一天,在路边,看到一老人,肩挑两只筐,筐里装几百只鸡雏叫卖。看那鸡雏毛色或浅黄或白色,在筐内挤来挤去,甚是可爱,于是就买了几只回家。
城里人不会养鸡,就到书店买本养鸡的书,照本宣科,视为宠物来养。把鸡装在纸箱里,铺上报纸,吊上日光灯,最初两周,光照要达到23小时以上,保持温度。
每天铺的报纸要换四五次,以保持卫生。买些鸡饲料,一天要喂七八次。待鸡稍大一些,就弄些小米动物亲情故事100篇、豆渣、菜叶、剩饭什么的来喂。一天要喂五六次。小鸡们小的时候是很好玩的,浑身毛茸茸的,不停地跑来跑去,很是活泼天真。
慢慢地,小鸡们一天天长大了。
有时竟然忽扇着翅膀,飞上飞下,羽毛也渐渐丰满。于是,就把它们放在院子里,喂食的盘子也随放在外。
初放院内,小鸡们似乎不知所措,先是挤在一起,慢慢地在一个角落里找来找去。几天后熟悉了环境,就显得有些好奇、兴奋,每天一放出,就欢叫着飞来跑去,满院找食。
小鸡吃食时,常用爪子把食刨得到处都是,于是,就引来了麻雀。
那麻雀先是立在树的枝头,小心翼翼地察看,后来就飞到离鸡食较远的地方,慢慢地靠近。然后是边看边叨,一有动静,马上飞起。又落在高处观看。有时,天还没大亮,就听到麻雀的鸣叫,原来是它们赶在鸡放出窝之前,寻找昨天遗漏的鸡食。
待鸡们起床出窝时,麻雀已吃完飞走,到别处找食去了。
冬天来了,下雪了,鸡们仍过着衣食无忧的生活,白天吃着人们为它们准备的充足的食物,晚上就卧到人们为它们精心搭造的温暖的鸡窝里。而麻雀这时就惨了,冬天里本来找食就很困难,只能吃一些草籽什么的,这一下雪,找食就更难了。
还要经受雪后冬晚零下十几度北风的寒冷。
记得是多年前,有一天,在单位的办公室里,有一只麻雀突然从开着的窗户间飞进来,大家赶忙把窗户关上,那麻雀在人们的追赶中,慌乱地一头撞在窗玻璃上被逮住,可是它从此不再吃食,喂它什么也不吃,最后硬是活活地饿死了。
我想,也许是它天生的野性,使它不愿被人们关在笼子里。
那时,麻雀是被列为“四害”之一的。理由是它不劳而食,祸害庄稼。这在人都吃不饱肚子的当时,那是绝对不能容忍的。人们在政府的要求下,想尽一切办法来消灭它。包括下毒、设饵笼扣、扎草人吓唬、弹弓、气枪射杀等等。
那真是麻雀的大劫之期。全民动员,老少参与,人人喊打,斩尽杀绝。
但是,小小的麻雀没有被强大的人类灭绝。今天的人类,重新用“生物链”的眼光审视动物,寻求一种人与自然的平衡。于是,麻雀有幸得到了今天人类的保护。
快过年了,鸡也长大了。
突然有一天,在天刚蒙蒙亮时,整个大楼都听到了洪亮的鸡鸣。直接影响邻居和居民的休息。没有办法,只好把自己亲手养肥养大的鸡捉住,送到专门卖鸡的门市,那里有杀鸡的机器,给他两元钱,他就会把鸡杀好宰净,于是,这鸡就做了年菜了。
从此,小院内没有了鸡的喧闹,而只有自由的麻雀们,仍在枝头飞来鸣去,欢乐跳跃,觅食受寒。

PASSAGE 79动物亲情故事100篇:动物行为的研究
Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group动物亲情故事100篇。
These scientists, however, are cautious about the extent to which animals can be credited with conscious processing。
Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered动物亲情故事100篇。
One example of such unexplained behavior: honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern。
The orientation of the dance conveys the position of the food relative to the sun's position in the sky, and the speed of the dance tells how far the food source is from the hive。
Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence。 But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next。
When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food。 No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could have inferred the location of the new site。
Other behaviors that may indicate some cognition include tool use。 Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools。
One researcher has found that mother chimpanzees occasionally show their young how to use tools to open hard nuts。 In one study, chimpanzees compared two pairs of food wells containing chocolate chips。
One pair might contain, say, five chips and three chips, the other four chips and three chips。 Allowed to choose which pair they wanted, the chimpanzees almost always chose the one with the higher total, showing some sort of summing ability。
Other chimpanzees have learned to use numerals to label quantities of items and do simple sums。
