Abstract

To study the microstructure and difference of remiges in galliformes, the Silver Pheasant (Lophura nycthemera), golden pheasant (Chrysolophus pictus), Blue Eared Pheasant (Crossptilon auritum), Koklass Pheasant (Pucrasia macrolopha), Himalayan Snowcock (Tetraogallus himalayensis) and Thunderbird (Tetrao urogallus) were selected as the representative of six species of endangered birds. The scanning electron microscopy (SEM) was adopted to photograph and count the hooked barbule, cilia and ventral tooth, meanwhile, the single factor analysis of variance of different remiges was carried out by Spss 11.5 software. The results show that remiges are mainly composed of hook feathers and proximal barbule, and there are hook feathers on the side of a small hook, but also with cilia. Proximal barbule is mainly composed of ventral tooth, whose number and shape are the main features. The number of hooked barbule, cilia and ventral tooth of proximal barbule of the remiges of the different birds were significantly different or significant differences among the two species, which could provide the basis for identification.
