The
Brown Quail - Coturnix australis
Other
names - Swamp Quail
Length
- 175-2OOmm (6.89-7.87 inches)
Adult weight
- 65-140 grams (females tend to be heavier).
Description
-
Cock - Upper parts dark brown
marked with black and chestnut1
each feather with a central white stripe. Chin and throat
light brown. Remainder of underparts lighter brown with black scalloping.
Upper breast darken Eyes red, brown or yellow. Bill black or dark
brown. Legs and feet yellowish.
- Hen - Similar to cock
but more heavily marked with black and with less chestnut on the
back.
Sexing
- Adults may be sexed
with relative ease by visual differences. Hens also tend to appear
somewhat larger than cocks. Difficulty exists when individuals or different
colour morphs are compared. Three colour morphs exist namely brown,
grey and red. All hens are of the brown morph but cocks may be of
either of three colour forms. Red morph cocks predominate in the
north and In arid areas. Grey morph cocks are rarer in Australia
but common In mainland New Guinea. This variation between cocks
will also affect the degree to which sexual dimorphism is shown
in an area. Juveniles will attain adult plumage at 10-12 weeks of
age.
Hatching
- The newly hatched chick
is golden brown with two dark stripes down the back and a thin chocolate
brown line running back from the corner of the eye. The depth of
colour of the newly hatched chicks may give some indication of sex
with the darker chicks usually being young cocks (and therefore
showing similar differences to adults).
Distribution
and Habitat - This species
is found in New Guinea, Australia, Lesser Sunda Islands, Fiji and
New Zealand (in the latter two it Is an introduced species). It
is generally resident but inland birds may be nomadic. Birds have
also been recorded as migrating from southern Papua New Guinea to
Northern Australia.
In the wild this species
occupies a variety of habitats ranging from Eucalypt woodlands to
rainforest. Its only requirements are that the area contains regions
of dense grass or herbage In moister areas. Riverbanks and roadsides
are popular and this is where they are commonly seen as they move
out into open areas to feed.
Subspecies
- Four Australian subspecies
are recognised. These are:
C. a. australis
- This Is the nominate form found throughout mainland Australia.
The cock of the brown morph Is as described above. Red and grey
morph cocks have a predominance of their appropriate colour replacing
part of the chestnut on the back and sides.
C. a. ysilophora - This
subspecies still causes some confusion. Also known as the Swamp
Quail, this subspecies Is considered larger, more clearly marked
and has a yellow Iris. It is generally documented as a form restricted
to Tasmania but recent studies have shown that individuals in the
mountainous areas of Papua New Guinea also show these characteristics.
C. a. queenslandlcus -
This is a subspecies recognised from the Cape York Peninsula, Queensland.
It is considered smaller than the nominate subspecies.
C. a. cervinus -
This subspecies is recognised from the Kimberley region, Western
Australia and is considered smaller, paler and redder than the nominate
subspecies.
Only the former two subspecies,
C. a australis and C. a. ysilophora are known to
exist In aviaries in their pure form.
Housing
- Although somewhat bulky,
this species is considered suitable for a mixed collection of finches,
softbills, pigeons and doves and small parrots. Only In large aviaries
greater than 10m2 (108
feet9 floor area, should this species be mixed with other quail
or colony bred as they can be particularly territorial. This can
also be a problem if housed with ground nesting pigeons such as
Squatter Pigeons. When I have had these species nesting together,
the Brown Quail tend to dominate and may drive the pigeons
off the nest. This
species looks most attractive when housed in a lightly planted aviary.
When introduced into an aviary, some individuals of this species
may be flighty and this will often result in scalped birds if measures
are not taken to avoid it. Prior to releasing your new purchase
into the aviary, it is wise to clip both the primary and secondary
feathers of one wing to restrict the power of flight. A cover or
plant growth, grass or dried brush will also reduce the nervous
tendencies of these birds. Unless the individual birds are known
to be quiet, it is generally unfair to the birds to expect them
to feel secure in open parrot-type aviaries. The call of this species
is generally unobtrusive but the mating call Of the cock can be
penetrating if two cocks are kept within earshot of each other and
continually point out their territories to each other. Occasionally
this species may call at night, but I am yet to associate this with
any greater risk of cat attacks as is often suggested.
Feeding
- In the wild, this species
forages in open areas and light undergrowth for seeds, insects and
greens. In the aviary, a commercial small seed mix (such as Finch,
Budgerigar or Small Parrot mix) is adequate for a maintenance diet
when supplemented with greenfeed. This species will tend to scratch
the seed out of shallow containers so seed is best supplied in a
deep l00mm (4 inches) container or in a shallow tray covered 50
(2 inch) plastic trellis mesh. White ants, mealworms or maggots
(gentles) should be fed daily during the breeding season. Other
foods that will be readily accepted by this species include coarse
laying mash, dotterel mix, and turkey starter crumbles.
Breeding
- Nesting may occur at
any time of the year, however August to May Is the peak breeding
season. Some pairs may be erratic in their breeding and several
successful nests may be followed by a period of inactivity.
Nests are built on the
ground usually in a secluded site against a grass clump or In a
corner under shelter The nest is little more than a scrape in the
ground lined with grasses pulled in from the immediate surroundings
of the nest area. Some pairs will unfortunately lay their eggs all
over the aviary floor. This generally can be related to a lack of
privacy and the provision of more grass clumps or tea-tree branches
placed in the corners may help.
