Oriental reed warbler: blind "love volunteers"
东方大苇莺是苇田中种群数量最大的鸟类。东方大苇莺常被称为“爱心义工”。为什么这样说?恐怕还得从头说起。
大杜鹃与东方大苇莺同属生物链条中的一环,因此,它们的孵化时间相近,卵的颜色、斑点、大小也几乎相同。于是,大杜鹃眼珠儿一转,“计”上心来。
当大杜鹃在苇丛中飞来飞去的时候,别以为它们是在玩儿。其实,它们是在观察东方大苇莺的巢穴呢——东方大苇莺什么时候产卵?什么时候孵化?当雌大杜鹃快要产卵时,它们更加关注东方大苇莺产卵的数量。大杜鹃的孵化期比东方大苇莺少二三天。当东方大苇莺产卵1~5枚时,大杜鹃便趁机把自己的卵产在东方大苇莺的巢穴里。糊涂的东方大苇莺不知内情,它们每天孵呵孵,最先出壳的竟是大杜鹃幼雏!
大杜鹃幼雏出壳后,需要五六天才能睁开眼睛。不过,那些身材瘦小、全身没长一根毛儿的小东西,出生几个小时后就会做出令人意想不到的“狠毒”事儿。大杜鹃幼雏拚命地叫,表明它们饿了。东方大苇莺马上外出觅食。趁此时机,大杜鹃使出浑身力气,把巢穴中东方大苇莺的卵,用后背一个个拱到巢外去。这样,巢穴中就只剩下它们了!东方大苇莺根本不知道自己的儿女已经惨遭杀害,依然风里来雨里去辛苦觅食,再把食物一口口喂给大杜鹃幼雏!
“吃独食儿”的大杜鹃幼雏越长越大,巢穴都无法容身了,干脆把巢穴踩在脚下,依然心安理得地坐等东方大苇莺送来食物。即使大杜鹃幼雏比东方大苇莺的身体大几倍了,不知情的东方大苇莺还在不停地追撵着喂食给“它的孩子”。大杜鹃亲鸟躲在暗处喜不自禁,见幼雏羽毛渐渐丰满,大杜鹃亲鸟便用独特的叫声唤幼雏回归。等东方大苇莺如梦方醒,悔之晚矣!
在芦苇荡中,常常看见东方大苇莺愤怒地吱吱乱叫,追赶体型比自己大三四倍的大杜鹃,不了解情况的人以为东方大苇莺太勇猛了,那么大体型的大杜鹃也敢较量?反过来说:大杜鹃也太笨了,还怕那么个小东西?孰不知:“杀子”之恨这口恶气谁能咽下?!大杜鹃自知理亏,只好望风而逃了。
Oriental Reed Warbler is the largest population of birds in the reed field.Oriental reed warbler is often called "love volunteer".Why do you say that?I'm afraid we have to start saying from the beginning.
Cuckoo is a same link in the biological chain with the Oriental reed warbler, so their incubation time is similar, and the eggs are almost identical in color, spot and size.Then the cuckoo came up an idea.
When cuckoo flies in the reeds, they are not playing.In fact, they are looking at the nest of the oriental reed warbler.when does the oriental reed warbler lay eggs?When does it hatch?When female cuckoos are about to spawn, they pay more attention to the number of eggs laid by the oriental reed warbler.The hatching period of the cuckoo is two or three days less than that of the Oriental reed warbler.When the Oriental reed warbler lays one to five eggs, the cuckoo takes the opportunity to lay her eggs in the nest of the Oriental reed warbler.Confused Oriental reed warbler do not know the fact, they hatch every day, but the first baby is the big cuckoo chick!
It takes five or six days to open the eyes of the cuckoo chick.But those tiny little creatures that don't have a long hair will call out to show that they are hungry.The Oriental reed warbler goes out to find food.At that moment, the cuckoo pulled out all his strength to arch the baby of oriental reed warbler out of the nest. The Oriental reed warbler did not know that his own children had been killed, still forage food to feed the food to the cuckoo’s chicks!
The big cuckoo chicks grow bigger and bigger,when they grow up, the big cuckoos call their children back with a unique yell.When the Oriental reed warbler realize, it's too late to regret!
In the reeds, you will often see the Oriental reed warbler making yell angrily, pursuing big cuckoo which is bigger than himself.People may think that Oriental reed warblers are so fierce that can fight with cuckoos,and the cuckoos had to run away. In fact they don’t know cuckoos killed their children.
