There never was a happier or more devoted husband than the male bluebird is. But among nearly all our familiar birds the serious cares of life seem to devolve almost entirely upon the female. The male is hilarious and demonstrative, the female serious and anxious about her charge. The male is the attendant of the female, following her wherever she goes. He never leads, never directs, but only seconds and applauds. If his life is all poetry and romance, hers is all business and prose. She has no pleasure but her duty, and no duty but to look after her nest and brood. She shows no affection for the male, no pleasure in his society; she only tolerates him as a necessary evil, and, if he is killed, goes in quest of another in the most business-like manner, as you would go for the plumber or the glazier. In most cases the male is the ornamental partner in the firm, and contributes little of the working capital. There seems to be more equality of the sexes among the woodpeckers, wrens, and swallows; while the contrast is greatest, perhaps, in the bobolink family, where the courting is done in the Arab fashion, the female fleeing with all her speed and the male pursuing with equal precipitation; and were it not for the broods of young birds that appear, it would be hard to believe that the intercourse ever ripened into anything more intimate. With the bluebirds the male is useful as well as ornamental. He is the gay champion and escort of the female at all times, and while she is sitting he feeds her regularly. It is very pretty to watch them building their nest. The male is very active in hunting out a place and exploring the boxes and cavities, but seems to have no choice in the matter and is anxious only to please and encourage his mate, who has the practical turn and knows what will do and what will not. After she has suited herself he applauds her immensely, and away the two go in quest of material for the nest, the male acting as guard and flying above and in advance of the female. She brings all the material and all does the work of building, he looking on and encouraging her with gesture and song. He acts also as inspector of her work, but I fear is a very partial one. She enters the nest with her bit of dry grass or straw, and having adjusted it to her notion, withdraws and waits near by while he goes in and looks it over. On coming out he exclaims very plainly, "_Excellent! excellent!_" and away the two go again for more material.
