AMERICAN RING PLOVER. _CHARADRIUS SEMIPALMATUS_, BONAP. PLATE CCCXXX. MALE AND YOUNG. I have had great pleasure in observing the migrations of this species, particularly in early spring, when great numbers enter the southern portions of the United States, on their way northward, where it is now well known to breed. At that period, whatever attempts you may make to prevent their progress, they always endeavour to advance eastward; whereas in early autumn, they will rove in any direction, as if perfectly aware that, the task imposed upon them by Nature having been accomplished, they may enjoy their leisure. Those which pass the winter within the limits of the Union, are mostly found along the shores of South Carolina, Georgia, the Floridas, and as far south as the mouths of the Mississippi; there being no doubt that many remain on the coasts of the Gulf of Mexico, as I have found some there early in spring, before observing those which I knew by their manners to be recently arrived. In the course of my late visit to Texas, I found them on Galveston Bay, where I observed some arriving from the westward.
