For see how she looks after their wedding garments--giving to most of
the birds a new suit, gay and gorgeous, especially to the bridegrooms,
as if fine feathers _did_ make a fine bird! Or does she do all of this
to meet the fancy of the bride, as the scientists tell us? Whether so
or not, it is a fact that among the birds it is the bridegroom who is
adorned for his wife, and sometimes the fine feathers come by a
special moult--an extra suit for him!
Take Bobolink, for instance. He has two complete moults a year, two
new suits, one of them his wedding suit. Now, as I write, I hear him
singing over the meadow--a jet-black, white, and cream-buff lover,
most strikingly adorned. His wife, down in the grass, looks as little
like him as a sparrow looks like a blackbird. But after the
breeding-season he will moult again, changing color so completely that
he and his wife and children will all look alike, all like sparrows,
and will even lose their names, flying south now under the name of
“reed-birds.”
Bobolink passes the winter in Brazil; and in the spring, just before
the long northward journey begins, he lays aside his fall traveling
clothes and puts on his gay wedding garments and starts north for his
bride. But you would hardly know he was so dressed, to look at him;
for, strangely enough, he is not black and white, but still colored
like a sparrow, as he was in the fall. _Apparently_ he is. Look at him
more closely, however, and you will find that the brownish-yellow
color is all caused by a veil of fine fringes hanging from the edges
of the feathers. The bridegroom wearing the wedding veil? Yes!
Underneath is the black and white and cream-buff suit. He starts
northward; and, by the time he reaches Massachusetts, the fringe veil
is worn off and the black and white bobolink appears. Specimens taken
after their arrival here still show traces of the brownish-yellow
veil.
Many birds do not have this early spring moult at all; and with most
of those that do, the great wing feathers are not then renewed as are
bobolink’s, but only at the annual moult after the nesting is done.
The great feathers of the wings are, as you know, the most important
feathers a bird has; and the shedding of them is so serious a matter
that Nature has come to make the change according to the habits and
needs of the birds. With most birds the body feathers begin to go
first, then the wing feathers, and last those of the tail. But the
shedding of the wing feathers is a very slow and carefully regulated
process.
In the wild geese and other water birds the wing feathers drop out
with the feathers of the body, and go so nearly together that the
birds really cannot fly. On land you could catch the birds with your
hands. But they keep near or on the water and thus escape, though
times have been when it was necessary to protect them at this season
by special laws; for bands of men would go into their nesting-marshes
and kill them with clubs by hundreds!
