This species, like the Piping Plover, _Charadrius melodus_, forms no nest; and whilst the latter scoops a place in the sand for its eggs, the Ring Plover forms a similar cavity in the moss, in a place sheltered from the north winds, and exposed to the full rays of the sun, usually near the margins of small ponds formed by the melting of the snow, and surrounded by short grass. Some of these pools are found on the tops of the highest rocks of that country. The eggs, like those of all the family, are four, and placed with the small ends together. They are broad at the larger end, rather sharp at the other, measure 1-1/4 inch in length, 7-1/8 inches in their greatest breadth, are of a dull yellowish colour, irregularly blotched and spotted all over with dark brown of different tints. The young are at first of a yellowish-grey colour, prettily marked with darker spots on the shoulders and rump. As soon as their parents dismissed them, they were observed searching for food among the drying cod-fish, and along the beaches. By the 12th of August, all the individuals which had bred in Labrador and Newfoundland, had taken their departure, migrating southward in company with the Phalaropes and Schintz’s Sandpipers. Many of these birds proceed by our great lakes and rivers, they being sometimes seen in September along the shores of the Ohio and Mississippi. At this period they are now and then observed on ploughed lands, where they appear to procure different species of seeds and insects. Along the whole extent of our Atlantic shores, they are numerous at this season, and great numbers are killed, the flesh of the young birds especially being juicy and tender. The flight of this species is swift and sustained. They are fond of associating with other birds of similar habits, and are generally unsuspicious, so that they are easily approached. When on wing, their notes are sharp, sonorous, and frequently repeated. The young members of my party were often much amused by witnessing our pointer chasing the old birds, whilst the latter, as if perfectly aware of the superiority in speed, would seem to coax him on, and never failed to exhaust him by flying along the declivities of the rocks up to their summits, and afterwards plunging downwards to the base, thus forming great circuits over a limited range. Their food consists of small crustacea, mollusca, and the eggs of various marine animals. The old males are very pugnacious in the breeding season, and engage in obstinate conflicts, drooping their wings, and trailing their tail fully spread out in the manner of some species of Grouse on similar occasions.
