Rh the female not only ascended the nest, but lay along it as before, with the same evident intention of receiving the male, and the same non-result.

At 5.30 a.m. I find the birds not working, but floating idly on the water. They are now side by side, each with the long neck drawn back, so that the head rises like a button from the centre of the back, making them look like pork- or game-pies floating about.

6.8.—Both now swimming to the nest, and when just off the bed of weeds where it is situated, first one and then another of them lies on the water, with the beak held down in a somewhat curious manner, as though minutely observing it, for the beaks point in its direction. It is the female who does this first, and I thought she wished to receive the male, for her attitude was just the same as when, upon the nest, she undoubtedly intended this. She soon desists, however, and it is then that the male assumes the same attitude, in which he continues longer.

At 6.30 the male goes again to the nest, and remains about it, but never going quite up to it, for some five or six minutes; then swims again to the female, who has not accompanied him. The interest taken by the male in the nest has been very marked throughout, more so even—in appearance, at any rate—than that of the female, though in the actual building of it she has been yet more efficient than he. He has always led the way to it, and yesterday—as noted—he continued building longer than she did.

6.54.—Male at nest as before, and begins now to dive and add to it. After a minute or two he ascends the nest, and I shall now—as hitherto—record exactly what I saw. After standing a little with straddled legs, he sinks down, and lies along the nest in just the same manner, as far as I can see, as the female has done, once before actual or attempted pairing, and many times, as prepared for and wishing it. The female is now swimming up, and, on arriving at the nest, she acts exactly as the male has done when contemplating ascending it in order to pair with her. Both in action, manner, and strongly implied intent the sexes seem to be reversed, yet there is no
