Sanderling G4RYRY

The Sanderling reported between the 5th and 31st December on Oxwich Beach (see post below) was ringed in Iceland at a headland beach site west of Reykjavik as shown above. It is likely this bird belongs to the East Atlantic flyway population and will have been on its way to breeding grounds in northern Greenland or Canada when it was ringed in Iceland. As it has been regular at Oxwich throughout Decemeber, it is likley to be a shorter-distance migrant, compared to many Sanderling that winter as far south as South Africa. Interestingly Reneerkens et al. (2009) [Wader Study Group Bull. 116(1): 2–20.] show that although Sanderling eat small beach invertebrates, the also scavange and show a bird easting flesh from washed-up Ensis subtruncata, a species related to Egg-shell Razor (Pharus legumen) that was photographed being eaten at Oxwich.
