我们最近发表了支持的假设，即父母的视觉系统可能会影响雏鸟的可检测性，因此，影响雏鸟的颜色设计在altricial鸟类的演变。我们提供了比较证据的调整雏鸟的颜色设计的父母的视觉系统，我们已经发现在22个altricial鸟类的比较研究。然而，在这个问题上，Renoult等人（J. Evol.生物学：2009）质疑我们研究中的一些假设和统计方法。他们的论证主要基于两点：（1）在我们的研究中，22个样本物种中有4个物种的视觉系统分配不正确;（2）对预测的关联进行系统发育校正的方法不正确。在这里，我们详细讨论了重新分配的视觉系统在这项研究中，并提出了替代解释目前的知识分光光度数据的鸟类色素。我们重新分析的数据，通过使用系统发育广义最小二乘分析，占间接的限制，遗传独立的对比，并根据假设，证实了显着影响父母的视觉系统对张口着色。我们的研究结果被证明是鲁棒的假设视觉系统进化的Laniidae和夜猫子，Renoult等人。生物学：2009年）的研究表明，可能有缺陷的我们的早期发现。因此，我们的比较数据目前支持这一假设，即通过调整父母视觉系统的张口着色，选择增加了雏鸟的可检测性。
We have recently published support to the hypothesis that visual systems of parents could affect nestling detectability and, consequently, influences the evolution of nestling colour designs in altricial birds. We provided comparative evidence of an adjustment of nestling colour designs to the visual system of parents that we have found in a comparative study on 22 altricial bird species. In this issue, however, Renoult et al. (J. Evol. Biol., 2009) question some of the assumptions and statistical approaches in our study. Their argumentation relied on two major points: (1) an incorrect assignment of vision system to four out of 22 sampled species in our study; and (2) the use of an incorrect approach for phylogenetic correction of the predicted associations. Here, we discuss in detail re-assignation of vision systems in that study and propose alternative interpretation for current knowledge on spectrophotometric data of avian pigments. We reanalysed the data by using phylogenetic generalized least squares analyses that account for the alluded limitations of phylogenetically independent contrasts and, in accordance with the hypothesis, confirmed a significant influence of parental visual system on gape coloration. Our results proved to be robust to the assumptions on visual system evolution for Laniidae and nocturnal owls that Renoult et al. (J. Evol. Biol., 2009) study suggested may have flawed our early findings. Thus, the hypothesis that selection has resulted in increased detectability of nestling by adjusting gape coloration to parental visual systems is currently supported by our comparative data.
