Life histories of North American woodpeckers

Birds -- North America; Woodpeckers -- North America
Of two nests discovered by Hoyt (1905) in Claremont County, Fla., one
was 58 feet up in a live cypress about 20 yards from a nest discovered
in 1904 by the Brown brothers; the second nest built by the same pair
after the first eggs had been taken was in a cypress stub about 70
yards distant from the first and 47 feet from the ground. The opening
of the first nest was 6¾ inches by 3¼ inches, with the trunk of the
tree 15 inches in diameter at the nest cavity, which was 14 inches
deep. The second nest hole measured 6 by 3¾ inches and was likewise 14
inches deep. “The opening in both nests was uneven and rough, and just
inside the hollow was much enlarged, being 9 inches across, and unlike
the nests of other woodpeckers, was smaller at the bottom than at the
top. * * * One marked feature of the nest tree of which I have seen no
mention made is that the outer bark of those I have examined was torn
to shreds from a point some distance below the nest site to 15 or 20
feet above it. This made the nest tree noticeable for quite a distance.
The last nest taken this season had little of this work done.”
Allen and Kellogg (1937) say further:
According to McIlhenny (Bendire, 1895) the female does all
the work of excavation, requiring from eight to fourteen
days, while the male sits around and chips the bark from
neighboring trees. Audubon, however, states that “both
birds work most assiduously at this excavation, one waiting
outside to encourage the other.” Maurice Thompson (1896)
likewise reports that both birds work at the excavation. We
had no opportunity to check either statement but certainly
both birds take part in incubation and feeding the young.
The chips are not removed from the vicinity of the nest
for each one that we have examined has had piles of chips
directly below the opening though, since most of the trees
were standing in water, the chips were not very conspicuous.
