乡村织巢鸟（Ploceus cucullatus）在群体中繁殖，雄性织巢的外壳，并向来访的雌性展示。然后，雌性在不同雄性的巢穴之间进行选择，通常选择新鲜的绿色巢穴。旧巢褪成暗褐色。实验报告表明，巢的颜色是不是一个主要因素，在巢的选择，虽然女性有一种倾向，喜欢新的巢画绿色比新的巢画棕色（z检验，P= 0.07）。他们没有区分绿色油漆和未油漆的巢穴，排除了油漆本身作为选择的基础。有没有显着差异的频率发作的男性显示绿色和棕色油漆的新鲜巢。通常情况下，雄性会在被拒绝的巢穴变成棕色时将其拆除，并在其位置上建造一个新的巢穴。男性撕毁拒绝棕色油漆的巢超过三倍，往往是他们撕毁绿色油漆的巢，表现出厌恶棕色的巢。
The village weaverbird (Ploceus cucullatus) breeds in colonies, and the male weaves the outer shell of the nest which he displays to visiting females. Females then select between nests of the different males, normally choosing fresh green nests. Old nests fade to a dull brown. Experiments are reported that indicate nest colour is not a major factor in the selection of nests, although females had a tendency to prefer fresh nests painted green over fresh nests painted brown (z-test,P= 0·07). They did not differentiate between green-painted and unpainted nests, eliminating paint per se as a basis of choice. There was no significant difference in frequency of bouts of male display of green-painted and brown-painted fresh nests. Normally, males tear down a rejected nest as it turns brown and build a fresh nest in its place. Males tore down rejected brown-painted nests more than three times as often as they tore down green-painted nests, demonstrating an aversion to brown colour in nests.
