The Spotted Sandpiper has a wonderfully extensive range, for I have met with it not only in most parts of the United States, but also on the shores of Labrador, where, on the 17th June 1833, I found it breeding. On the 29th of July, the young were fully fledged, and scampering over the rocks about us, amid the putrid and drying cod-fish. In that country it breeds later by three months than in Texas; for on the head waters of Buffalo Bayou, about sixty miles from the margin of the Mexican Gulf, I saw broods already well grown on the 5th of May 1837. On the same day of the same month in 1832, a similar occurrence happened on an island near Indian Key, on the south-east coast of Florida. In Newfoundland, on the other hand, the young were just fully fledged on the 11th of August 1833. It appears strange that none were observed by Dr RICHARDSON on the shores of Hudson’s Bay, or in the interior of that country. They are quite abundant along the margins of the Mississippi, the Ohio, and their tributaries, where they remain until driven off by the cold, and return about the beginning of April, at which period the Purple Martin also makes its appearance. In our Middle Districts, they arrive a fortnight later. On the Island of Jestico, in the Gulf of St Lawrence, about twenty pairs had nests and eggs on the 11th of June; and the air was filled with the pleasing sound of their voices while we remained there. The nests were placed among the tall slender grass that covered the southern part of the island. They were more bulky and more neatly constructed than any that I have examined southward of the Gulf of St Lawrence; and yet they were not to be compared with those found in Labrador, where, in every instance they were concealed under ledges of rocks extending for several feet over them, so that I probably should not have observed them, had not the birds flown off as I was passing. These nests were made of dry moss, raised to the height of from six to nine inches, and well finished within with slender grasses and feathers of the Eider Duck. As usual however, the eggs were always four, when the bird was sitting. They measure an inch and a quarter in length, by an inch at their thickest part, so that they have a shortish and bulky appearance, though they run almost to a point. They are smooth, and handsomely marked with blotches of deep brown and others of a lighter tint, on a greyish-yellow ground, the spots being larger and closer towards the rounded end. Both sexes incubate, and remain with their brood until the time of their departure.
