Now I have found a nest with the bird on it, to see and watch. It was on a ledge, and just within the mouth of one of those long, narrowing, throat-like caverns into and out of which the sea, with all sorts of strange, sullen noises, licks like a tongue. The bird, who had seen me, continued for a long time afterwards to crane about its long neck from side to side or up and down over the nest, in doing which it had a very demoniac appearance, suggesting some evil being in its dark abode. [Illustration: _Shag._] As it was impossible for me to watch it without my head being visible over the edge of the rock I was on, I collected a number of loose flat stones that lay on the turf above, and, at the cost of a good deal of time and labour, made a kind of wall or sconce with loopholes in it, through which I could look and yet be invisible. Presently the bird’s mate came flying into the cavern, and wheeling up as it entered, alighted on a sloping slab of the rock just opposite to the nest. For a little both birds uttered low, deep, croaking notes in weird unison with the surroundings and the sad sea-dirges, after which they were silent for a considerable time, the one standing and the other sitting on the nest _vis-à-vis_ to each other. At length the former, which I have no doubt was the male, hopped across the slight space dividing them on to the nest, which was a huge mass of seaweed. There were now some more deep sounds, and then, bending over the female bird, the male caressed her by passing the hooked tip of his bill through the feathers of her head and neck, which she held low down the better to permit of this. The whole scene was a striking picture of affection between those dark, wild birds in their lonely wave-made home. The male bird now flies out to sea again, and after a time returns carrying a long piece of brown seaweed in his bill. This he delivers to the female, who takes it from him and deposits it on the heap, as she sits. Meanwhile the male flies off again, and again returns with more seaweed, which he delivers as before; and this he does eight times in the space of one hour and forty minutes, diving each time for the seaweed with the true cormorant leap. Sometimes the sitting bird, when she takes the seaweed from her mate, merely lets it drop on the heap, but at others she places and manipulates it with some care. All takes place in silence for the most part, but on some of the visits the heads are thrown up, and there are sounds—hoarse and deeply guttural—as of gratulation between the two.
