But finally I fixed its place in the avian schedule with the help of my field glass white under parts, slightly tinged with yellow, back and rump olive green, top and sides of head delicate bluish-ash; no eye-ring, no wing-bars. There is no other warbler marked quite like that.

A cock-chaffinch up in the limes saw her, and condescending at last to break his song, described a flashing streak of wine-red breast and white wing-bars in the sun. He appeared to recognize her sinister yellow shield in time, however, and returned to his perch with a flourish, leaving the wasp to go on and begin dancing up the wall of the house till she came to the open window.

The shining, silken, iridescent dark green of the head and neck; the snowy, sharply defined, narrow collar of white, dividing the green of the neck from the brownish ash of the back and the gorgeous chestnut of the breast; the delicate pure grey of the belly finely pencilled with black lines; the rich, glossy purple of the broad wing-bars shot with green reflections; the jaunty, recurved black feathers of the tail; the smart, citron-yellow of the bill and feet; all these charms were ample excuse for his coxcombry and continual posings.

In many groups of birds the plumage is differently coloured in the several species, yet certain spots, marks, or stripes are retained by all. Analogous cases occur with the breeds of the pigeon, which usually retain the two wing-bars, though they may be coloured red, yellow, white, black, or blue, the rest of the plumage being of some wholly different tint.

In these cases we have feathers symmetrically shaded, like those which give so much elegance to the plumage of many natural species. I have also noticed a variety of the common pigeon with the wing-bars symmetrically zoned with three bright shades, instead of being simply black on a slaty-blue ground, as in the parent-species.
