|Family XXXVI. SCOLOPACINE. SNIPES.
GENUS I. TRINGA, Linn. SANDPIPER.
THE PURPLE SANDPIPER.
|Genus||TRINGA MARITIMA, Brunn.
I am surprised that my worthy friend THOMAS NUTTALL speaks of this species as being scarcely ever seen in the United States, where, to my knowledge, it is
on the contrary very abundant, and nowhere more so than in the neighbourhood of
the Harbour of Boston, in the markets of which city it is sold in autumn and
winter. When I was there, a gunner whom I employed brought me several dozens,
which he had killed in the course of a single afternoon. I have also seen some
in the markets of New York. Farther south, however, they are rarely met with.
Timid though not shy, they are seen in flocks of eight or ten, on the rocky shores of the sea. They seem to shun sandy beaches, and seldom advance far inland. While I was on the Bay of Fundy, I observed numerous small flocks winging their way northward, in the month of May. On one occasion, a flock alighted almost at my feet, so that I was obliged to retire to a proper distance before shooting at them.
Their flight is pretty rapid, and when necessary sustained, for I have observed them flying in compact bodies across the Gulf of St. Lawrence. When started along the shores, they emit a feeble weet, which is repeated two or three times, take a sweep over the water, and return to the same spot or near it, somewhat in the manner of the Spotted Sandpiper. They are generally very busy while searching for food, run nimbly with the body lowered on the legs, which are much bent, go to the edge of the water, seize on small shell-fish, shrimps and worms, and search industriously among the sea-weeds for marine insects. Their marked predilection for rocky shores has caused them to be named "Rock Snipes" by the gunners of our eastern coast. In autumn and winter the young birds become fat, and afford delicate eating.
I was sadly disappointed at not finding them breeding on any part of the coast of Labrador which I visited, the more so because Dr. RICHARDSON says they are abundant on the shores of Hudson's Bay, where they breed. He gives no description of the nest or localities on which they deposit their eggs, which are said to be "pyriform, 16 1/2 lines long, and an inch across at their greatest breadth. Their colour is yellowish-grey, interspersed with small irregular spots of pale brown, crowded at the obtuse end, and rare at the other."

The principal differences in the winter plumage are, that the lower parts are pale grey, while the upper have the purple tints much fainter, the white edgings substituted by dull grey.
