 show a preference for one male over another, and also (though of this I cannot be so sure), a power of dismissing birds from her. But if she really possesses such a power, she cannot very well assert it when closely pressed upon by a crowd of admirers. I noticed, too, and thought it curious, that a female would often approach a male bird with her head and neck laid flat along the water as though in a very "coming-on disposition," and that the male bird declined her advances. This, taken in conjunction with the actions of the females when courted by the males, appears to me to raise a doubt as to the universal application of the law that throughout nature the male, in courtship, is eager and the female coy. Here, to all appearance, courtship was proceeding, and the birds had not yet mated. The female eider-ducks, however—at any rate some of them—appeared to be anything but coy. As time went on and the birds became paired this curious note of the males became less and less frequent, and at last ceased, a proof, I think, that the note itself is of a nuptial character, and also that the birds at the time they kept uttering it were seeking their mates.

I regret that I was not able to observe the further breeding or nesting habits of these interesting birds. A few of the females may have laid before I left the island, but the greater number were still on the water. One day I put one up from the heather, upon which I lay down and waited. Soon a pair of them—both females—flew round me and alighted together not far off. Both then lay or crouched in the heather at a few yards from each other. Later, whilst watching from the coast, I saw two female eiders walking side by side
