quarrel together for the fish one has taken, or one pursues the other for the fish in its mouth. At

such times the interest of the spectators on the bridge increases to noisy shouting. The bird is provided with a sort of pouch or large throat, in which the small fish are entirely concealed, while the head or tail of the larger fish protrudes from its mouth. It is only at or near full tide that these birds are successful in catching fish under and near the bridges, as then the water is deep and comparatively still, and the fish seem to abound in the vicinity more than at low-tide. At such times there are frequently several rafts with Cormorants fishing near the bridges. The skill of the fisherman in propelling his craft, and the success of the bird in catching the fish are attested by the delighted curiosity and animated interest of the spectators."

The PELICANS (Pelecani), the largest and most striking members of this order, are at once recognisable by their enormous beak, furnished underneath with a capacious bag, and strongly hooked at its extremity. The upper mandible, which is remarkably depressed from its origin to its apex, is moderately broad, and rounded at the point; the culmen forms a conspicuous keel, running along the entire length of the upper jaw, and at its termination bends down to form the strong claw-like hook at the extremity. The lower mandible is exceedingly weak and slender, consisting of two long lateral branches, only joined to each other towards the apex, and enclosing between them a very capacious bag, formed by a dilatable expansion of the throat. In comparison with the above most characteristic features, the rest of the structure of the bird is to the ornithologist of secondary importance; it is, however, very peculiar. The body is large and cylindrical, the neck long and slender; the feet are small, toes long, and connected by a broad web. In the large broad wing, the third quill exceeds the rest in length; the tail, which is short, broad, and rounded, consists of twenty or twenty-four feathers. The plumage is thick, but remarkably hard and stiff; besides the almost naked sac beneath the throat, there is a considerable space around the eye completely denuded of feathers. The two sexes resemble each other very closely, but considerable differences serve to distinguish the old birds from the young.

Pelicans inhabit the torrid regions of the earth, but are also found to a considerable distance within the limits of the temperate zone. In their habits and mode of life, the different groups nearly resemble each other, and we shall therefore confine ourselves to a description of two species met with in Europe.

None but those who have travelled in Egypt and North Africa can form any idea of the vast numbers of fish-eating birds that there crowd the shores of every lake and river. Upon all the Egyptian lakes along the course of the Nile, during the period of its inundation, and still further to the south, along the banks of the Blue and White Nile, as well as on the shores of the Red Sea, Pelicans occur in such immense flocks that the eye is unable even to estimate their extent. Over a considerable surface of country they literally cover the quarter, or the half, of every square mile. When they are swimming out upon the lakes, they look like immense beds of water-lilies. When they come out of the water to sit upon the shore, more especially if it be upon one of the islands, and sit in the sunshine preening their feathers, they look at a distance like a vast white wall, and when they retire to sleep, all the trees upon the island are so thickly covered with them that they have the appearance of blossoms without a single green leaf. To meet a small flock of about ten or a dozen is an unusual occurrence, but to see hundreds or thousands together is a very ordinary spectacle. As the spring approaches, these enormous hosts are in some measure broken up. Many which during the winter season congregated together make their way to Southern Europe, where they breed, but numbers of them are left behind. In selecting the place of their sojourn, these birds seem to make no difference between salt water and fresh; they frequent both in almost equal numbers, but the depth of the water is to them a matter of considerable importance.
