The coevolutionary interactions between avian brood parasites and their hosts provide a powerful system for investigating the diversity of animal coloration. Specifically, reciprocal selection pressure applied by hosts and brood parasites can give rise to novel forms and functions of animal coloration, which largely differ from those that arise when selection is imposed by predators or mates. In the study of animal colours, avian brood parasite-host dynamics therefore invite special consideration. Rapid advances across disciplines have paved the way for an integrative study of colour and vision in brood parasite-host systems. We now know that visually driven host defences and host life history have selected for a suite of phenotypic adaptations in parasites, including mimicry, crypsis and supernormal stimuli. This sometimes leads to vision-based host counter-adaptations and increased parasite trickery. Here, we review vision-based adaptations that arise in parasite-host interactions, emphasizing that these adaptations can be visual/sensory, cognitive or phenotypic in nature. We highlight recent breakthroughs in chemistry, genomics, neuroscience and computer vision, and we conclude by identifying important future directions. Moving forward, it will be essential to identify the genetic and neural bases of adaptation and to compare vision-based adaptations to those arising in other sensory modalities.This article is part of the themed issue 'Animal coloration: production, perception, function and application'.
鸟类巢寄生者与其宿主之间的协同进化相互作用为研究动物色彩多样性提供了一个强大的系统。具体而言，宿主和巢寄生者施加的相互选择压力能够产生动物色彩的新形式和新功能，这与捕食者或配偶施加选择时产生的形式和功能有很大不同。因此，在动物色彩研究中，鸟类巢寄生者与宿主的动态关系值得特别关注。各学科的快速发展为巢寄生者 - 宿主系统中色彩与视觉的综合研究铺平了道路。我们现在知道，视觉驱动的宿主防御和宿主生活史促使寄生者产生了一系列表型适应性变化，包括拟态、保护色和超常刺激。这有时会导致基于视觉的宿主反适应以及寄生者欺骗手段的增加。在此，我们综述了在寄生者 - 宿主相互作用中出现的基于视觉的适应性变化，强调这些适应性变化在本质上可以是视觉/感官的、认知的或表型的。我们突出了化学、基因组学、神经科学和计算机视觉方面的最新突破，并通过确定未来的重要方向来得出结论。展望未来，确定适应性的遗传和神经基础以及将基于视觉的适应性与其他感官模式中出现的适应性进行比较至关重要。本文是主题为“动物色彩：产生、感知、功能及应用”特刊的一部分。
