由于南半球研究的缺乏，对雀形目动物生活史的地理和系统发育变异的理解受到了阻碍。我们记录了澳大利亚特有的白眉鹪鹩（Sericornis frontalis）的繁殖生物学。与其他翼翅鸟一样，翼翅鸟的产卵间隔较长（2天），孵化期较长（整个季节从21天减少到17天），羽化后的亲代照顾期较长（6至7周）。鹪鹩似乎是典型的澳大利亚鸦科动物，它们的蛋量小（3个蛋），繁殖季节长（5.4个月），而且它们的繁殖间隔也很长（尝试失败后10天，成功后21天）。鹪鹩是多窝的，经常能成功地养育两窝，偶尔也会养育三窝。鹪鹩的繁殖生物学进一步支持了鸦科成员独特的生活史策略的说法，但也强化了一些“鸦科”生活史特征更具体地说是Pardalotidae的证据。
Abstract An understanding of geographic and phylogenetic variation in passerine life histories is hampered by the scarcity of studies from the Southern Hemisphere. We documented the breeding biology of the White-browed Scrubwren (Sericornis frontalis), an Australia endemic in the Pardalotidae (parvorder Corvida). Like other members of the Pardalotidae, scrubwrens had a long laying interval (two days), a long incubation period (declining from 21 to 17 days through the season), and a long period of postfledging parental care (6 to 7 weeks). Scrubwrens appeared to be typical of the Australian Corvida in having a small clutch size (three eggs) and a long breeding season (5.4 months), and they also had a long interval between breeding attempts (10 days after a failed attempt, 21 days after a successful attempt). Scrubwrens were multibrooded, often raising two broods successfully and occasionally raising three broods. The breeding biology of scrubwrens adds further support to claims of a distinct life-history strategy for members of the Corvida but also reinforces evidence that some “Corvida” life-history traits more specifically are those of the Pardalotidae.
