The Flax Bird (Pyranga rubra) is the most numerous and best known of the two species we shall describe. Its length is six and a half inches, its breadth ten and a half inches, the wing being four inches long, and the tail two and a half inches. The coat of the male, when in its full beauty, is of a most magnificent scarlet, the upper portion of the feathers being of that colour, and white at their roots; the latter tint, however, is never visible during life, though very conspicuous after the bird has been stuffed. The wings and tail are of a brilliant black, affording a striking contrast to the glowing little body. Very shortly after the breeding season this plumage disappears, and is replaced by feathers resembling in their hues the quiet dress of the female; the upper part of the body being then of a greenish colour, and underneath of a pale yellow. This costume is followed after the moulting season by a third, when the male appears prettily spotted with bright red and green, and presents a most elegant appearance.
THE FIRE TANGARA.
The Fire Tangara, or Summer Red Bird (Pyranga æstiva), is larger than the rest of its congeners, measuring from six and three-quarters to seven and a quarter inches in length, and eleven across. The body is red, like that of the last-mentioned species, but the wings are of a reddish brown, and the whole plumage somewhat paler. The female is olive green, shaded with brown, the under part of the body being yellow, towards the middle shaded with red. Very old females are occasionally met with, resembling the male birds in their colours. The young are like the mother.
In their manners both these species of Fire Tangaras are much alike; they inhabit the extensive forests of America, where they are found in pairs, living a very quiet and retired life, and generally perching upon the topmost branches of the trees. The Summer Tangara receives its name from the fact that it is only seen in the United States from May to September; though far from numerous, it is well known all over the country, frequently making its appearance in the gardens and plantations, where it does considerable damage to fruit and flax. The scarlet species is generally seen as early as April, and leaves somewhat later than the Summer Tangara. The latter migrates by day, the former at night, the birds rarely consorting even on these occasions, and preserving their comparative isolation when flying through the length and breadth of the land. As to their habits, naturalists agree in telling us that they are quiet and monotonous; but, whilst constantly deploring their deficiencies as birds of song, they cannot speak too warmly of their great beauty and of the striking contrast their red plumage affords to the surrounding trees. Their flight is smooth and gliding; but they seldom descend to seek their food upon the ground; their movements among the branches are slow, and the trifling amount of animation of which they appear capable is expressed by occasionally flapping their wings, or uttering their call, which consists of only two notes. They live principally upon insects, catching them when upon the wing, and Wilson mentions having found Tangaras whose stomachs were entirely filled with the remains of bees. The nest, which is clumsy in its construction, is usually built upon a forked branch, no care being taken for its concealment. The Prince von Wied mentions having seen a brooding female that remained sitting quite undisturbed by his approach, even when he ventured quite close to the young family; indeed, so little precaution is taken to ensure safety, that the nests are often constructed by the roadside, and so lightly fastened to the branches upon which they are built as to be easily shaken from their place; dry roots and straw generally form the outer wall, the interior is lined with fine grass. The eggs, four or five in number, are light blue, or dark greenish blue, those of the Scarlet Tangara being spotted with different shades of purple. Both sexes unite in the duties of incubation, sitting upon the brood for the space of a fortnight, and feeding the nestlings principally upon insects. By the beginning of June the young birds are strong enough to fly about the country, accompanying their parents until the season for migration arrives. Wilson mentions a pretty instance that came under his own notice of the attachment of these beautiful creatures to their young. On one occasion, he tells us, he caught a young Scarlet Tangara that had been a few days out of the nest, and carried it to a distance of about half a mile, when he placed it in a cage near the nest of a Yellow Bird, thinking that as the occupant had a family of her own, she might take pity on the stranger. In this hope he was deceived, its plaintive cries being entirely disregarded, nor could it be persuaded to take food from his hand. He had almost decided on taking the poor bird to the place whence it came, when towards evening a Scarlet Tangara was seen flying round the cage and making every effort to obtain admission; not succeeding in its attempts, the bird flew away, speedily returning with a beakful of food; this continued till sunset, when it perched for the night upon a neighbouring tree. At break of day its ministrations recommenced in spite of all the enmity testified by its neighbour the Yellow Bird, who tried to drive it from the spot. Several days and nights were spent in this manner, the parent urging the young one by every tender persuasion of which it was capable to leave its prison and accompany her. At last the cage was opened, and the little captive permitted to rejoin its mother, who received it with loud demonstrations of affection and delight. The Tangara is but rarely seen in Europe, and though easily reared upon fruit and seeds, is by no means adapted for domestication.
Under the name of CALLISTES (Calliste) we include a considerable number of small birds, somewhat resembling the Siskin and Linnet in appearance, but much more varied and brilliant in their hues. Their beak is comparatively short, high, and slender, its edges compressed, the upper mandible furnished with a horizontal ridge, and the tips slightly bent. The eyelids are surrounded by a circle of small flat feathers; the wings and tail are of moderate length, the latter slightly forked and covered with small feathers; the legs are delicate, the tarsus high, and the toes short. The plumage of the Callistes is variegated, the tints on the coat of the male being more distinct and pure than in the female; the young resemble the parents, but are paler in colour. These birds inhabit the wooded districts of Brazil, and are distinguished from other Tangaras by the fact that they subsist entirely upon various kinds of seed.
THE RED-NECKED CALLISTE.
The Red-necked Calliste (Calliste festiva), the most prominent member of this group, is a small bird, five and a half inches long, the wing measures two and a half inches, and the tail two inches. Its shape is slender and elegant, the feathers extremely soft and delicate, and the coloration of the plumage exquisite; the front of the brow, cheek-stripes, base of the under mandible, chin, and upper part of the beak, are black; the upper portion of the forehead and small feathers round the eye, a beautiful greenish blue; the rest of the head is a brilliant ultramarine. Around the eyes and under the lower mandible runs a broad line of splendid cinnabar red, which passes over the cheeks, the region of the ear, sides of the throat and nape. The rest of the plumage is principally of a bright glossy green, shading into yellow on the hinder part of the body; the wings are brownish black, the feathers being edged with a broad green line, and the shoulder marked with a streak of orange. The feathers of the tail resemble those of the wings, but are shaded with green; the beak is deep black, the feet slate colour or reddish brown. The coat of the female resembles that of her mate; the colours, however, are somewhat paler, and a portion of the back is spotted with black.
These birds, which are by no means numerous, inhabit the woods upon the eastern coast of Brazil, and are occasionally found in Guiana. We are entirely ignorant as to their life and habits.
