The trees described in the preceding article as constituting the lodging place of the Pelicans, are frequented also, though less regularly, by a considerable number of these Boobies. They usually huddle together, in little groups, sitting closely side by side, so that four and five may frequently be brought down at a shot. I have invariably found the stomachs of those thus obtained, quite empty, and as the Frigate-birds assemble on the same trees, I conjecture that the Boobies examined had been compelled to disgorge the prey they had taken, by the assaults of their powerful neighbours: to avoid whose attacks, probably, they took refuge on the trees. As they sit, they frequently utter a loud croaking cackle. One which was disabled, manifested great ferocity, striking forcibly with the opened beak, endeavouring to pierce with its very acute points, as well as to cut with its keen saw-like edges. It had the sagacity to neglect a stick presented, and strike at the hand that held it; and my fingers could testify to the lacerating power of their formidable weapon. The tails of all the specimens that fell into my hands, were much worn at the extremity; probably from incubation on the rocks. The use of the very singular pectination of the middle toe, was indicated, by its being choked up in each one with down. The great length of the body in these birds is particularly observable when the integuments are removed. In one specimen, I found lying among the folds of the intestines, a tape-worm, about three feet in length. * * * * * The above is the only _Sula_ that we know anything of, about the coast of Westmoreland; but Mr. Hill has identified three others from the Pedro Kays, some of which appear to frequent the little Kays of the coast near Kingston. I believe they are the _Sula fiber_, or drab-coloured Booby, _S. piscator_, or White Booby, and _S. parva_, or Black and white Booby. Of this last Mr. Hill has a pair domesticated, of whose habits he has favoured me with the following pleasing notes.
