THE FRIGATE BIRD.
The Frigate Bird is principally characterized by a strong, robust bill, longer than the head, with mandibles hooked at the point; the front of the neck bare of feathers; wings very long and narrow, first two feathers longest; tail lengthy and forked; feet short; toes united by a membrane deeply notched.
The Frigate Bird has a most expansive spread of wing; its power of flight is, therefore, very great. It inhabits the tropical seas of both the Old and New World; and navigators assure us that they have met with it many miles from any shore. When a hurricane arises they mount up far above the storm, and remain in those empyrean regions until it is again fine weather. In consequence of their almost disproportionate spread of wing, they can sustain themselves in the air for lengthened periods, without taking or requiring rest.
Their sight is so piercing that, at a distance far beyond that which would render them invisible to us, they can perceive their prey, the principal of which is the Flying-fish. From their elevated situation, they dart down upon their favorite food, which has relinquished its native element; and, keeping their neck and feet in a horizontal position, cleave asunder the air and grasp their victim, who little expected to meet with an enemy in the element which it sought for safety. It is no unusual thing for it to rob the Gannet of the Fish which it has just caught; the unfortunate Bird acting as purveyor to this sea-robber.
The Frigate Bird is of such a combative temperament, and has such an unbounded confidence in its strength, that it is not afraid of Man. It has been known to dash at a sailor, and to snatch at the Fish which he held in his hand. M. de Kerhoent, a French navigator, relates that, during a residence at the Island of Ascension, a perfect cloud of Frigate Birds surrounded his crew. They hovered about a few feet above the coppers of the open-air kitchen, in order to carry off the meat, without being intimidated in the least by the presence of his followers. Some of them approached so near, that M. de Kerhoent knocked down one of the impudent intruders with a blow of his stick.
They assemble in large flocks on the islands where they are accustomed to breed. In the month of May they begin to repair their old or construct new nests. They pluck off with their beaks from the bush small dry branches, and with these pieces of stick crossed and re-crossed, a foundation is formed. These nests are situated upon trees which hang over the water, or are placed on rocks overjutting the sea; in them they lay one egg of a pure white color.
