the garden such as Shepherd's Purse, Dandelion and Chickweed, or any
vegetables such as silverbeet, lettuce, etc.).
Many aviculturalists provide live food (often
mealworms) during the breeding season although others have had good results
without it. Lastly, it is important to provide birds with ample grit (fine) and
perhaps cuttle-fish where possible.
Breeding:
All year round, but
mainly autumn in the north and spring in the south.
The nest is woven of dead grass and is flask-shaped (250mm long x 140mm high
and 110mm wide). Usually placed in eucalypt twigs, but also hollows
, termite mounds and even foundations of hawk nests.
Both sexes participate in construction of the nest and in the incubation of the
eggs. At night, both birds may share the nest.
In captivity
Black-throated Finches will accept a variety of nesting receptacles. For
convenience and cost reduction it is probably best to provide them with woven
cane baskets. Good pairs may produce as many as four broods a year.
Courtship Display:
Males approach females
with a series of bobbing movements. The feathers on the head and chest are
often ruffed. Females may also bob to some extent.
Sexual Maturity:
Most birds do not breed
until second year.
Clutch:
4-5 white eggs (18-7mm x
12mm). Incubation period: 14
days. The young usually fledge at around 21 days.
Mutations and Hybrids:
There are several known
mutations for this species: The chocolate form is a naturally occurring
mutation. In captivity, the following colour
mutations occur: Pied, White, Cream and Fawn.
Black-throated Finches are known to have hybridised
with the Zebra Finch, Double-barred Finch, Masked Finch, Long-tailed Finch,Spice Finch, Cut- throat
Finch, Red-headed Parrot-finch, Bengalese Finch and White-headed Munia.
Suitable Aviaries and Compatible Birds
For breeding purposes
Black-throated 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.
Black-throated finches will readily share an aviary with most other finches (eg. zebra, painted, parrot, etc etc),
quail, doves and even neophema parrots.
Species Specific Problems
This species tends to be
prone to infestation with endoparasites such as
intestinal worms, and to Cocidiosis.
