摘要

在多个进化支的鸟类分类群中都观察到翼辅助倾斜奔跑(WAIR)。它在现代鸟类中广泛的系统发育分布表明它是鸟类的祖先特征。据推测，WAIR作为一种行为早于全动力飞行的进化，并形成了陆地和空中生命之间的行为和生理垫脚石。在这里，我报告了在加拿大安大略省圭尔夫市的一个城市后院偶然部署的跟踪摄像机拍摄到的普通白头翁(Quiscalus quiscula)的明显WAIR的观察。据我所知，这是第一次有文献记载的观察到Icteridae家族的明显WAIR。此外，它强调了非系统地使用跟踪相机进行独特的自然历史观测的价值。

Apparent wing-assisted incline running in a Common Grackle (Quiscalus quiscula)

Wing-assisted incline running (WAIR) has been observed in bird taxa from multiple clades. Its wide phylogenetic distribution in modern birds suggests that it is an ancestral trait for class Aves. WAIR as a behaviour is speculated to predate the evolution of full-powered flight, and to have formed a behavioural and physiological stepping stone between terrestrial and aerial life. Here I report an observation of apparent WAIR in a Common Grackle (Quiscalus quiscula) photographed incidentally on a trail camera deployed in an urban backyard in Guelph, Ontario, Canada. To my knowledge this is the first documented observation of apparent WAIR for the family Icteridae. Furthermore, it highlights the value of non-systematic use of trail cameras for making unique natural history observations.
