about with the greatest ease, and the slightest turn must be very effective. They would, therefore, often see quite plainly whilst appearing to us not to be noticing, and that the female should get the general effect of the male's display is all that is required by the theory of sexual selection—as conceived by Darwin. Darwin has expressly said that he does not imagine that the female birds consciously pick out the most adorned or best-displaying males, but only that such males have a more exciting effect upon them, which leads, practically, to their being selected. But though he has said this, it seems hardly ever to be remembered by the opponents of his view who, in combating it, almost always raise a picture of birds critically observing patterns and colours, as we might stuffs in a shop. However, having regard to the bower-birds, and especially that species which makes an actual flower garden, even this does not seem so absolutely impossible. The fact is, we are too conceited. With regard to the female bird sometimes, as here, keeping turned from the male while thus courted by him, this is, I think, capable of explanation in a way not hostile but favourable to the theory of sexual selection. At any rate, in both these instances, "il faut rendre a cela" either was, or seemed to be, the final conclusion of the female.
