COMMON SANDPIPER (Actitis hypoleucos)
is a small Palearctic wader. This bird and itsAmerican sister species,
the Spotted Sandpiper (A. macularia),
make up the genus Actitis.
They are parapatric and replace each other
geographically; stray birds of either species may settle down with breeders of
the other and hybridize.
Hybridization has also been reportedbetween
the Common Sandpiper and the Green Sandpiper, a basal species of the closely
related shank genus Tringa.
The adult is 18–20 cm long with a
32–35 cm wingspan.
The Common Sandpiper breeds across most oftemperate and subtropical Europe and Asia, and migrates to Africa, southern Asia andAustralia in winter. The eastern
edge of its migration route passes by Palau in Micronesia,
where hundreds of birds may gather for a stop-over. They depart the Palau
region for their breeding quarters around the last week of April to the first
week of May.[INFO:WIKIPEDIA]
