In passing along under the overhanging trees of the banks, we often saw the pretty turtle-doves sitting peacefully on their nests above the roaring torrent. An ibis* had perched her home on the end of a stump. Her loud, harsh scream of "Wa-wa-wa", and the piping of the fish-hawk, are sounds which can never be forgotten by any one who has sailed on the rivers north of 20 Deg. south. If we step on shore, the 'Charadrius caruncula', a species of plover, a most plaguy sort of "public-spirited individual", follows you, flying overhead, and is most persevering in its attempts to give fair warning to all the animals within hearing to flee from the approaching danger. The alarm-note, "tinc-tinc-tinc", of another variety of the same family ('Pluvianus armatus' of Burchell) has so much of a metallic ring, that this bird is called "setula-tsipi", or hammering-iron. It is furnished with a sharp spur on its shoulder, much like that on the heel of a cock, but scarcely half an inch in length. Conscious of power, it may be seen chasing the white-necked raven with great fury, and making even that comparatively large bird call out from fear. It is this bird which is famed for its friendship with the crocodile of the Nile by the name 'siksak', and which Mr. St. John actually saw performing the part of toothpicker to the ugly reptile. They are frequently seen on the sand-banks with the alligator, and, to one passing by, often appear as if on that reptile's back; but I never had the good fortune to witness the operation described not only by St. John and Geoffrey St. Hilaire, but also by Herodotus. However, that which none of these authors knew my head boatman, Mashauana, stopped the canoe to tell us, namely, that a water-turtle which, in trying to ascend a steep bank to lay her eggs, had toppled on her back, thus enabling us to capture her, was an infallible omen of good luck for our journey. * The 'Hagidash', Latham; or 'Tantalus capensis' of Lich. Among the forest-trees which line the banks of the rocky parts of the Leeambye several new birds were observed. Some are musical, and the songs are pleasant in contrast with the harsh voice of the little green, yellow-shouldered parrots of the country. There are also great numbers of jet-black weavers, with yellowish-brown band on the shoulders. Here we saw, for the first time, a pretty little bird, colored dark blue, except the wings and tail, which were of a chocolate hue. From the tail two feathers are prolonged beyond the rest six inches. Also, little birds colored white and black, of great vivacity, and always in companies of six or eight together, and various others. From want of books of reference, I could not decide whether they were actually new to science.
