鸟类的筑巢、孵卵、育雏等一系列行为属于(  )

A.学习行为

B.先天性行为

C.社会行为

D.防御行为

答案

先天性行为是指动物生来就有的,由动物体内的遗传物质所决定的行为,称为先天性行为,例如:蜜蜂采蜜,蚂蚁建巢,蜘蛛织网,鸟类迁徙等.先天性行为是动物的一种本能行为,不会丧失.

后天性行为是动物出生后通过学习得来的行为.建立后天行为的主要方式是条件反射.参与神经中枢是大脑皮层不是与生俱来的而是动物在成长过程中,通过生活经验和“学习”逐渐建立起来的新的行为.

社会行为是群体内形成了一定的组织,成员间有明确分工的动物群集行为,有的高等动物还形成等级.

防御行为:为了保护自己,防御敌害的各种行为都是防御行为.如逃跑、装死、释放臭气、保护色、警戒色、机体防御等.

鸟类的筑巢、孵卵、育雏等一系列行为,是生来就有的,不学就会的,由体内的遗传物质所决定的先天性行为;还属于繁殖行为.

故选:B.
