If, during the breeding-season, a strange male attempts to enter the burrow, he is attacked; the female does not remain passive, but closes the mouth of the burrow, and encourages her mate by continually pushing him on from behind; and the battle lasts until the aggressor is killed or runs away. Quoted from Fischer, in 'Dict. Class. d'Hist.
Spiza cyanea, during the breeding-season, is of a bright blue colour; and though generally peaceable, it attacked S. ciris, which has only the head blue, and completely scalped the unfortunate bird. Mr.
When the sexes differ in beauty or in the power of singing, or in producing what I have called instrumental music, it is almost invariably the male who surpasses the female. These qualities, as we have just seen, are evidently of high importance to the male. When they are gained for only a part of the year it is always before the breeding-season.
Even with the most pugnacious species it is probable that the pairing does not depend exclusively on the mere strength and courage of the male; for such males are generally decorated with various ornaments, which often become more brilliant during the breeding-season, and which are sedulously displayed before the females.
Its numbers, however, vary considerably in different years, as in some summers I have seen Wrynecks in almost every garden, hedgerow, or thick bush in the Island; always when perched, sitting across the branches or twigs, on which they were perched, and never longways or climbing, as would be the case with a Woodpecker or Creeper; and the noise made by the birds during the breeding-season, was, in some years, incessant; this was particularly the case in the early part of the summer of 1866, when the birds were very numerous, and the noise made was so great that on one occasion I was told that the Mackerel Birds seriously interrupted a scientific game of Croquet, which was going on at Fort George, by the noise they made; I can quite believe it, as, though I was not playing in the game, I heard the birds very noisy in other parts of the Island.
We know that the faces of several species of monkeys, and large surfaces at the posterior end of the body of other species, have been denuded of hair; and this we may safely attribute to sexual selection, for these surfaces are not only vividly coloured, but sometimes, as with the male mandrill and female rhesus, much more vividly in the one sex than in the other, especially during the breeding-season.
Nor does he know of any striking difference in external structure between the sexes, excepting the prominences which become developed during the breeding-season on the front legs of the male, by which he is enabled to hold the female. Anderson, 'Proc. Zoolog. Dr.
The males of very many species do not assume their ornamental dress until they arrive at maturity, or they assume it only during the breeding-season, or the tints then become more vivid. Certain ornamental appendages become enlarged, turgid, and brightly coloured during the act of courtship.
When the sexes differ in colour or in other ornaments the males with rare exceptions are the more decorated, either permanently or temporarily during the breeding-season. They sedulously display their various ornaments, exert their voices, and perform strange antics in the presence of the females.
"No, we shall not, for they only come on shore in the breeding-season; but we will make a turtle pond somewhere which they cannot get out of, but which the sea flows into; and then when we catch them we will put them into it, and have them ready for use as we require them." "That will be a very good plan," replied William.
