摘要
用扫描电子显微镜对反嘴鹬科Recurvirostridae的鹮嘴鹬Ibidorhyncha struthersii、黑翅长脚鹬Himantopus himantopus不同部位羽毛进行了超微结构观察。结果表明:飞羽、尾羽和体羽主要有有钩羽小枝和无钩羽小枝构成;有钩羽小枝和无钩羽小枝相互啮合形成坚实的羽面来减少飞行阻力。两种鸟类的飞羽、尾羽及体羽的有钩羽小枝中的小钩、纤毛及腹齿数目恒定且相同,可以作为科级鉴定标准。无钩羽小枝中的疣状突起为新发现,数目恒定且不同,可以与绒羽中节状羽小枝节间长度指标作为属级鉴定标准。
This paper reports the microstructure of feathers of Ibidorhyncha struthersii and Himantopus himantopus in different parts of body with SEM.The results show that remiges,rectrices and contour feathers are mainly composed of hooked barbules and nonhooked barbules,the hooked barbules and the nonhooked barbules are engaged to form a flexible and strong vane to reduce the air resistance.The number of hamuli,cilia,ventral teeth is constant in remiges,rectrices and contour feathers.It could be used as a standard to distinguish different families.The verrucous protuberance in nonhooked barbules is special,its variation is stable,so it could be used with the length of internode as a standard to distinguish different genera in the same family.
