He says--

"The whole phenomena of so-called male superiority bears a
certain stamp of spuriousness and sham. It is to natural history
what chivalry was to human history; ... a sort of make-believe,
play, or sport of nature of an airy unsubstantial character. The
male side of nature shot up and blossomed out in an unnatural,
fantastic way, cutting loose from the real business of life, and
attracting a share of attention wholly disproportionate to its
real importance."[87]

This may, I think, be regarded as a picturesque over-statement of what
is in the main true. Male efflorescence has drawn upon itself an
excessive importance, through what we may call its dramatic insistence
upon our notice. It is plain, too, that the more we examine the
question the more we are forced to the one conclusion. It is certainly
very suggestive, as Professor Ward points out, that those mammals and
birds in which the process of male differentiation has gone farthest,
such as lions, buffaloes, stags and sheep among mammals, and peacocks,
pheasants, turkey-cocks and barn-door-cocks among birds, do
practically nothing for their families. Among the gallinaceae it is the
female who undertakes the whole burden of incubation, and feeding and
caring for the young; during this time the male is running after
adventures, in some cases he returns when his offspring are old
enough to follow him and form a docile band under his government.[88]
The conduct of the male turkey is much worse, and he often devours the
eggs, which have to be hidden by the mother, while later the offspring
are only saved from his attacks by large numbers of females and the
young uniting in troops led by the mothers.[89] The polygamous
families of monkeys are always subject to patriarchal rule. The father
is the tyrant of the band--an egoist. Any protection he affords to the
family is in his own interest, frequently he expels the young males as
soon as they are old enough to give him trouble, the daughters, in
some cases, he adds to his harem; only when old age has rendered him
powerless are the tables turned, and the young, for so long oppressed,
rebel and sometimes assassinate their tyrannous father. There is very
little evidence of paternal affection among mammals. Even among
monogamous species, where the male keeps with the female, he does so
more as chief than as father. At times he is much inclined to commit
infanticides a
