Generally, she is more
vigilant in caring for the young, and manifests the most concern when
danger threatens. Hour after hour I have seen the mother of a brood of
blue grosbeaks pass from the nearest meadow to the tree that held her
nest, with a cricket or grasshopper in her bill, while her
better-dressed half was singing serenely on a distant tree or pursuing
his pleasure amid the branches.
Yet among the majority of our song-birds the male is most conspicuous
both by his color and manners and by his song, and is to that extent a
shield to the female. It is thought that the female is humbler clad
for her better concealment during incubation. But this is not
satisfactory, as in some cases she is relieved from time to time by
the male. In the case of the domestic dove, for instance, promptly at
midday the cock is found upon the nest. I should say that the dull or
neutral tints of the female were a provision of nature for her greater
safety at all times, as her life is far more precious to the species
than that of the male. The indispensable office of the male reduces
itself to little more than a moment of time, while that of his mate
extends over days and weeks, if not months.
