🐦Killdeer
双领鸻（學名：Charadrius vociferus）是是一种发现于美洲的大型鸻。1758年，卡尔·林奈在《自然系统第10版》中描述并赋予了它现在的学名。描述了三个亚种。它的上半身大多是棕色的，带有红褐色的流苏，头部有白色和黑色的斑块，胸部有两条黑色带。腹部和胸部的其余部分是白色的。 指名亚种（即最初被描述的亚种）的繁殖区域涵盖从美国阿拉斯加东南部、加拿大南部直至墨西哥的广大地区。在该繁殖区南半部常年可见其踪迹；亚种C. v. ternominatus常驻西印度群岛，而C. v. peruvianus亚种则全年栖息于秘鲁及周边南美国家。北美繁殖种群的越冬范围从其常驻地南至中美洲、西印度群岛以及南美洲最北端地区。 双领鸻主要以昆虫为食，但也会吃掉其他无脊椎动物和种子。由于其分布范围和种群数量大，它以前被世界自然保护联盟视为无危物种，但由于其种群数量下降，现在被认为是近危物种。
