鸟类的

The avian tarsometatarsus distinguished from the tarsus and metatarsus of other quadruped by its unique characteristic of structure.

鸟类跗跖骨是鸟类后肢骨骼的重要组成部分，也是鸟类后肢运动系统中较为关键的结构。

Birds communicate by songs,and avian vocalization is a main aspect of ornithology.

鸟类鸣声是鸟类交流的"语言"，也是鸟类学研究的主要内容之一。

In addition, based on the analysis of the relationship among tidal flat structure, vegetable distribution and shorebird community, the result showed that tidal flat integrity, length of bulrush zone and algae saline zone, landscape diversity, human disturbance are the four key factors for shorebird to select habitats.

通过分析滩涂结构、植被分布与鸻形目鸟类群落之间的关系发现鸻形目鸟类对生境选择中，滩涂结构完整度、藨草带和光滩带的宽度、周边景观的多样性、人为干扰程度都是影响鸻形目鸟类栖息地选择的关键因子。

Based on the analyses of the diversity of shape and structure of tarsometatarsus of living birds and its corresponding function, we can study the shape and habit of birds in the early stages, at the same time can discuss the evolutive law of functional behavior of birds in the different periods of the geologic history further too.

特别是通过对现生鸟类跗跖骨形态结构多样性与对应功能的分析，可以此作为研究早期鸟类形态习性的参考依据，同时也可进一步探讨不同地质历史时期鸟类功能行为的演化规律。

In particular it can base on the analyses of the diversity of shape and structure of tarsometatarsus of living birds and its corresponding function,to study the shape and habit of birds in the early stages,at the same time can discuss the evolutive law of functional behavior of birds in the different periods of the geologic history further too.

The tibiotarsus of hindlimbs of typical terrestrial birds with the characteristic accustomed to walk and run is the longest, and its tarsometatarsus is longer than the femur; while the tibiotarsus of hindlimbs of typical arboreal birds with the characteristic of perching, jumping is the longest, and its femur is longer than the tarsometatarsus; the contrast of length of femur and tarsometatarsus of raptores change between the two former types of birds because its life habit is intervenient of them.

习于地面行走、奔跑为特征的典型地栖鸟类，后肢骨骼中胫跗骨最长，其次跗跖骨长度大于股骨；而以树上栖息、跳跃为特征的典型树栖鸟类，后肢骨骼中胫跗骨最长，而股骨长度大于跗跖骨；猛禽类因生活习性介于前两类鸟类之间，故股骨与跗跖骨长度比较也是在二者之间变化的。

Among them,153 (43 22%),164 (46 33%),and 37 (10 45%) species are the avian of Palaearctic region,Oriental region and Cosmopolitan respectively.

类群多样性分析显示，以中小型鸟类为主的雀形目鸟类对三峡库区鸟类多样性贡献最大，秭归具有最大的类群多样性，而巴东则具有最多的物种数。

The birds of Passeriformes have more important contribution to the group diversity in the Three Gorges Reservoir. Zigui County has the maximal family diversity,while Badong County has the upmost species composition.

Avian influenza, or fowl plague, is a potentially devastating disease, predominantly of chickens and turkey s, although the virus can also affect game birds, ratites, psittacine and passerine birds.

禽流感，也叫真性鸡瘟，是一种潜在的毁灭性的疾病，主要感染鸡和火鸡，同时也可感染鸟类，平胸鸟类，鹦鹉和雀形目鸟类。
