笼养丹顶鹤的繁殖行为观察

The observation of the reproductive behavior of the Red-Crowned crane under cage culture

丹顶鹤 (Grusjaponensis)俗称“仙鹤” ,其繁殖行为释放是一系列反射活动。笼养能引起丹顶鹤某些繁殖行为成分量的变化 ,但不能引起质的变化即并不会出现新的繁殖行为。在丹顶鹤的性行为程序中 ,行为成分常以固定动作方式有节律地反复演示 。

The vulgar name of Grus japonensis is red-crowned crane.The release of its reproductive behavior is composed of a series of reflective activities.Although cage culture may cause quantive change of the composition of the bird's reproductive behavior,this cannot bring about the qualitative change,which means that new reproductive behavior will not emerge under the conditions of cage culture.In the process of the sexual behavior of the red-crowned crane,the behavioral composition is repeatedly demonstrated rhythmically with fixed movement,indicating the characteristic of ritualization.
