While one might say these birds, the green porcelain, the small black bird and their two amigos,  more easily seen below, are if not in hand then at hand, they are also in, or at least proximate to, the bush, in this case cherry blossom. The duality of birds being neither here nor there,  there being more than two, the blossom being at its optimal pink poised  position, ready to float down if ruffled, is one way of looking at things.  Wallace Stevens moments everywhere.
