THE PECTORAL SANDPIPER. [Pectoral Sandpiper.] |
Genus | TRINGA PECTORALIS, Bonap. [Calidris melanotos.] |
This Sandpiper is not uncommon along the shores of our Eastern States in autumn and winter. It has also lately been found in England, and I have seen a
specimen of it in the possession Of WILLIAM YARRELL, Esq. of London, who
received it from a person who had shot it not far from the metropolis. I first
met with this species in the immediate vicinity of Dennisville, in the State of
Maine, feeding on the rocky bars of the river at low water. In the
neighbourhood of Boston it is more abundant than elsewhere. Mr. NUTTALL states,
that "they are killed in abundance on the shores of Cohasset, and other parts of
Massachusetts Bay, and are brought in numbers to the market of Boston, being
very fat and well-flavoured." "They arrive," he adds, "in flocks about the
close of August, and continue there, as well as in New Jersey, till the month of
September. In some instances solitary individuals have been killed in the
marshes of Charles river, in Cambridge, about the 22nd of July; these were in
company with flocks of small Sandpipers (T. Wilsonii), but whether pairs may
perhaps breed in the neighbouring marshes or not, we have not had the means of
ascertaining. While here, they feed on small coleoptera, larvas, and the common
green Ulva latissima, as well as some species of fucus or sea-weed, on which
they become fat. They utter a low plaintive whistle when started, very similar
to that of other species. Like the Snipe they seem fond of damp meadows and
marshes, and solitary individuals are often surprised by the sportsman in the
manner of that bird."
I have observed that the flight of the Pectoral Sandpiper resembles that of
the Knot, and is firm, rapid, and well sustained. It skims rather low over the
surface of the water or the land, and at times shoots high up into the air,
propelling itself with double rapidity and in perfect silence. It runs with
great agility, and probes the sand or wet earth, immersing its bill up to the
base. I never saw this species in any part of the interior. Its places of
resort during the breeding season, and the changes of plumage which it
undergoes, are unknown.
