Pectoral Sandpiper and Ruff shot at Titchwell.
Birdwatch Scarcities review July 2017.
The scarce but the
commonest American vagrant to the British Isles a Pectoral Sandpiper turned up at Cley on the
9th September and showed well from the East Bank on the Serpentine. Cley
attracts this species consistently in spring and autumn as it is a very long
distance migrant that has a keenness to go off course. It is actually the
longest distance migrant of any North American shorebird wintering in deepest
South America, Australia and even New Zealand and having breeding grounds in
the Canadian Arctic. The bird at Cley was a juvenile of the year and therefore
has an excuse for being over this side of the Atlantic and way off course. Unusually a Pectoral Sandpiper at Titchwell
Freshmarsh recently at the end of July was an adult in breeding plumage. This
bird was probably a female as it was dull and rather small and the timing
suggesting an early failed breeder. One theory has it that adult
individuals arriving earlier on the east coast may be birds that arrived the
previous year and are undertaking the pattern of north south migration, but on
this side of the Atlantic and wintering in Africa. Another possibility to
consider is that the early birds arriving on the east coast are from the
Siberian population and have therefore come in from the east.
Both Pecs associated with the bulkier Ruff providing a good comparison of the
two similar wader species. Males of both species are larger than females by up
to 30% and can be twice the weight.
Wader return migration is now well under way down on the
Marshes with commoner vagrants much in evidence, the vanguard of much rarer things to come....
