本项目通过系统的分类和区系研究工作，共描记云南鸟类848种(1074种和亚种)，占中国记录鸟类种数的64％以上，是目前记录云南鸟类物种最多、最全面和最系统的工作；并在深入研究云南鸟类资源状况和地理分布的基础上，探讨了云南鸟类的区系特征及其演化趋势、三级地理区划。

The coastal wetlands in the Yellow Sea region are important stopover sites for shorebirds along the East Asian-Australasian Flyway. Study on the stopover ecology and migration strategies of shorebirds will be helpful for understanding the mystery of bird migration, and for making conservation strategies on the migrants.

黄海区域为东亚-澳大利亚迁徙路线上鸻鹬类重要的迁徙停歇地，了解鸟类在该区域的生态及生物学特征，阐明鸟类对迁徙停歇地的利用模式和迁徙对策，了解迁徙鸟类对迁徙活动的适应机制，对于进一步认识鸟类的迁徙活动，并制定科学的保护措施具有帮助。

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。

Among 150 species, 32 were adapted to urbanization, 77 adapted slightly to urbanization, 41 were sensitive to urbanization; 37 were interior species, 91 edge species, and 22 insensitive to edge; 93 distributed in only one kind of habitat, 34 in two, 4 in three, and 19 in four.

城市边界对西部山区鸟类群落的影响是双重的，一方面为某些鸟类提供了可利用的资源，另一方面干扰等因素降低了边界区鸟类的多样性，消解了西部山区鸟类群落分布的边缘效应格局。在总体上后者的影响大于前者。

There were distinct differences between ecological habit and the pattern of adaptation of birds of the different species,moreover,the diversity of shape and structure of corresponding tarsometatarsus had differentiated,so the choice of adaptability of avian tarsometatarsus and its corresponding functional behavior had come into being.

鸟类跗跖骨的形态结构表现不仅在脊椎动物中较为特殊，而且在鸟类家族中相互间也存在较大的差异，一方面体现了鸟类跗跖骨形态的多样性，同时也直接影响到鸟类的行为功能的相异性。

Molecular methods of sex identification were studied by amplifying sex gene sequences in five species of ardeidae and one species of threskiornithidae in ciconiiformes birds.

The phylogenetic relationship of raptors and nighthawks were estimated by mitochondrial rRNA gene sequences in this study by comparing the partial basepair fragments of 12S rRNA and 16S rRNA genes among 5 species of Falcoiformes, 3 species of Strigiformes and 1 species of Caprimulgiformes sequenced in this experement, together with the homologous segments of mtDNA in other 17 species of birds downloaded from GenBank.

本文测定5种隼形目鸟类、3种鸮形目鸟类和1种夜鹰目鸟类的部分线粒体12S rRNA基因和16S rRNA基因，结合从GenBank下载的17种鸟类同源基因进行系统进化研究。

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。

Thus , unrestrained tidelands utilization inevitably leads to the competition for habitat between birds and the people , or even destroys the habitat of the birds and reduces their food resources .

这种影响主要体现在破坏鸟类栖息地和减少鸟类食物来源，最终影响到鸟类的生存。
