Life histories of North American woodpeckers

Perhaps a downy woodpecker does not really work any harder
or faster for its food than any other bird, but somehow it
seems that it does. I found one once on an inclined limb of
a catalpa near the Highland Pines Inn and watched it work
up ten feet in thirteen minutes. During that time downy’s
blows fell good and hard at the average of a hundred
strokes each minute except for a dozen momentary stops when
a big bird flew over, or the downy scratched its head. It
was feeding on small white grubs which it secured at an
average rate of four per minute. * * *
These woodpeckers have the habit in the Sandhills of
digging holes in which to sleep. One found a suitable
place in the end of a dead limb of a large gum standing in
a flooded swamp near Mid Pines Club. This limb had been
broken and left a stub sticking out about five feet long
at right angles to the trunk of the gum and about forty
feet above the ground. It was about five inches in diameter
where the woodpecker began work on it. Work was started
on the under side of the limb about nine inches from the
outer end on February 11, 1927, and the bird dug at it for
forty-five minutes to such good purpose that the hole would
then admit all its bill and half its head. As it worked
it clung head down under the limb. Then it left its work
to go foraging but came back in thirty minutes to resume
work. During the next three days this woodpecker must have
worked steadily for it then had a hole into which it could
completely disappear. But the hole was not large enough nor
deep enough, and the bird was still at work, continually
popping in and out (backward) of its hole; usually when it
backed out it carried a bill full of chips and shavings
that it threw over its shoulder. As it did so, it glanced
once or twice to either side as if to assure itself that
all was well. Then back into the hole for another period
of steady hammering. Apparently this woodpecker worked
thus from thirty minutes to an hour after each half hour’s
foraging trip. Two more days of work completed the sleeping
quarters in a snug cozy retreat. When finished, the hole
was six inches deep, and the limb around it was a mere
shell. The opening being beneath the limb, it was sheltered
from storms, and from any water running into it.
