The Cassicans hold pretty much the same place in America as that occupied by the Crows in European countries. In their habits they are lively and active, beautiful in appearance, and, though essentially occupants of trees, resemble the Yellow Birds in many particulars, like them frequenting fields of ripe corn, and doing considerable damage, without any apparent fear of the wrath of the proprietors. When in the woods, insects and seeds constitute their principal fare, and they will occasionally devour fruit. The voice of this species is not so pleasing as that of the Soffre, but it possesses very great flexibility—indeed, Schomburghk tells us that it can not only imitate the note of every other songster, but the cry of any animal, producing at times such a strange medley of sounds as to astound its hearers, who scarcely believe it possible that a single bird can alternately bleat like a sheep, crow like a cock, or scream like a turkey, all these various noises being accompanied by such extraordinary contortions of the whole body as cannot fail to excite laughter in those who witness this strange performance.

Scarcely less remarkable is the manner in which the Cassicans construct their nests. Like the Weaver Bird, they build regular settlements, suspending their artistically woven cradles in large numbers from the same tree, and very frequently in the immediate vicinity of other species. As with the Weaver Bird, these nests are inhabited from year to year, and repaired every season for the reception of a new family. In shape they are not unlike the large bags formerly used to carry shot, and are so lightly constructed that their walls may be seen through. Great patience and skill are exhibited in the manufacture of these abodes, some species only employing such materials as linen thread, or fibres, while others build with fine blades of grass, which they moisten with saliva in order to render them more pliable. Schomburghk tells us that this species is extraordinarily deficient in social attachment, and mentions an instance of this fact witnessed by himself. A large party of "Blackbirds" (Cassicans) had made their settlement upon the banks of a river which one day rose to an unusual height, and threatened destruction to the entire colony. Some of the nests were washed down, and others gradually filled with water. The terrified parents, unable to render any help to their young, flew about in an agonised confusion, or sought for their eggs and nestlings amongst the general débris, whilst such of the flock as were still above immediate danger sat quietly brooding, or continued their building operations without paying the slightest attention to the piteous cries of their companions. According to Audubon, these birds breed but once in the year, the nests being placed, as we have described, quite close together, thus ensuring a safety from the attacks of their numerous enemies, that could not otherwise be obtained; each family, however, leads a life quite distinct from that of its neighbours, and exhibits neither interest nor sympathy in the movements of those that live around it.

THE JAPU.

The Japu, or Tufted Cassican (Cassicus cristatus), is an inhabitant of South America, and has been selected for particular description as being one of the most remarkable species belonging to this group. In this bird the plumage is principally of a brilliant black, with the lower portion of the body of a deep reddish brown; the exterior tail-feathers are yellow, and the inner ones black. The beak is of a whitish yellow, the feet deep black, the eyes, like those of the rest of its congeners, light blue. The length of the male varies from fifteen and a half to seventeen inches, its breadth is twenty-three and a half inches, the wing measures from seven and two-third to eight inches, and the tail from six to seven inches. The female is at least three inches shorter, and the wings six or seven inches less in their span.

THE BALTIMORE BIRD.

We are indebted to the Prince von Wied for an exhaustive account of this species, from which we shall extract such particulars as our space will permit. This remarkable bird, he tells us, inhabits the whole of South America, but is most numerous in the northern portions, frequenting woodland districts, and such plantations or human habitations as may be in the immediate neighbourhood of forests, but avoiding barren or open parts of the country. It is social and active, flying about incessantly amongst the trees, and hanging suspended by its sharp claws from the branches, from time to time plucking a favourite fruit, and carrying it off with cries of delight to another spot where it may be eaten in safety. During the season, oranges and bananas constitute its favourite food, and large quantities of valuable fruit are thus destroyed, in spite of all the precautions taken by the planters for its preservation; but at other times the Japu contents itself with less dainty fare, and subsists principally upon insects and berries. Few scenes are more animated than that afforded by a settlement of these interesting birds, as they perch upon the branches of the forest trees, in parties of some thirty or forty couples, or fly about filling the whole air with their strange and varied song, the general effect of which, when thus heard in chorus, is far from unpleasing, though some notes are harsh, and others very shrill.
