Ultra-micro structure of eggshell was observed and compositions of eggshell and feather were analyzed. The results showed that the structure of eggshell has special characters besides common structure. The content of poisonous elements in wild great bustard(Otis talda) eggshell and feather is significant lower than that in eggshell of crested foes(Nipponis nippon) and in feather of red crown crane(Grus japonesis) because of less disturbance by people. The contents of 14 elements of female’s feather all are higher than those of male’s.

The results showed that the structure of eggshell has special characters besides common structure. The content of poisonous elements in wild great bustard (Otis tarda) eggshell and feather is significant lower than that in eggshell of crested ibes(Nipponia nippon) and in feather of red crown crane(Grus japonesis) because of less disturbance by people. The contents of 14 elements of female’s feather all are higher than those of male’s.
