鸟类翅膀的特征是为了飞行而进化的，这似乎与脚的形状和脚印中反映的行走能力有着明显的关系。收集和分析了现代鸟类的翅膀面积、翼展和体重数据，以量化可能的相关性，这在以前只是从经验数据中推断出来的。判别分析表明，鸟类翅膀可以分为三个栖息地组，以类似的方式足迹。多元回归分析表明，鸟类的翼载和展弦比与足迹形状参数相关，可以用一个简单的方程表示。这一结果可能反映了鸟类运动对栖息地的适应。翼面积和翼展之间的关系，以及翼面积和足迹面积之间的关系，这是明显的现代鸟类，推导出并用于估计翼面积和翼展从灭绝的白垩纪鸟类类群的足迹。体重、翼展和翼面积的估算值表明，梅氏古鸟、周氏黄山脚和雅可布氏古鸟分别具有与鹭（或鹤）、大型鹬（或小型海鸟）和中型似鸥鸟类相似的体型。
The characteristics of avian wings that evolved for flying appear to show a distinct relationship to the shape of the pes and walking abilities as reflected in footprints. Wing area, wing span and body weight data of modern birds were collected and analysed in order to quantify the possible correlation, which was previously only inferred from empirical data. Discriminant analysis demonstrated that avian wings can be divided into three habitat groups, in a similar way to footprints. Multiple regression analyses revealed that the avian wing loading and aspect ratio were correlated with the parameters of footprint shape and can be expressed by a simple equation. The results may reflect the adaptation of avian locomotion to habitat. The relationships between wing area and wing span, and between wing area and footprint area, which are apparent in modern avians, were derived and used to estimate wing area and wing span from the footprints of extinct Cretaceous avian taxa. The estimated values of body weight, wing span and wing area suggest that the trackmakers ofArchaeornithipus meijidei,Hwangsanipes choughiandYacoraitichnus avishad bodies similar to herons (or cranes), large sandpipers (or small sea birds) and medium‐sized gull‐like birds, respectively.
