摘要: Capsule The third survey of breeding waders in Northern Ireland showed large declines the abundance Eurasian Curlew, Lapwing and Common Snipe since 1987.Aims To estimate size populations selected wader species 2013 population changes previous surveys 1987 1999.Methods Complete all potentially suitable habitats were undertaken randomly 2 km squares each 146 land-dominated 10 km across Ireland. Square selection a two-visit field method replicated conducted 1999.Results estimated to be 526 (±95% CI: 252–783), 860 (277–1545) 1123 pairs (527–1782), respectively. These estimates represent significant 82%, 89% 78% respectively 1987.Conclusion Breeding Com...
