在加州洛杉矶[美国]的一个大型室外鸟舍中，对非洲乡村织巢鸟（P. cucullatus）的巢选择的决定因素进行了实验研究。雄性是一夫多妻制的，每只雄性都试图通过一种特殊的展示来吸引未交配的雌性，他用从棕榈或草的叶子上撕下来的带子编织了一个巢。雌性更喜欢新鲜的绿色鸟巢，编织的紧密性和外观似乎没有材料的强度那么重要。巢龄与其可接受性之间有很高的相关性。雌性会忽略那些已经褪成暗褐色的旧巢，但把这些巢涂成绿色并不能恢复它们的吸引力。新鲜的，最近建造的巢穴被雄性展示给雌性最多。有些雌性会选择相同的雄性和领地进行连续的窝卵。
An experimental study of factors determining nest selection by the female was made in a colony of African village weaverbirds (P. cucullatus) in a large, outdoor aviary at Los Angeles, California [USA]. The males are polygynous and each attempts to attract unmated females by a special display to the nest he has woven of strips torn from leaves of palms or grasses. Females prefer fresh green nests, and closeness of weave and external appearance did not seem to be as important as strength of materials. There was a high correlation between age of nests and their acceptability. Females ignore old nests that have faded to a dull brown, but painting such nests green did not restore their attractiveness. The fresher, more recently built nests were advertised the most to females by the male''s display. Some females choose the same male and territory repeatedly for consecutive clutches or broods.
