usually loud when the bird was hungry, and doubly so at the moment when food was presented to it, as, in its ravenous eagerness to seize, it frequently missed from its hurried motion. Sometimes, when its belly was full, it substituted a quivering whistle, in a very high key, emitted, I believe, through the nostrils. The fæces were very fluid, and resembled a thin solution of lime; they left a chalky deposit, pulverulent: and were not at all fœtid. It seemed to have no desire for drinking. On the 1st of November it died, having been in my care about a fortnight. Soon after this, my lad Sam being again near the _Spanish-hole_, looked in, and discerned the old Owl sitting on the same spot, and on the 12th, I again visited it. On peeping cautiously over the wall, I discerned her on the rock, and fired; but merely wounding her, she retreated into one of the cavities, so that Sam, on descending, could not find her. There were four eggs, which were placed close together, but in no nest. Another Owl, doubtless the mate, flew at the report of the gun from somewhere near the margin, opposite to the female’s side: but though we made considerable noise in entering the area, and in talking, the boy in descending discovered him perched still near the margin of the cavern. At length, however, he flew off. As the sitting bird had concealed herself, and could not be found, I determined to leave the eggs untouched, presuming she would soon return to them. In the course of half-an-hour I returned, and had the satisfaction of seeing her again on the eggs: I fired, and this time not vainly. In her fall she crushed one of the eggs, which had evidently been in contact with the skin of her abdomen, that part being wholly denuded of feathers. The remaining eggs were advanced towards hatching in _very different degrees_, and one was found on dissection in the oviduct of the bird, completely shelled, and ready for deposition. The yolk of this was small in quantity, and of a pale yellow tint. Other eggs in the ovary were from the size of large shot downward.
