Birdseye maple, one of the rarest kinds of
wood on the planet, has a distinctive pattern
that looks like tiny, swirling eyes disrupting
the smooth lines of grain. Birdseye maple isn't
a variety or species of maple, but rather a
phenomenon that occurs within several kinds of
timber due to an unknown cause. Perhaps the
valuable anomaly showcases wood's reaction to a
fungal or viral infection, genetic mutation,
bird pecking, climate change, soil conditions,
growth history, or some other mysterious
element.
Birdseye maple has a medium density and
variable color. The outer rings of the tree
create lumber that's usually a creamy, light
amber color with darker birdseye patterns. The
inner rings, called heartwood, might be deep
amber or reddish with dark brown birdseye.
Depending on the frequency of the birdseye
swirls, each 1/8" to 3/8" wide (1/3-1 cm), the
wood may be extremely valuable. Woodworkers
prize the timber because it "turns" well on a
lathe, meaning it can be shaped into decorative
canes, chair legs, or handles. After it's
finished, birdseye maple doesn't scratch easily.
Birdseye maple, occurring in Acer
saccharum, only refers to the most common
species of tree. Millers also find the
deformation in red maple, white ash, Cuban
mahogany, American beech, black walnut, and
yellow birch. These trees that grow in the Great
Lakes region of Canada and the United States
yield the heftiest supply, along with some
varieties in the Rocky Mountains. Although there
are a few clues in a tree's bark that indicate
the lumber might have birdseye, it is usually
necessary to fell the tree and cut it apart
before you know for sure.
Refined specialty products, such as the
dashboard of a Rolls Royce, are made of birdseye
maple. Since it is such a rare and unusual
lumber type, it's very expensive and in short
supply. Its cost in board feet can be hundreds
of times that of ordinary hardwood. Boxes and
bowls for jewelry, thin veneer, humidors, canes,
furniture inlays, handles, and guitars are made
from the decorative wood. These beautiful
collectors items seem to shimmer and swirl under
the curling circles of birdseye.
Being able to cultivate birdseye, or
bird's eye, in hardwood would be such a valuable
commodity that researchers and arborists
vigorously study the mysterious phenomena. So
far, they have seemed to discount several
theories, namely that pecking birds deform the
wood grain and that an infecting fungus makes it
twist. However, no one has demonstrated a
complete understanding of the combination of
climate, soil, tree variety, or insects that
reliably produces the valuable maple
I have personally found birdseye maple as
small as an inch in diameter in the woods. I
could tell because of the dark bark and bumps
protruding from the bark.
