On June 16, 1923, while collecting near Imnaha, Wallowa
County, Oregon, I frightened a Lewis woodpecker from the
top of a fence post where it was evidently having a feast.
On top of the post it had left a fresh egg, probably its
own; for it was absolutely fresh, of the right size, and
unmarked. The shell had been broken into, but the contents
not yet extracted.
In a knothole on the side of the post was an eggshell (of
the same kind), and a snail shell which had been broken
into. Wedged into the cracks of the post were several
insects (some of them still alive) of the two species
commonly known as “salmon flies” and “trout flies.” On the
ground at the foot of the post were several snail shells,
a green prune (picked into), and several cherry seeds with
stems attached.
Johnson A. Neff (1928) has much to say about the economic status of
this woodpecker, mainly in Oregon. A few quotations from his paper will
serve to show the vast amount of damage to the fruit grower that it
does in sections where it is abundant, mainly in summer and fall. He
says that Prof. Beal (1911) “mentions one case in Washington wherein
the birds tore the paper at the corners of packed boxes of apples left
in the orchard over night, picking into every apple within reach, and
necessitating the repacking of every box attacked.”
S. D. Hill wrote to Mr. Neff:
In some sections and seasons they will destroy carloads of
fruit, especially in orchards near timber. I have known
them to do 50 percent damage to a pear crop in the Peyton
district on upper Rogue River. Jackson Gyger, Ashland,
wrote: “In 1924 the loss on Spitz and Delicious apples was
about 75 percent, on Newtowns about 15 percent; Bosc and
Anjou pears about 10 percent. The loss on trees near oak
timber was nearly 100 percent. This season (1925) due to
hunting them every day the loss was possibly 50 percent
less. I bought $18.00 worth of ammunition to combat them
this year. One man can not keep them out of a seven acre
orchard, as they will work on one end while you are scaring
them out of the other.”
Mr. Neff goes on to say:
These complaints can not be over-looked, for stomach
analyses show only the volume of fruit eaten, not the
percentage of fruit damaged per tree, nor the real loss to
the orchardist. * * *
In Oregon, although it sometimes becomes a nuisance in the
small fruit plantings of various areas, it centers its
destructive activities in the Rogue Valley; there it flocks
in the greatest abundance. * * *
