“…Displays have been described for a number of species of Ploceinae by Crook (1964) and Emlen (1957); sparrows of the genus Passer were reviewed by Andrew (1961); and the waxbills and grass finches of the family Estrilididae are well known from the work of Moynihan and Hall (1954), Morris (1958), Kunkel (1959), Harrison (19626), Immelmann (1962ft), and Immelmann et al (1965). -A brief comparison of the displays of the indigobirds and other viduines with the displays of other Old World finches and sparrows may be helpful in suggesting the possible origin of these behavior patterns from the behavior of the non-parasitic relatives and their adaptive modification in the indigobirds.…”

“…Cordon-bleus (i.e. species of the genus Uraeginthus ) rarely produce undirected song in the presence of the mate, but rather when they are separated from the mate, and therefore their undirected song has also been called solitary song [20] , [21] . Thus, in cordon-bleus, solitary song is easily amenable to bioacoustic research as it can be reliably induced under controlled conditions by separating members of a pair from each other.…”

BackgroundBirdsong is a popular model system in research areas such as vocal communication, neuroethology or neuroendocrinology of behaviour. As most research has been conducted on species with male-only song production, the hormone-dependency of male song is well established. However, female singing and its mechanisms are poorly understood.Methodology/Principal FindingsWe characterised the song and its endocrine correlates of blue-capped cordon-bleus (Uraeginthus cyanocephalus), a species in which both sexes sing. Like other estrildids, they produce directed song during courtship and undirected (or solitary) song in isolation, i.e. when the mate is not visible or absent. We compare solitary song of blue-capped cordon-bleus to published descriptions of the song of its relative, the zebra finch (Taeniopygia guttata). Solitary song of cordon-bleus shared some overall song features with that of zebra finches but differed in spectro-temporal song features, sequential stereotypy and sequential organisation. The song of cordon-bleus was dimorphic with respect to the larger size of syllable repertoires, the higher song duration and the lower variability of pitch goodness (measuring the pureness of harmonic sounds) in males. However, in both sexes the overall plasma testosterone concentrations were low (ca. 300 pg/ml) and did not correlate with the sexually dimorphic song motor pattern. Despite such low concentrations, the increase in the rate of solitary song coincided with an increase in the level of testosterone. Furthermore, the latency to start singing after the separation from the mate was related to hormone levels.Conclusions/SignificanceOur findings suggest that the occurrence of solitary song but not its motor pattern might be under the control of testosterone in female and male cordon-bleus.

“…Moreover, estrildids are characterized by having extended pair bonds (Buttefield 1970;Kunkel 1974;Zann 1977). In these non-territonal, long-term pair-bonded birds however, complex vocalizations, differing little in certain respects from typical passerine song (usually confined to males; often elaborate and prolonged; uttered by reproductively capable individuals, fiequently when separated from a conspecific or mate (Hall 1962;Harrison 1962)) are common.…”
