The sandpipers breed on the arctic tundra which is in northern Canada, with water nearby. One egg is laid each day for four days. They can raise four young. The eggs are incubated by both female and male sandpipers. When the egg hatches, the young ones start to forage for insects. The young look for food in the wetlands of the Arctic tundra and mudflats. The young are left by their mothers at the age of 10 days and they gain the ability to fly at the age of 14 days. Although the fathers, continue to care for the young for 19 days.
