The YELLOW STARLINGS (Icteri) are birds varying in size from that of a Crow to that of a Finch. Their bodies are elongated, but powerfully built, the beak conical, the wings and tail of moderate length, the tarsi strong, and the plumage soft and brilliant, black, gold, or red preponderating in its coloration; the beak is rounded and thick towards its base, and without any notch or hook at the apex, its upper portion being prolonged like a shield among the feathers of the forehead. The fourth quill of the wings is longer than the rest; the tail, which is half covered by the wings when the bird is at rest, is rounded or graduated towards its extremity; the tarsi are longer than the middle toes, and covered in front with scaly plates; the toes are of moderate length, armed with strong, bent, and pointed nails. In some species the feathers on the top of the head take the form of a tuft, and in others the cheeks are left bare. All the members of this group are social, cheerful, and active; some of them are rich in song. Their favourite haunts are in the woods, where they subsist principally upon insects, snails, fruit, or seeds. Their nests are built with care, and display considerable artistic skill.
THE BOBLINK (Dolichonyx oryzivorus).
The TROOPIALS (Agelaii) include the smallest members of the last-mentioned group. In these birds the roof of the beak is quite straight, and its margins bent at an angle towards the gape; the hinder toe is furnished with a spur-like claw. The plumage of the young differs considerably from that of the parent birds, and is very various in its colours and markings.
THE RICE-BIRD.
The Boblink, or Rice Bird (Dolichonyx oryzivorus), possesses so many features in common with both Finches and Starlings as to render it difficult to decide amongst which it should really be placed. This species is very numerous in North America, where it is much detested on account of the serious damage it does to the fields of ripe grain. The principal characteristic of the group of Rice Eaters to which this bird belongs is their strong, conical beak, which is of moderate length, and much compressed towards the sides, the upper mandible being narrower than the lower portion, and lying, as it were, enclosed within its edges. The body is compact, the head large, the wings of moderate size, the second quill being longer than the rest; the tail is of great length, and each individual feather composing it terminates in a sharp point; the feet are not large, but powerful, and the plumage compact and glossy. The body of the Boblink measures seven inches, its breadth being about eleven inches, the wing three and a half, and the tail two and a half inches. The plumage varies considerably at different seasons of the year. During the period of incubation the male is black upon the head, the lower portion of the body, and the tail; the nape is brownish yellow, and the feathers upon the back black, with a broad yellow margin; the shoulders and rump are of a yellowish white; the wing-covers and quills are black, bordered with yellow. The eye is brown, the upper mandible dark brown, and the lower one blueish grey; the feet are light blue. The female is smaller than her mate, of a pale yellowish brown upon the back, the shafts of the feathers being marked with a dark tinge; the lower parts of the body are of a pale greyish yellow, the sides streaked in the same manner, as is the back; the bridles are brown, and a yellow line passes over the eyes; the quills and tail-feathers are much lighter than in the gala dress of her mate. During the winter months the male bird wears a coat closely resembling that of the female. The young are similar to the mother, but all their tints are greyer and paler.
When upon the ground, the movements of this species may be described as being more like a step than a hop; its flight is light and graceful, and its powers of climbing amongst the stubble by no means inferior to those of the Reed Sparrow. The Boblink (so called from its well-known cry) appears regularly in North America during the summer months, visiting the West Indies and the northern parts of South America in the course of its migrations. About May these birds begin to make their appearance in New York by small parties, which gradually increase in numbers until they literally swarm throughout the whole State—indeed, Audubon tells us that it would be impossible to find a field unoccupied by these destructive visitors. Even the breeding season does not interfere with their social relations, for the nests are built near together upon the ground, each pair, however, keeping possession of a distinct territory, in the centre of which the little home is made with much art, amidst the grass or stubble. The cares of the brood devolve entirely upon the females, their mates, meanwhile, disporting themselves over the neighbouring fields, and making the air resound with their endeavours to rival each other in the beauty of their song, which is so rich and varied in its tones as frequently to lead the hearer to imagine that he is listening to the voices of many singers, when in reality the sounds are produced by a solitary bird. Wilson describes the performance of the Boblink as resembling a series of notes struck upon all parts of the pianoforte in rapid succession, and tells us that the effect, though strange, is extremely pleasing. When perched, the male accompanies its song by a variety of animated gestures and movements of its wings. The eggs are laid about the end of May; they are from four to six in number, white, and thickly marked with dark blue or black spots irregularly distributed. Each couple breeds but once during the year. The young are fed upon insects: they rapidly attain their full size, and are ready to join their parents in the work of destruction about to commence. No sooner is the period of incubation over than the nature of these birds seems to undergo an entire change. The male completely loses his song, and doffs his brilliant coat, which is replaced by a comparatively quiet dress, resembling that of the female, and all exchange their hitherto harmless demeanour for a life of active and really formidable mischief. In vain are every means adopted by the inhabitants to scare the destructive flocks from their fields of young corn; hundreds of thousands are shot, but with little result beyond driving the enemy from one district to take refuge in another, and it is only when the work of devastation has been fully carried out that these enormous swarms leave the locality to carry on their terrible raids in another part of the country. It would seem as though the hatred with which the farmers regard this bird had made them entirely overlook the service it renders them during other seasons of the year by the enormous quantities of insects it consumes; even the great beauty of its song has not induced them to tame it.
The MARSH TROOPIALS (Agelaius) are quite as numerous, and almost as destructive as the members of the last-mentioned group. In these birds the beak is long, conical, very pointed, and slightly compressed, the body powerful, the wings of moderate size, their second and third quills being longer than the rest; the tail moderate, rounded at its extremity, and the plumage soft and glossy.
