回答1:

因为燕子飞到南方并不是因为它们真的害怕寒冷,燕子这种鸟类羽毛本身就不少,所以怕冷是不存在的,更主要是因为南方哪怕是冬天,食物依然还是比较丰盛的,到处都可以抓到虫子,但是北方的冬天,找一条虫子都很难找到,所以它们真正的目的是要来觅食,但是到了天气转暖了以后,它们还是更喜欢飞回到北方,南方的鸟类比北方更多,因此竞争压力也就大了,它们也不怕累,到了天气回暖了,北方也是有虫子的。

相信大家在小时候都会听过一首儿歌,叫做小燕子穿花衣,年年春天到这里,每年到了春天的时候,燕子都会来到人们的身边,而到了冬天以后还会飞到南方去过冬,当然也有很多人感到奇怪,燕子为什么不留在南方,因为北方到了冬天以后肯定还是会变冷的,其实燕子到了冬天的时候来到南方,并不一定就是因为燕子害怕寒冷,因为燕子本身就是羽毛比较厚实的,鸟类对寒冷相比人类来说还没有那么害怕。

最主要的原因是到了冬天,大多数地方昆虫就开始不多了,哪怕燕子不怕冷,在北方到时候找不到食物还是得饿死,如果大家观察一下身边会发现北方的冬天几乎找不到任何昆虫,只有夏天的时候各种虫子才会多起来,但是南方,特别是广东广西这边气候常年都是温和湿润的,所以虫子到处都可以看得到,很多虫子品种还是北方所找不到的,这个对于大多数鸟类来说都是很具有吸引力,所以候鸟都会在冬天的时候来到南方,不仅仅是为了避寒,也是为了觅食。

但是对于燕子来说,也不能经常待在南方,虽然南方的食物非常多,但是在南方还有很多鸟类会和燕子抢夺生活空间,特别是地处热带的地方,如果燕子长期生活在这里不走,样也会被当地的鸟类所排挤,毕竟任何动物都有排外的习惯,所以燕子到了夏天,还是会回到温带地区,因为到了温带夏天食物也是非常充足的,燕子本身飞行能力就很强,它们不会怕累,飞来飞去他们觉得很开心,当然也有一些候鸟非常的懒惰,有时候干脆就待这里不走了,等到想走再走。

回答2:

因为小燕子是候鸟,需要根据气候来选择生活的地点,所以北方的小燕子会飞到南方过冬,然后还要飞回来。

回答3:

因为南方的夏天是非常炎热的,他们也受不了,他们也需要去北方度过夏天,南方度过冬天。

回答4:

气候宜人的地方,也适合很多小动物的生存,燕子之所以不留在男方是因为竞争者比较多,不利于燕子孵卵和雏燕的生长,而且燕子的飞行能力比较强,所以会飞回来。
