They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.
奔龙类是一类较为特殊的手盗龙类,它具有许多与始祖鸟Archaeopteryx甚至其它早期鸟类相似或接近的特征,主要表现在:叉骨U形与始祖鸟和孔子鸟类的相同,背肋钩状突在孔子鸟类和个别反鸟类中也存在,肩臼窝绝大部分指向侧方类似于始祖鸟,肩胛骨与乌喙骨间的夹角非常接近90°也和始祖鸟的相似,前肢从比例上讲显得较长,大的半月形腕骨使肘部能向侧方折过来,耻骨伸向后下方,距骨上升突与原始鸟类中的为同源结构,羽毛已有显著的分化且具备了现代羽毛的基本结构等等。

By analyzing these indices, combined with their flight behaviors at the airport and its neighbourhood, we identified bird species that have the potential to threaten flight security at Baita Airport; The results showed that the 23 bird species including magpie and red falcon are the most hazard to flight security and the eight bird species including sparrow Hawk and Greenfinch are the hazard.
其结果表明:构成飞行安全威胁有两类:喜鹊和红华等23种鸟类为最危险的鸟类,雀鹰和金翅雀等8种鸟类为较危险的鸟类。

Of 163 species represented by 163 305 individuals had been banded, among them 26 157 birds are Carduelis flammea the most species banded., One banded bird C . flammea banded at the Station was recovered in Norway on February 10, 2003. It is the first bird captured by Europe more than 20 years after the initiation of bird banding program in China.
自1998年开展环志以来,截止2005年12月末,在该地区发现鸟类210种,隶属15目36科,环志鸟类163种163 305只,其中,白腰朱顶雀环志26 157只,是高峰鸟类保护环志站环志数量最多的种类。2003年2月10日挪威回收到由高峰鸟类保护环志站环志的一只白腰朱顶雀,成为中国开展鸟类环志20多年来,欧洲国家回收到的第一只中国环志鸟。

We also analyzed the leg bone proportions of 14 species of Mesozoic birds from the Early Cretaceous of China by using ternary diagrams and comparison with 21 specimens of Cenozoic birds, and concluded that the Early Cretaceous enantiornithines are typical arboreal birds, more basal birds from the Mesozoic are mainly arboreal with some adapted for scansorial life, and the ornithurines are characterized by both arboreal and terrestrial adaptations.
在此基础上,对中国中生代14例鸟类的栖息习性进行了分析,利用三元投影的统计方法,并以国内外新生代21例鸟类标本作为对比参考,得出辽西中生代不同类型鸟类的栖息行为特征:基干鸟类以树栖为主要习性,其中个别鸟类还具有攀援的习性,而反鸟类则是典型的树栖鸟类,今鸟类兼有树、地栖的习性。

Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.
通过实地的观测、采样,并结合其他文献的资料,以相关分析和主成分分析作为数学工具,得知:鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系,鸟类数量分布与两者的相关系数分别为0.916和0.745,其中,底栖生物密度是鸟类数量分布的最直接反映;植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系,通常体积中、大型的鸟类需要较高的植被高度,来作为自己的栖息场所,水禽需要水位较深的区域作为自己的栖息场所;人为活动对鸟类数量分布的影响不大,但对所有自然环境因子都有一定影响。
