to join them, he circles too, all three are circling, the light glinting on one, falling from another, thrown and caught and thrown again as if they played at ball with light."
I thought, therefore, that birds when they flew in pairs like this were disporting themselves together in a nuptial flight, and making—as indeed this, in any case, is true—a very pretty display of it. What was there, indeed—or what did there seem to be—to indicate that angry passions lay at the root of all this loveliness? But I had not taken sufficiently into consideration that sharp clap of the wings indicating a blow—a severe one—on the part of one of the birds with a parry on that of the other. This is how stock-doves, as well as other pigeons, fight on the ground, and it is as an outcome and continuation of these fierce stand-up combats—which there is no mistaking—that the contending birds rise and hover one over the other, in the manner described. My notes will, I think, show this, as well as the curious and, as it were, formal manner in which the ground-tourney is conducted.
"Two stock-doves fighting.—This is very interesting and peculiar. They fight with continual blows of the wings, these being used both as sword—or, rather, partisan—and shield.
