 year when peewits are only beginning their nuptial antics, though, as to their having begun them, there is no doubt, as I had carefully noted this at a still earlier date. But long subsequent to this, and when the theory of a not fully developed state of the sexual feelings could no longer be tenable as an explanation of non-combativeness, I noticed, or thought I noticed, a more than usual tendency in this species for a single bird to project itself, so to speak, into the midst of a married pair, and for its presence not to be resented, but rather otherwise. If this be really so—for, of course, I may be deceived—it is interesting, and perhaps assists the suggestion which I have offered as to the origin of the astonishing conduct of the spur-winged lapwing, the two being such near relations. When the habit had once commenced, it might continue and become fixed, irrespective of season.

But it may be said that all the evidence which I here bring forward is of three birds being together, and that there is none as to any sport or antic, of however incipient or rudimentary a nature. I have, however, often seen peewits sport and wanton in the air in threes, but I admit that more evidence in this direction is wanted.

The first of these is that attractive and delightful little creature, the dabchick or little grebe (Podiceps fluviatilis), a bird whose society I have always cultivated to the best of my ability. My first note, taken on 14th December, I give merely by way of showing that sexual feelings in birds may not always lie entirely
