Although not extremely rare, the Purple Sandpipers are 
not very frequently met with. This happens partly because 
they seldom form large flocks, and partly on account of their 
confining themselves, while searching for food, to the rocky 
part of the coast. They appear with us about the middle of 
October, and remain until the end of spring. They fly in 
curves, sweeping over the sea when removing from one place 
to another, and now and then emitting a faint shrill cry, in j 
the manner of the Dunlins, which they also closely resemble 
in their mode of walking or rather running along the shore, 
where they search the rocks and fuci for small testaceous I 
mollusca, crabs, and onisci. No instance of their breeding 
in this country has been recorded. They are common in sum- 
mer in the northern parts of Europe and North America. ; 
The eggs are “ pyriform, sixteen lines and a half long, and an ! 
inch across at their greatest breadth. Their colour is yellow- 
ish-grey, interspersed with small irregular spots of pale brown, 
crowded at the obtuse end, and rare at the other.’’
