on that excursion. The other Terns were as new to me. I observed the
form of their black bill and feet, the yellow tip of the former, and wrapped
them up with care, while I tried to recollect the name they bore in books.
To have found hundreds of the Roseate Tern in the Floridas, while I had
anxious but slender hopes of meeting it on the coast of Labrador, was to me
quite astonishing. So it was, however, and I determined to ransack every
key and sand-beach, to try to find its breeding-ground. Nor were my
desires ungratified.
The Roseate Tern spends the breeding season along the southern shores of the Floridas in considerable numbers. At different times in the course of nearly three months which I spent among the keys, I saw flocks of twenty, thirty, or more pairs, breeding on small detached rocky islands, scantily furnished with grass, and in the company of hundreds of Sandwich Terns. The two species appeared to agree well together, and their nests were intermingled. The full number of eggs of the present species is three. They differ considerably in size and markings; their average length, how- ever, is an inch and three quarters, their breadth an inch and one-eighth; they are of a longish oval shape, rather narrowed at the small end, of a dull buff or clay colour, sparingly sprinkled and spotted with different tints of umber and light purple. They were deposited on the bare rocks, among the roots of the grasses, and left in fair weather to the heat of the sun. Like those of the Common Tern and other species, they are delicious eating. The eggs of the Sandwich Tern were more attended to during the day, but toward night both species sat on their eggs. I did not see any of the young, but procured a good number of those of the preceding year, which kept apart from the old birds, but had in all respects the same habits.
The Roseate Tern is at all times a noisy, restless bird; and on approaching its breeding place, it incessantly emits its sharp shrill cries, resembling the syllable crdk. Its flight is unsteady and flickering, like that of the Arctic or Lesser Tern, but rather more buoyant and graceful. They would dash at us and be off again with astonishing quickness, making great use of their tail on such occasions. While in search of prey, they carry the bill in the manner of the Common Tern, that is perpendicularly downward, plunge like a shot, with wings nearly closed, so as to immerse part of the body, and immediately reascend. They were seen dipping in this manner eight or ten times in succession, and each time generally secured a small fish. Their food consisted of fishes, and a kind of small molluscous animal which floats near the surface, and bears the name of "sailor's button." They usually kept in parties of from ten to twenty, followed the shores of the sand-bars and keys, moving backwards and forwards much in the manner of the Lesser
