Behaviour
The Long Tailed Finch inhabits open woodland across northern Australia, from Derby east to the Leichhardt River in northern Queensland.
Male Long Tailed Finches approach unfamiliar members of the species and engage in a courtship display, holding themselves in an upright posture and singing, before attempting to mate with the newcomer. Male newcomers will sometimes not declare their sex when confronted by a group of birds. The authors of the study propose this is a survival mechanism to reduce harassment, increase chances of acceptance into the group and hence chances of future reproduction.
The species breeds in natural hollows. Pairs share feeding responsibilities, and there has been one report of birds from older broods helping their parents raise the following brood, the first time that cooperative breeding has been recorded in an Australian estrildid finch. The clutch consists of four to six dull white oval eggs measuring 17 x 12 mm. The incubation period is 13 to 17 days.

Famous quotes containing the word behaviour:
“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”
—Aldous Huxley (1894–1963)
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
