_Plumages._--Like other woodpeckers, the young are hatched naked and
blind, but the juvenal plumage is acquired before the young leave the
nest. In this the young male closely resembles the adult female, but
the colors are duller, the barring is less distinct, and the white bars
are suffused with brownish white; there are indistinct dusky shaft
streaks on the chest and little or no red on the abdomen, which, if
present, is more orange or yellowish; there is no clear red on the
head, but the gray crown is sometimes suffused centrally with dark red
mixed with the gray; the hind neck is often suffused with pinkish or
yellowish. The juvenal female is similar to the young male, but the
top of the head is darker gray, or dusky, and there is less reddish
or yellowish suffusion anywhere. The juvenal plumage is apparently
worn through the first fall; I have seen it as late as December 20,
but Forbush (1927) says that it is shed between August and October. In
the first winter plumage, there is an advance toward maturity, young
males acquiring more red on the crown and occiput, and young females
on the latter. There is probably a more or less continuous molt during
winter, or a partial prenuptial molt in early spring, by which young
birds become practically indistinguishable from adults. Adults have a
complete postnuptial molt late in summer and early in fall.
_Food._--Bendire (1895) says:
Its food consists of about equal proportions of animal and
vegetable matter, and it feeds considerably on the ground.
Insects, like beetles, ants, grasshoppers, different
species of flies, and larvae are eaten by them, as well
as acorns, beechnuts, pine seeds, juniper berries, wild
grapes, blackberries, strawberries, pokeberries, palmetto
and sour-gum berries, cherries, and apples. In the South
it has acquired a liking for the sweet juice of oranges
and feeds to some extent on them; but as it always returns
to the same one, until this ceases to yield any more
juice, the damage done in this is slight. It has also been
observed drinking the sweet sap from the troughs in sugar
camps. The injury it commits by the little fruit it eats
during the season is fully atoned for by the numerous
insects and their larvae which it destroys at the same
time, and I therefore consider this handsome Woodpecker
fully worthy of protection.
