Cuckoo: the lonely bird doesn't talk
大杜鹃是森林中最喜欢鸣叫的鸟类之一，在我国分布较广。大杜鹃常常喜欢在晨间鸣叫，有统计显示，大杜鹃的叫声平均每分钟24～26次，连续鸣叫半小时，稍稍停息一下。
杜鹃生性怕羞，喜欢隐匿在密林深处，虽然能听到它们的声音，可是难睹芳容。其中，四声杜鹃更为神秘。不知道它们是不是每次只叫四声，还是叫声以“四”为一组。还有人说，只有四声杜鹃才叫谷布。其余的杜鹃都不能随便归于“谷布”之列。
提起布谷，一定不会陌生。“布谷——布谷——”叫声短促、迅疾、清悠、欢悦。人们习惯把它们的叫声演绎成：“播谷——播谷——”或者：“阿公阿婆，割麦插禾。”割麦，是南方的农事；对于北方来就，大杜鹃在提醒“插禾”。
大杜鹃一到，就意味着春天结束、初夏来临了。于是，鸟儿们开始繁忙地求偶、婚配、孕育、孵化，新一轮生命重又开始蓬勃地生长。没人赋予大杜鹃这样的义务，但它们总是钟表一样准时地唤醒着、敦促着。
大杜鹃无固定配偶，也不自己营巢和孵卵，而是将卵产于东方大苇莺、麻雀、灰喜鹊、伯劳、棕头鸦雀、北红尾鸲、棕扇尾莺等雀形目鸟类巢中，由这些鸟替它带孵带育。
大杜鹃是湿地中较为孤寂的鸟儿之一，表现出出奇的温顺与安宁，从面目表情上，也看不出喜怒哀乐。但是仔细听，从鸣叫中似乎能听出流离、失落的滋味。在春夏之际，大杜鹃会彻夜不停地啼鸣，那种凄凉、哀怨的悲啼，常常会激起人们无限的情思。再加之，大杜鹃的口腔上皮和舌头都是红色的，人们便善意地“将错就错”，主观地认为它们忠贞不贰——快瞧！都“啼”得满嘴是血了！于是，还引出“杜鹃啼血”等许多哀婉的诗篇和美丽的传说。
Cuckoo is widely distributed in China and likes chirping most.They prefer to chirping in the morning, it’s said that the sounds are average 24 to 26 times per minute, with a continuous of half an hour and a little rest.
The cuckoo is shy and likes to hide in the depths of the dense forest. Although it can be heard, it is hard to see. Four voice cuckoos are more mysterious.People don't know if they're called four voice, or a group of “four”.Others said that only four cuckoos are called true cuckoos.The rest of the cuckoos can't be classified as "true cuckoos".
It must be familiar to mention the cuckoo.The voice of"cuckoo - cuckoo -" is short, quick, clear and happy.People used to interpret their sound as "sowing the grain -- the sowing grain --" to remind the farmer of crapping.
When cuckoo arrives, it means that spring is over and early summer comes.So the birds began to get busy mating and incubating, and a new life began to flourish again.No one endowed the cuckoo with such obligations, but they always woke up and urged on time.
Large cuckoo has non-fixed spouse, nor nesting and hatching by themselves, because they produced their eggs in the nest of oriental reed warbler, sparrows, brown head crow finches,and other birds from the order of passeriformes.
The cuckoo is one of the more lonely birds in the wetland.We can not see happiness and sorrow from their facial expression.But listen carefully, it seems that the feeling of displacement and loss can be heard from the chirping.In the spring and summer, the cuckoo would be singing incessantly all night, and the sad voice would often arouse people's infinite love.In addition, the large cuckoo's mouth epithelium and tongue are red, people subjectively think they are faithful,because their mouth is full of blood!Thus many sad poems and beautiful legends about cuckoos are introduced.
