1. The relationship of six species from Alaudidae (Alauda arvensis Melanocorypha mongolica Calandrella cinerea Calandrella cheleensis Eremophila alpestris Galerida cristata) distributed in Inner Mongolia were studied from three aspects: Mostly in feather keratins, chromosomal karyotype and morphology adding. The contour feather vance, down feather and shaft of six Larks were studied by means of SDS-PAGE of feather keratins.
    本文在羽毛角蛋白、染色体核型及形态学三个层次上，以羽毛角蛋白凝胶电泳分析为主，以染色体核型分析和形态学分析为参考，对分布于内蒙古地区的百灵科Alaudidae的6种百灵鸟的亲缘关系进行研究，包括云雀Alauda arvensis、蒙古百灵Melanocorypha mongolica、短趾百灵Calandrella cinerea、亚洲短趾百灵Calandrella cheleensis、角百灵Eremophila alpestris、凤头百灵Galerida cristata。

2. The result of clustering analysis showed that the relationship between Alauda arvensis and Melanocorypha mongolica was closer than others; the relationship between Eremophila alpestris and Calandrella cinere was closer than that between Eremophila alpestris and Calandrella cheleensis. But the relationships between the five birds and Galerida cristata were all far.
    羽毛角蛋白凝胶电泳是在生物大分子的层次上，对6种百灵鸟的正羽羽片、绒羽和正羽羽茎角蛋白进行SDS-PAGE，聚类分析表明：云雀和蒙古百灵的亲缘关系较近；角百灵与短趾百灵亲缘关系最近，与亚洲短趾百灵的亲缘关系次之；而凤头百灵与这五种百灵的亲缘关系均较远。

3. Species like Eurasian Skylark Alauda arvensis, Red-backed Shrike Lanius collurio, Corn Bunting Miliaria calandra, Northern Lapwing Vanellus vanellus and Eurasian Tree Sparrow Passer montanus are familiar names in the long list of declining farmland bird species.
