Dromiceius Nov? Hollandi?. Vieill.
The New Holland Emeu, as well as the Ostrich and the Cassowary, to both of which it is nearly related, is now generally regarded as belonging to the Rasorial Order, the Gallina? of Linn?us, the feet of which are formed for running and for scratching up the earth in search of the seeds which constitute their usual subsistence. Some of the birds, however, which are referred to it, and particularly those now under consideration, feed upon fruits and roots. The whole of the Order are distinguished by a certain degree of convexity on the upper surface of the bill, the base of which is enveloped by a membrane, in which are situated the nostrils covered by a cartilaginous[222] scale; by the muscular plumpness of their bodies, and especially of their legs; by the shortness of their wings, and the diminution of strength in their pectoral muscles; and by the thickness and strength of their anterior toes, generally three in number, united at the base alone by a connecting membrane, and roughened beneath. These characters conjoined sufficiently indicate that their proper place of abode is the surface of the earth, on which they are enabled to run with a greater or less degree of speed; and that the air, in which they are incapable of elevating themselves to any considerable height, or of propelling their flight with more than moderate swiftness, and into which some of them cannot even raise themselves at all, is an uncongenial element to which they can seldom resort. They furnish the principal and most useful breeds of our domestic poultry, and stock our farm-yards with their most valuable inhabitants.
The distinctive generic characters of the New Holland Emeu, which forms part of the Ostrich family, and is, with the sole exception of the Ostrich, the largest bird known to exist, consist in the flattening of its bill from above downwards, instead of from side to side; in the absence of the bony process which crests the head of the Cassowary, of the wattles which depend from his neck, and of the long spurlike shafts which arm his wings; and in the equal, or nearly equal, length of all his claws. The Emeus, however, agree with the Cassowaries in the number of their toes, three on each foot, all of them directed forwards and extremely thick and short, the posterior toe, which is common to most of the Order, being in them entirely wanting; in the excessive shortness[223] of their wings, which do not even, as is the case with the Ostriches, assist them in running, much less in flight, of which, in common with the latter, they are absolutely incapable; and in the structure of their feathers, which are for the most part double, each tube being divided near its origin into two shafts, the barbs of which are soft, downy, and distinct from each other, and assume at a distance rather the appearance of a silky covering of hair than that of the common plumage of birds.
The New Holland bird has the head and upper part of the neck thinly covered with slender black feathers; the space around the ears alone being left bare, and exhibiting, as well as the neck and throat, which are but partially concealed by the scattered plumage with which they are provided, the blue tinge of the skin. The general colour of the plumage is grayish brown above, with a more plentiful intermixture of the gray and a consequent lighter tinge beneath. The young are striped longitudinally with brown and gray. Their bill is black, and their legs are remarkably thick and of a dull brown. The great length of the latter and of the neck, and the erect attitude and quiet demeanour of these birds, which sometimes attain as much as seven feet in height, give them altogether a noble and imposing appearance. They were formerly common in the neighbourhood of Botany Bay, subsisting, like the rest of their tribe, upon vegetable substances, chiefly fruits. They are extremely wild, and run with great swiftness when pursued, outstripping it is said the fleetness of the greyhound. Like the Kanguroos, they are sometimes hunted by the colonists as articles of food; and their flesh is stated to have[224] much of the flavour of beef. The quantity of provision supplied by one of these birds is by no means inconsiderable.
The animals of the part of New Holland from which these birds are derived appear in general to suffer little from their transportation to the climate of England. The Emeus, like the Kanguroos, have become to a certain extent naturalized in the Royal Park at Windsor, where they breed without difficulty and with no extraordinary precautions. Here they have assigned to them a sufficient space of ground to take ample exercise; and this circumstance contributes not a little to the thriving condition in which they are met with. They are perfectly harmless unless when irritated or pursued, in which case they sometimes strike very severe blows with their beaks, which are extremely hard. The pair in the Tower were obtained from this establishment, where they were bred.
