虽然家庭Vangidae提供了一个最显着的例子，适应性辐射在马达加斯加的鸟类区系，每个物种的繁殖生物学的基本信息是缺乏的。为了研究繁殖系统的白头Vanga Leptopterus viridis，马达加斯加特有的物种，我们研究了9对（涉及9个带状个人）的男性和女性的筑巢，孵化，育雏，喂养年轻的贡献。这项研究于1999年和2000年11月至12月在Ankarafantsika（Ampijoroa）的严格自然保护区进行。男性捍卫分散的领土，个别男性与单一的女性配对，所有观察到的交配发生在女性和男性的领土上，他们嵌套。在筑巢阶段，雄鸟和雌鸟提供相同比例的材料。两性都参与孵化和育雏。在雏鸟期，两性都向雏鸟提供食物（主要是蜘蛛和毛毛虫）。在九对中的两对中，对和额外的鸟，其大覆羽正在蜕皮共享领土和额外的鸟allopreened与对。使用CHD基因性别鉴定方法，我们确定这些额外的鸟类中有两只是雄性。这些额外的雄性并不帮助喂养幼崽，但它们围攻接近巢穴的动物。这些结果表明，白头万加斯是合作繁殖者（单一繁殖类型），未成熟的雄性协助围攻。
Although the family Vangidae provides one of the most striking examples of adaptive radiation in the avifauna of Madagascar, basic information on the breeding biology of each species is lacking. To examine the breeding system of the White-headed Vanga Leptopterus viridis, a species endemic to Madagascar, we studied the contributions made by males and females of nine pairs (involving nine banded individuals) to nest building, incubating, brooding, and feeding the young. The study was conducted from November to December in 1999 and 2000 at the Strict Nature Reserve of Ankarafantsika (Ampijoroa). Males defended dispersed territories, individual males paired with single females, and all observed copulations took place between females and males on whose territories they nested. During the nest-building stage, males and females provided material in equal proportion. Both sexes participated in incubating and brooding. During the nestling period, both sexes delivered food (mainly spiders and caterpillars) to the nestlings. In two of nine pairs, pairs and extra birds whose greater coverts were molting shared the territory and extra birds allopreened with pairs. Using the CHD gene sexing method, we determined that two of these extra birds were males. These extra males did not help feed young, but they mobbed animals that approached the nest. These results suggest that White-headed Vangas are cooperative breeders (of the singular-breeding type), where immature males assist in mobbing.
