Tern, and wherever a shoal of small fish was found, there they would hover
and dash headlong at them for several minutes at a time.
The wreckers informed me that this species returns regularly to these islands each spring, about the 10th of April, and goes off southward early in September. These birds, with their favourite companions the Sandwich Terns, habitually resorted to the sand-bars each day, to rest for an hour or two. I have never seen them on any part of our middle or eastern coast, and am of opinion that they rarely proceed farther eastward than the Capes of Florida, and that they are more attached to the immediate vicinity of the shores than the larger species, which more generally fly out to some distance. The delicate and beautiful rosy tint of the breast soon fades after death. Those specimens which were not skinned immediately after being procured did not retain it for a week, and in none of them was it perceptible, without separating the feathers, at the end of a month. In winter it disappears, as well as the glossy black of the head. The length of the outer tail-feathers varies considerably; but I could perceive no decided difference of size or colour in the sexes, although I thought the females somewhat smaller than the males.
