The WHITE-TAILED TROPIC BIRD (Phaëton æthereus) is strikingly beautiful. Its head, neck, and under parts of the body are pure white, delicately tinged with red; the face is marked about the eyes with a broad stripe of black; the back and mantle are white, marked with a crooked dark line; the wings are black, bordered with white. The eye is brown, beak coral-red, foot dusky yellow. The length of this bird is two feet five inches, of this one foot five inches belongs to the centre tail-feathers; the breadth is three feet four inches. The White-tailed Tropic Birds are commonly met with upon the Atlantic Ocean, and, according to Latham, are found in abundance in the South Sea Islands, but are especially numerous in Palmerston Island, where the trees are frequently loaded with them. Ellis tells us that in the latter island they are so tame as to allow themselves to be taken from the branches with the hand. "These," says Bennett, "are amongst the most beautiful of all the oceanic birds, and excite admiration as the rays of a bright sun shine upon their chaste and delicate satin plumage; they are as gentle in manner as graceful in flight, and it is pleasing to watch their evolutions, for when soaring to a great elevation the action of their wings is slow, accompanied by a jerking motion, rising and falling in the air, at the same time uttering their peculiar, shrill notes. Sometimes they are resting on the surface of the water, and in calm weather occasionally seat themselves on the backs of turtles as they float along in lazy enjoyment."
Sailors formerly believed that the appearance of Tropic Birds indicated the contiguity of land; this idea, however, is erroneous, as they are frequently seen at a great distance from shore. According to Bennett this species has been seen 1,000 miles from the coast. The long tail-feathers of this beautiful bird are in great request.
THE RED-TAILED TROPIC BIRD.
The RED-TAILED TROPIC BIRD (Phaëton phœnicurus) has, like the preceding species, white plumage tinged with rose-colour; a broad, black, transverse band, which commences in front of the eyes, is prolonged towards the back of the head into a point; the centre of the secondary quills, and the feathers on the sides are deep black; the shafts of the primary quills are black nearly to the tips. The middle tail-feathers are white towards their base, but elsewhere bright red with black shafts. The eye is blackish brown, beak scarlet, with a pale blue stripe at its base, and the tarsus faint blue; the[Pg 221] feet are black. The length of this species is two feet four inches, breadth three feet; the longest tail-feathers are fifteen inches, and the rest five inches. The Red-tailed Tropic Bird is met with throughout the warm and temperate parts of the South Seas and Indian Ocean; during August and September it retires to breed upon the islands. The following description of the eggs and young was given to Mr. Gould by Macgillivray:—
"The eggs of the P. Phœnicurus are blotched and speckled with brownish red on a pale reddish grey ground, and are two inches and three-eighths long, by one inch four-eighths and a half broad. The contents of the stomach consisted of the remnants of cuttle-fishes."
THE WHITE-TAILED TROPIC BIRD (Phaëton æthereus). ONE-FOURTH NATURAL SIZE.
Latham states that these birds are found in great numbers in the Island of Mauritius, where they make their nests on the ground under trees. According to Bennett, "The nestlings have a singular appearance, resembling powder-puffs, being round as a ball and of a delicate snow-white colour; the plumage of the first year is white speckled with black, and they are deficient in the red shafts projecting from the tail, which do not make their appearance till the second year, when on the young bird moulting, the splendid and delicate roseate plumage is displayed."
The GANNETS (Sula) are larger but more slenderly built than the Tropic Birds. Their bill is longer than the head, and the upper mandible looks as though it were divided posteriorly into an[Pg 222] upper and an under portion, so that the beak has the appearance of consisting of three parts. The tarsi are diminutive but strong; the wings unusually long, with the first quill the longest; the tail consists of twelve feathers, and terminates in a wedge-like point. The face and throat are naked.
