finch, owl-faced finch, banded finch, ringed finch, black-ringed finch;
French: Diamant de Bichenov; German: Ringelastrild; Spanish: Pinz? de
Dos Barras.
Distribution:
Australia in southeastern
New South Wales, Queensland (except the southwestern part), and northern
area of Northern Territory.
Description:
Male, crown, neck, shoulders, and further upperparts, gray-brown, with
very fine bars. Black wing-coverts with white dots. Tail black; rump
white. Forehead black; one black band across the throat and bordering
the cheeks; another black bar bordering the breast from shoulder to
shoulder. Throat, face and underparts white; the latter with a buff
sheen. Eyes dark brown, beak gray, legs dark gray-brown. The female's
breast is slightly paler; blackish gray wing coverts. This species is
the smallest of all Australian grassfinches Length: 3-4 in.
PHYSICAL CHARACTERISTICS:
3.9?4.3 in (10?11 cm). Sexes alike.
Adult Male:
General colour above, including crown of head, pale brown, with fine
barrings of dark brown, coarser towards rump; band across rump black,
remainder of rump and upper tail-coverts white; upper wings like back,
remainder of wings brownish-black, spotted white; tail-feathers black or
brownish-black; lores, feathers above eye, cheeks, ear-coverts, chin and
throat white, bordered with narrow black line, which widens on forehead
into a wide black band; fore-neck and chest white, slightly tinged in
centre, and washed with brown on sides of chest, followed by second
broad black cross-band; remainder of under-surface white washed faint
creamy-buff; under tail coverts black; bill bluish-grey; legs and feet
grey; eyes dark brown. Total length about 4 inches.
Adult Female:
Similar in plumage to male,
though black bands above and below white breast may be somewhat narrower
in female. As there is a big overlap of "male" and "female" characters,
sexing is very difficult and in many cases impossible.
Immature:
Duller in coloration, the barrings indistinct throughout and upper parts
tinged greyish-olive."
Habitat:
Inhabits dry, open areas including grass plains, open woodland, forest
edges, cane fields, inhabited and cultivated areas, and parks and
gardens.
Behavior:
Found in small flocks during the breeding season and in larger flocks
when not breeding. Roosts communally in specially built nests. The call
is a "tat, tat" or a "tiaat, tiaat." The song is a softer version of
that of the zebra finch.
Breeding:
Owl Finches usually lay 4 to 5 white eggs, and if you find more in the
nest the chances are good that you have paired together two females.
Incubation is 12 days, and both sexes take turns incubating the eggs
during the day, and both roost together on the eggs at night. When newly
hatched, Owl finches are a light flesh color, and they become darker
each day until they are almost black in color about the forth day. When
the babies finally emerge from the nest after about 22 days, they are
dull little copies of their parents. After the babies have left the
nest, I leave the babies in the cage or flight with the parents for
three or four weeks before removing them.
Owl finch babies are very small when they first hatch but they do grow
fast. You can usually band the babies at 7 or 8 days of age. When the
parents are rearing the babies, make sure that every day they receive
sprouted seed and egg food. I also make sure they receive "mini" meal
worms and wax worms every day after the babies hatch. When the babies
have fledged and I catch them up to remove, I will put on a plastic
colored band on the unbanned foot so that I can positively identify the
bird if I see it singing.
