Results showed
that a high proportion of nests failed. The main causes of nest failure
were predation
22%, trampling by humans 10% and desertion 8%. Some pairs attempted
nesting on no less than five occasions in a breeding season. Fledging
success was very poor. At one time the Wash population of Ringed Plovers were thought to be mainly sedentary but our study has shown that the breeding population at Snettisham/Heacham on the east Wash mainly do not winter here. They have been seen in west and south west Britain and Wales, in Ireland, and also in France as far south as 46-09N 01-15W. There have also been several recoveries from northern England, on both the north-west and north-east coasts and in Scotland. In other words few of our colour ringed birds were wintering on the Wash! But some birds returned as early as February. View map of some recoveries and colour ring sightings of Ringed Plovers from Snettisham and Heacham. The project also revealed that whilst many individuals did not winter in the study area some were consistently returning to the same wintering area. NW33313 was seen in Scotland in 2007, 2011, 2012 and 2014. Whilst adults appeared to be faithful to the breeding area and returned in successive years some chicks that fledged did not return and relocated to another area where they stayed to breed. At least one NW16750 went to the Netherlands where it stayed to breed. Two others NV81356 and NV94369 went to Blakeney Point, Norfolk where they remained and bred there for many years. Their life histories can be seen here. Some Photos of our colour marked Ringed Plovers can be seen here. |
