 series of quick little bows, or, rather bobs, which he makes to his fiancée instead of one or more slower and much more imposing ones. Essentially, however, it is the same thing. The pace has been quickened and the interval lessened, whilst, to allow of the increased speed, the bow itself has been shorn of much of its pomp and circumstance, so that it has become, as I say, a mere bob. The turtle-dove may perform some half-dozen or more of these bobs, taking less time, perhaps, to get through them than do his larger relatives to achieve one of their solemn and formal bows. Still he is pompous too, he bends down low at the shrine, and though each little bob may not be much in itself, yet, when thus strung together, the display as a whole is equal to the other two.

All the time he is thus bowing or bobbing the turtle-dove utters a deep, rolling, musical note which is continuous (or sounds so), and does not cease till he has got back into his more everyday attitude. The hen looks sometimes surprised, sometimes as though she had expected it, and sometimes, I think,—but of this I am not quite positive—she will return the little series of musical bobs. This is in tree-land; but I have seen the turtle-dove court on the ground, and he then, between his bobbings, made a curious dancing step towards the female, who retired and gave her final answer by flying away.

Sitting a deux in some high tree, one of them will every now and again fly out of it, mount upwards, make one or two circling sweeps around and above it, then, after remaining poised for some seconds, descend on spread wings
