Physically protect nests with individual exclosures/barriers or provide shelters for chicks of waders
A small randomised, replicated and controlled trial in 1978 on a beach on Lake Erie, Canada (Nol & Brooks 1982) found that predation rates of killdeer Charadrius vociferous nests were not significantly different between 12 nests protected with a novel predator exclosure (‘H’ shaped frame with the nest in the centre and eight 7 x 12 cm openings, covered in 1.4 cm mesh hardware cloth) and 17 control nests (75% of protected nests and 71% of unprotected nests predated). However, no protected nests were lost to avian predators (gulls Larus spp. or American crow Corvus brachyrhynchos). Instead they were predated by raccoons Procyon lotor or mustelids which could enter exclosures.
