Stable hydrogen isotope values of spring migrants and wintering Rallus limicola of unknown origin

δD of feathers collected from wintering Rallus limicola on the Louisiana and Texas coastal plains and from a spring migration stopover site in the Lake Erie marshes of Ohio, USA. Contour feathers were sampled from spring migrants to determine their winter provenance and primary feathers were sampled from wintering rails to determine their previous breeding location.

本数据集涵盖采自美国路易斯安那州与得克萨斯州沿海平原越冬的长嘴秧鸡（Rallus limicola），以及美国俄亥俄州伊利湖湿地春季迁徙停歇地的长嘴秧鸡的羽毛的氢同位素δD比值。研究人员从春季迁徙个体采集廓羽（contour feathers），以确定其越冬起源；同时从越冬秧鸡采集初级飞羽（primary feathers），以明确其此前的繁殖地点。
