适应性辐射是一个合适的系统研究的（共同）进化的性状，因为地理的限制应该是次要的。鸟类喙形态的适应性辐射是一个典型的例子，但其他特征的进化仍不清楚。在这里，使用比较系统发育分析，我们研究了羽毛颜色与陆地：空中运动在马达加斯加Couas。我们假设，红褐色的着色将有利于在地面上的隐，并发现，红褐色的着色增加与地面：空中运动的相对投资，测量为跗骨：翅长比。陆栖动物：空中运动可以解释羽毛颜色的多样性，至少部分如此。
Adaptive radiation is a suitable system for the study of the (co)evolution of traits because phylogeographic constraints should be of minor importance. Adaptive radiation of beak morphology in birds is a classic example, but the evolution of other traits remains unclear. Here, using a comparative phylogenetic analysis, we studied plumage coloration in relation to terrestrial:aerial locomotion in Malagasy Couas. We hypothesized that rufous coloration would be beneficial for crypsis on the ground, and found that rufous coloration increased with the relative investment in terrestrial:aerial locomotion, measured as tarsus:wing length ratio. Terrestrial:aerial locomotion may explain the diversity of plumage coloration, at least in part.
