Hetero- and conspecifics effects on nest and chick survival for two listed species; piping plover and least tern breeding on the Missouri River, USA 2007-2016

We present two tabular digital data files representing values related how the presence of hetero- and conspecifics influence nest and chick survival for two listed migratory species breeding on the Missouri River; piping plover (Charadrius melodus) and least tern (Sternula antillarum). We followed 2,507 piping plover nests, 3,251 uniquely banded piping plover chicks, 1,060 least tern nests, and 1,377 uniquely banded least tern chicks from 2007 - 2009, 2012- 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri River in North and South Dakota. Not all study areas were studied in all years. The nest survival dataset includes values for use with the Shaffer logistic exposure model, presence of piping plovers and least terns along with total number of nests of each species within in a variety of distances from a focal nest. It also contains habitat variables specific to certain study areas. The chick survival dataset includes capture histories along with presence of piping plovers and least terns.

本研究提供两份表格化数字数据集，涵盖两类列入保护名录的洄游鸟类的巢与雏鸟存活率受异种及同种个体存在影响的相关参数，这两种鸟类均在密苏里河流域繁殖，分别为笛鸻（Charadrius melodus）和小燕鸥（Sternula antillarum）。研究于2007至2009年、2012至2016年期间，在美国大平原北部区域开展野外监测，共追踪笛鸻巢2507个、佩戴唯一标识环的笛鸻雏鸟3251只，小燕鸥巢1060个、佩戴唯一标识环的小燕鸥雏鸟1377只。研究区域涵盖北达科他州与南达科他州境内密苏里河流域的河道与水库生境。并非所有研究区域在全部观测年份均开展监测工作。巢存活率数据集包含可用于谢弗逻辑暴露模型（Shaffer logistic exposure model）的参数、笛鸻与小燕鸥的种群存在情况，以及距目标巢不同距离范围内各物种种巢的总数量，同时包含部分特定研究区域专属的生境变量。雏鸟存活率数据集则包含捕获历史记录，以及笛鸻与小燕鸥的种群存在情况。
