鹳形目
鹤形目
鸻形目
涉禽包括中鹳形目、鹤形目和鸻形目的鸟类。涉禽最主要的特征是“三长”——嘴长、颈长、腿长:长嘴和长颈使得它们能更好地吃到水底下、污泥中或土壤中的食物,如鱼虾、昆虫和小的爬行动物;长腿适于涉水行走,但不适合游泳,腿的长度与其能够涉水的深度直接相关。涉禽大多数在湿地或沿海生活,大多会迁徙。
Waders,also called wading birds,refer to those falling into the order of Ciconiiformes,Gruiformes and Charadriiformes.They are predominantly characterized by their long and agile bills,necks and legs,which to a great extent help them with eating fish,frogs and wading in shallow water.

鹭科Ardeidae(www.xing528.com)
鹭科鸟类在四川比较常见,有12种之多,如白鹭、池鹭、夜鹭、牛背鹭、黄苇鳽、大麻鳽等。它们主要以鱼类为食。
鹭鸟是喜欢群居的鸟儿,常将巢筑在同一个林子里,有时甚至会有几十只鹭鸟将巢筑在同一棵大树上的情况。它们的巢很简陋,除了树枝外,几乎没有什么别的铺垫物。白鹭、夜鹭、牛背鹭共同筑巢的林子里总是非常的喧闹,鸣叫声此起彼落,你呼我应。幼鹭嗷嗷索食,雄鹭间也常有争斗。冲突也会因“第三者”而起,但常以“第三者”被驱赶、家庭得到维护而告终。
鹭鸟是晚成鸟,雏鸟能得到父母的精心照料。幼鹭习飞后,巢就被踏破,等幼鹭离巢,亲鸟也会随之离开,但来年春天,它们又会回到原来的林子里重新筑巢安家。
Widely distributed in Sichuan province,Ardeidae birds are social birds feeding mainly on fishes and resting in simple nests made with merely several twigs.Ardeidae birds are altricial species.Once when the young are capable of flying,parent birds will leave the forests but return to where they lived in next spring,nesting anew.
