Life histories of North American woodpeckers

I have found it very difficult to decide as to the
propriety of separating a form of this species from central
and southern Florida, but after having several times laid
out and carefully compared the entire series of specimens
from more southern localities, have come to the conclusion
that to do so will, apparently, best express the facts of
the case. Going by size alone, there is little difference
between specimens from southern and central Florida
and those from localities as far northward as Maryland
(lowlands), southern Illinois, and Missouri; in fact some
of these more northern specimens are quite as small as
Florida ones. But the series from central and southern
Florida are uniformly decidedly blacker than the rest. * * *
I have restricted the name _pileatus_ to an intermediate
form, characterized by the small size of _P. p. floridanus_
combined with an appreciably lighter (more slaty or sooty)
coloration, often approaching closely the lightness of hue
of _P. p. abieticola_.
Bangs (1898), in separating the northern race from the southern, says
that “southern South Carolina must be considered the type locality
of the species, and birds from this region are as extreme of the
southern race as those from Florida.” Furthermore, Arthur H. Howell
(1932) observes that “careful study of a large series from Florida
in comparison with a series of typical _pileatus_ from the Middle
States shows no constant difference in color, as claimed by Ridgway
for the subspecies ‘_floridanus_’; evidently specimens kept for some
years become more brownish (less sooty), which fact probably explains
Ridgway’s mistake, he having compared fresh Florida skins with older
skins from the Middle States.” Probably, also, if specimens from the
two regions in similar seasonal plumage were compared, there would
not be so much difference in coloration as Ridgway claims. Even if
Ridgway is correct in his diagnosis, it would seem unwise, in the
author’s opinion, to recognize the Florida race and thus establish an
intermediate race, where the gradation in both size and color warrants
the naming of only the two extremes.
Mr. Howell (1932) says of its haunts: “The pileated woodpecker in
Florida inhabits several different types of country--pine woods,
cypress swamps, hardwood swamps, and hammocks of cabbage palmetto and
other trees. The birds are perhaps most numerous in hammocks or swamps,
where there is an abundance of decaying trees.”
