A replicated, controlled study in 1992 in the North Slope of Alaska, USA (Estelle et al.1996) found that the average daily survival rate of 13 pectoral sandpiper Calidris melanotos nests protected by wire mesh cages was significantly higher than that for 39 unprotected nests (survival rates of 0.98 for caged and 0.72 for uncaged nests). The mesh of the 31 cm tall and 66-69 cm diameter cages was sufficiently large (5 x 10 cm) to allow female plovers to enter and exit, but prevented arctic foxes Alopex lagopus from digging under or entering nests. No protected nests were lost to predation.
