The Rollers (Coracias garrula), [Fig. 220], have in their general appearance and habits considerable resemblance to the Jays; but they differ from the beak being more robust, and the nostrils uncovered; they are also more timid, withdrawing into the thickest parts of the woods, which are their favourite haunts. When taken young from the nest it is tameable. Dr. Meyer, of Offenbach, and others, have succeeded in rearing them; but although they become so tame as to know those who attend to their wants, they never grow familiar. Their favourite food consists of insects and their larvæ, worms, and the smaller reptiles; but in their absence they feed on berries, seeds, and certain roots.
The bill of the Roller is black towards the point, becoming brown at the base, with a few bristles; the irides are formed of yellow and brown circles; the head, neck, breast, and belly present various shades of bluish verditer, changing to a palish green; the plumage of the upper part of the body is a brilliant azure blue on the shoulders, and reddish brown on the back; rump feathers purplish. Wing primaries dark bluish black, lighter on the edge; tail feathers pale greenish blue. They abound in Europe, Africa, and Southern Asia. Although the natural habitat of the bird is oak and beech forests, M. Vieillot tells us that in Malta, where trees are scarce, the bird nests on the ground. In Barbary it has been observed to build on the banks of the rivers, and Pennant observes that where trees are wanting it builds its nest in clayey banks.
Fig. 221.—Starling (Sturnus vulgaris, Swainson).
The Starlings (Sturnidæ) are characterised by a straight bill, depressed towards the point. They are remarkable for their vivacity, and grave, sombre plumage, lit up with brilliant metallic reflections of green and blue. They are sociable birds, living in numerous flocks, being, says Selby, "particularly abundant in the fenny parts of Leicestershire and Nottinghamshire, where they roost among the reeds. Before retiring to rest they perform numerous manœuvres in the air, the whole colony frequently describing rapid counter-flights round a common centre. They will sometimes continue repeating the eccentric evolutions for half an hour before they finally settle for the night." Their favourite food is seeds and berries, and occasionally insects, worms, and small terrestrial mollusks. They choose for their nests well-protected places, such as the hollows of decaying trees, crevices of walls, the belfries of old churches, the ledges of roofs, and sometimes even the interior of pigeon-houses. The nest is formed of dry grass, in which it lays five light blue eggs. The Starling is accused of seeking the shelter of the dovecot for the purpose of sucking the inhabitants' eggs, but this is now found to be a calumnious error." They are diffused over all quarters of the globe. There are two species described among European birds—Sturnus vulgaris (the Common Starling), and Sturnus unicolor (the Sardinian Starling), which is black, and without spots, with the anterior feathers very long, tapering, and drooping from the base of the neck. It is found in Algeria among the rocks, where it builds. It passes the winter on the African coast of the Mediterranean, in company with the Common Starling. Its flesh is bitter, and consequently unpleasant to the taste, but it is sought after for its docility, and for the ease with which it is taught to speak.
Fig. 222.—The Pensile or Baltimore Oriole (Icterus baltimorus, Wood).
The Baltimore Orioles (Xanthornis baltimorii, Sw.) have the bill broad at the base, nearly conical and pointed; the upper mandible has the dorsal line slightly arched, the ridge narrow, the sides flat and sloping at the base. They are chiefly American birds, and have considerable resemblance in form and habit to the European Starlings. Like them, they are sprightly, light, and very rapid on the wing, live together in large flocks throughout the year, feeding on seeds, berries, and especially insects, and frequently committing ravages on cultivated fields and orchards. Some of this genera exhibit remarkable industry and skill in the construction of their nests: the most ingenious represents a kind of purse, about a yard in length and a foot in diameter, the mouth or entrance being placed sometimes at the upper extremity, sometimes on the side. Naturalists have subdivided them into many smaller groups or genera, the most important being the one here described, and which may well be taken as an example. They are confined entirely to North America.
