中文摘要:75种陆栖性鸟类(雀形目50种,非雀形目25)的鸟羽为研究对象,在扫描电镜(SEM)下观察翼上覆羽和两胁绒羽的显微结构,计数正羽不同部位的羽小枝小钩个数、纤毛对数、腹齿个数、背刺个数,测量绒羽羽小枝的节间长度、节直径、羽小枝直径、色素长度,并对绒羽节的形状进行描述和归类。结果表明,在正羽有钩或无钩羽小枝上,腹齿数均恒定,而在有钩羽小枝上小钩个数和纤毛对数之和在48%的研究对象中保持恒定,据此提出这两个特征参数可作为正羽显微结构特征运用于鸟种鉴定。在绒羽显微特征中,节间长度、节直径、羽小枝直径3项参数可区分雀形目和非雀形目种类,可在鉴定中作为正羽显微结构的补充。以上工作是应用鸟羽显微结构进行物种鉴定工作的探索,为今后构建鸟羽特征数据库奠定了一定的基础。
英文摘要:We sampled pennaceous, wing covert feathers and downy, flank feathers from 75 bird species (50 passerine and 25 non-passerine species). Feathers were collected from museum specimens and captured wild birds. Three barbs from the proximal to distal end of the wing feather were cut off. Then each barb was taken 3~4 photographs using scanning electron microscope (SEM), and a total of 9~12 photographs were taken from each pennaceous. The microstructures including hamuli, cilia, ventral teeth, and dorsal flanges were compared among species. The number of ventral teeth was the most constant pennaceous character with no significant variation between different barbs or sampled feathers, indicating that this character could be used in the identification of avian species. The total number of the hamuli and cilia was stable in 48% of the sampled species. This value could be a second indicator used for identification. Three different barbs from the flank plumulaceous feather were cut off and were taken 2~3 photographs respectively, totally 6~9 for each sampled feather. Four parameters on plumulaceous nodes were measured, three of which including internode length, node diameter, and barbule diameter could be used to separate passerine and non-passerine species according to our analysis. However, the fourth parameter, pigmentation length in downy feathers varied greatly among species and also caused some uncertainties during measuring. We suggest that the pigmentation length should be ignored in further identification attempts. In conclusion, a detailed feather microstructure database should be established before this method can be applied in avian species identification.
