资源简介：
We are monitoring the nesting activity and density of shorebirds. We find nests through systematic search of 12-ha plots in mesic upland heath and hydric meadow tundra. Many nests are also found opportunistically. Nests found are positioned with a GPS and revisited during the breeding period to determine laying date, clutch size, hatching date and fledging success.
