震旦鸦雀,是中国特有的珍稀鸟种,被称为“鸟中熊猫”。体长18cm左右。集群大小随季节变化。繁殖季节,多以单只和较小的集群为主;非繁殖季节,以较大集群为主。每年4月,雌雄鸟撕裂芦苇叶片,将叶片中的纤维缠绕在2~5根芦苇上绕成巢样。每窝产卵2~5枚,能孵出2~4只。全球性濒危鸟类。分布仅限于黑龙江下游及辽宁芦苇地和长江流域、江苏沿海的芦苇地。河北衡水、山东济宁、山东东营、上海、黑龙江大庆等地也发现了较为可观的种群,标志着这一物种数量的发展壮大。
It is a rare bird species unique in China and is known as "the panda of birds.",which belongs to the order of Passeriformes.The body length is about 18cm.The cluster size varies with the seasons.During the breeding season, they are mainly in single and smaller clusters;The non-breeding season is dominated by larger clusters.Each April, male and female birds tear the reed leaves and wrap the fibers in the blades around the two to five reeds to build a nest.2 ~ 5 eggs are laid, 2 ~ 4 can be hatched.It belongs to global endangered birds.The distribution is limited to the downstream of heilongjiang and the reed fields of liaoning and the reed fields along the jiangsu coast.Hebei hengshui, shandong jining, shandong dongying, Shanghai, heilongjiang daqing and other places also found a relatively respectable population, marking the growth of this species.
Reed Parrotbill:swing in the deep of the reed sea
震旦鸦雀的体型娇小,身体浑圆,活泼,好动,黄色的小嘴很像鹦鹉。叫声急促而连贯,悦耳、动听,“唱”到高兴处,便会情不自禁地展翅欢歌——它们的翅膀负荷很高,不适合长途飞行,但翅膀扇动的频率极快。
震旦鸦雀飞行能力较差,必须依赖芦苇生存。它们在苇丛中跳来跳去,一不留神便会跃到芦苇的最上端。苇秆、苇叶的顶端细而尖,因承受不了太大重量,它们会忽悠悠地坠下来。不要紧!震旦鸦雀身轻如燕,一个鱼跃蹿至苇尖——“荡秋千”可是它们的拿手好戏。
震旦鸦雀极少到地面活动,一直过着隐士的生活。当人类靠近时,个体或集群常常采取逃逸、警戒鸣叫,作出反应。苇荡是天然的屏障,它们不仅巢穴隐蔽,而且觅食也在苇荡中。
震旦鸦雀主要以芦苇茎内、茎表、叶表上移动能力较差的小虫以及蚧壳虫为食。一旦发现虫子,震旦鸦雀就会像啄木鸟那样,用坚硬的嘴巴不停地敲打苇秆,直到把藏在苇皮子中的虫子揪出来为止。所以,专家称它们为“芦苇中的啄木鸟”。因食物不够丰富,震旦鸦雀不仅种群数量稀少,繁殖率也不高。
震旦鸦雀的名字非常中国化,因为古印度称华夏为“震旦”。它们是中国特有的物种,南京是它的模式标本产地。什么叫模式标本?科学家将世界上第一次发现新的生物种所依据的标本,叫模式标本。上世纪80年代,南京曾有过关于它们的记录。但此后20年再无记录。2007年,专家在江北一片芦荡中发现了震旦鸦雀,足有100只。之后,它们再次从人们的视线消失。直到1991年,在辽河口湿地的芦苇荡中,人们又发现了分散成小群的震旦鸦雀。是浩荡苇海如慈母敞开宽广的胸怀,护佑着这些可爱的小鸟……
Reed Parrotbills are small and round, lively and active, with a yellow mouth that resembles a parrot.The sound is coherent and sweet, when they are happy, they can't help flapping its wings. Their wings of the load is very high, not suitable for long flight, but wings beat frequency is extremely fast.
Because of the capable of flying is weak,they must rely on reeds to survive.They jump around in the reeds, and skip to the top of the reeds.The top of the reed stalk and reed leaves are thin and pointed, because they can't bear too much weight, Reed Parrotbills will fall slowly down.It doesn't matter!It is as light as a swallow, and easily jumps to the point of a reed - "swinging" which is the thing they are good at.
Reed Parrotbills rarely move to the ground, and live the life of a hermit.When humans are close, individuals or clusters often take flight, alert and chirp, and react.The reeds are natural barriers, which not only could hide their nests, but also provide food with the reeds.
They mainly live on small insects with poor mobility on the stems and leaves.Once the worm is found, they would be like a woodpecker, tapping on the stalk with a hard mouth until the worm is out from a reed leather.So experts call them "woodpeckers in reeds".Because the food is not rich enough, Reed Parrotbills are not only sparsely populated, but also have low reproductive rates.
