As closely allied to the Purple Martin, in manners, as in form and colouring, I long mistook the present bird for that well-known species, as I think others have done also. The white belly is, however, a sufficient mark of distinction. It is very common, at least in the lowlands and inferior mountain ranges, during the summer; some remain with us through the winter, but as there is a very marked diminution of their numbers, I conclude that a large body of them migrate on the approach of that season, probably to Central America. About the end of March we see them in great numbers, assembled early in the morning on the topmost branches of the lofty cotton trees, which at that season are leafless. On these they crowd so closely, side by side, that I have known five to be killed at one discharge. In the autumn we observe exactly the same habit. Perhaps we may trace some analogy here to those periodical congregations of other species which are known to be connected with migration.

It is a remarkable fact, that of the seven species of Swallows and Swifts which summer in North America, all of which are stated to migrate to the southward before winter, not one should have occurred to me in Jamaica. Although every day through the winter months, my almost undivided attention was given to birds; and though from August to April about thirteen hundred specimens of birds fell into my hands, more than one thousand of which were shot by myself and my servants, not a single individual of a North American species was observed among them. I simply state the fact, leaving any one to draw his own inferences.

At the same time, I should observe, that Mr. Hill thinks that Acanthylis pelasgia visits Jamaica in its periodical migration. Referring to an incident which he had mentioned to me before, he says, “The migratory hirundines, whose squadrons moving in circles, I gave you a sketch of in March last, as seen by me at that time passing over us from south to north, (and I have observed them yearly either in that month or in April,) I conclude to be flocks of pelasgia on their passage to their summer homes northward, after wintering in the tropics. The circular movement of the migratory retinue; the direction of their flight; their known wintering on the neighbouring intertropical shores; their association at all times in multitudinous numbers; and the cry with which they announce their passage, as they leisurely course round,—tsippee, tsippee, tsippee, seem to me so many identifications of this species.”

The Blue Swallow has the same propensity to bring up his family in darkness, as his purple brother. The stipe of an old palm, whose porous centre decays, while the iron fibres of the exterior remain strong, is his ordinary resort. At the beginning of April, I observed several pairs flying in and out of holes, bored I suppose by the Woodpecker, in the stipe of a dead Cocoa-nut still tall and erect, but a mere leafless post, tottering in the breeze and ready to fall. At the middle of May, Sam observed several pairs entering a round hole, about two inches in diameter, beneath the eaves of Belmont house.

Near the end of June, when on my way in a coasting boat from Bluefields to Kingston, I was lying wind-bound in Starvegut Bay. There the inhospitable shore is strewn with immense fragments of limestone rock, honey-combed and fretted into holes, through which the surf breaking furiously, finds vent in perpendicular jets and spouts of water, or in columns of spray resembling steam from an engine-pipe, accompanied with crashing roar. Yet I observed with interest, that the Blue Swallows were frequenting these rocks, and I noticed one repeatedly going in and out of a small hole near the summit of a rugged mass, separated from the shore, and completely isolated by the boiling surf. Lansdown Guilding, in some notes on the Zoology of the Caribbean Islands, (Zool. Jour. III. 408,) observes, “We have but few of this family in St. Vincents: among them is a Swallow, which roosts, and I believe builds, in the rock of the sea-shore. It is curious,” he adds, “to observe the bird in calm weather skimming patiently along the sea in search of insects, evidently ignorant of the fact that they are confined to fresh water, and do not sport on the surface of salt waters.” I cannot agree, however, with this accomplished naturalist here: that the Swallows do occasionally skim over the sea, is undeniable; and that gnats and other minute insects are also in the habit of frequenting the salt water, though not in such numbers as over the fresh ponds and rivers, is no less certain, at least in Jamaica.
