Monitoring of shorebirds reproduction on Bylot Island, Nunavut, Canada

Nests are mainly found through systematic searches of a 4.5 km2 core area near our main field station from early June to early July since 2005. Nests are also found opportunistically while conducting other field activities over the study area. Once found, nests are positioned with a GPS receiver. Each nest is then visited during the breeding period to determine clutch size, laying and hatching dates and hatching and fledging successes. Nests found the main research area are monitored more intensely (every 2 to 6 days) while those located elsewhere are monitored less intensively.

自2005年起，巢穴主要通过对我主研究站附近4.5平方公里核心区域的系统性搜索在每年的六月上旬至七月上旬被发现。在执行研究区域内的其他野外活动时，也会偶然发现巢穴。一旦发现巢穴，便利用GPS接收器进行定位。在繁殖期间，对每个巢穴进行访问，以确定蛋巢大小、产蛋和孵化日期，以及孵化成活和离巢成功率。位于主研究区域的巢穴受到更频繁的监测（每2至6天一次），而位于其他位置的巢穴则受到较为稀疏的监测。
