对圈养的斑胸草雀（Taeniopygia guttata castanotis）和帝汶斑胸草雀（T. G. guttata，进行比较。在多重择偶测试中，一个个体可以表现出对栖息在特定鸟类附近的偏好，但不能形成配对关系（例如，通过聚集在一起）。在成对形成测试中，允许鸟舍中的鸟群中的个体自由形成配对。这两个亚种在择偶测试中更喜欢自己亚种的成员，并在鸟舍中交配。当女性与帝汶男性，其中一半人被画成类似大陆男性，帝汶女性都喜欢和配对未涂帝汶男性，而大陆女性接近未涂和涂帝汶男性，但与后者配对。当内地雄鸟被引入鸟舍时，只有十分之三的内地雌鸟与内地雄鸟重新配对，反映出配对关系的稳定性。雄性和雌性通常与在最初的择偶测试中喜欢的鸟配对，如果那个个体还没有配对的话。在配对后进行的择偶测试中，大多数鸟类更喜欢已经配对的个体。然而，那些最后配对并且没有下蛋的鸟更喜欢他们在第一次择偶测试中选择的鸟，而不是他们在鸟舍中配对的鸟。
Mate choice and pair formation of captive zebra finches from the Australian mainland, Taeniopygia guttata castanotis, and from Timor, T. g. guttata, were compared. In the multiple mate-choice test, an individual could show a preference for perching near a particular bird but could not form a pair bond (e.g. by clumping together). In the pair-formation test, individuals in a flock in an aviary were allowed to form pairs freely. The two subspecies preferred members of their own subspecies in mate-choice tests and mated assortatively in the aviary. When females were presented with Timor males, half of whom had been painted to resemble Mainland males, Timor females both preferred and paired with unpainted Timor males whereas Mainland females approached both unpainted and painted Timor males but paired with the latter. When Mainland males were introduced into the aviary only three out of 10 of these Mainland females re-paired with Mainland males, reflecting the stability of the pair bond. Males and females generally paired with the bird that preferred in the initial mate-choice tests, if that individual was not already paired. In mate-choice tests conducted after pair formation, most birds preferred the individual they had already paired with. However, those that paired last and had not laid eggs preferred the bird they had chosen in the first mate-choice test rather than the individual they paired with in the aviary.
