鸟类蛋壳上的斑点有可能作为身份信号，这些信息可以帮助雌性识别它们的蛋/巢或拒绝由异种或同种卵寄生虫产下的外来蛋。在鸟类以密集的群落筑巢的情况下，识别蛋可能是适应性的，因为同种育雏寄生的报告在群落筑巢物种中过度代表。我们利用燕子和燕子（Hirundinidae）的繁殖生物学（单独与殖民繁殖）和蛋壳表型的变化来测试这些特征之间的相关进化，同时也考虑了巢型，因为斑点可能会掩盖开杯巢中的蛋。我们发现，有斑点的蛋更有可能是由社会繁殖的物种产下的，它们建造的开放式巢比黑暗的巢更容易看到斑点。
Maculation on avian eggshells has the potential to serve as an identity signal, and this information may help females recognize their eggs/nest or reject foreign eggs laid by hetero‐ or conspecific brood parasites. Recognizing eggs could be adaptive in cases where birds nest in dense colonies, as reports of conspecific brood parasitism are over‐represented in colony‐nesting species. We utilized the variation in breeding biology (solitary vs. colonial breeding) and eggshell phenotype in swallows and martins (Hirundinidae) to test for correlated evolution between these traits, while also accounting for nest type, as maculation may camouflage eggs in open‐cup nests. We found that maculated eggs were more likely to be laid by species that breed socially and build open‐cup nests where maculation would be more visible than in dark cavity nests.
