Acorn
woodpecker Melanerpes formicivorus
When
I visited A friend's house, I noticed a wonderfully designed
stencil on the top of all their exterior walls. Thank goodness I
looked a little closer before I complemented them. THEY WERE
WOODPECKER HOLES!
Range
of the Acorn woodpecker
The
Acorn woodpecker is found in the western half of Oregon and
California, and in Arizona, New Mexico and down throughout
Mexico.
Diet
of the Acorn woodpecker
The
Acorn woodpecker needs a large family to collect and store enough
acorns for the winter. Acorn woodpeckers do not feed exclusively
on acorns.
They also eat fruits, seeds, oak catkins, and insects. They can
often be seen fly-catching. They also enjoy eating poison oak
berries, (as do many other bird species). So, think twice before
removing poison oak from your yard.
Migratory
status of the Acorn woodpecker
The
Acorn woodpecker does not migrate. The family must stay near its
granary tree. However, it will move upslope in the fall
Habitat
of the Acorn woodpecker
The
Acorn woodpecker prefers areas with more than one species of oak.
So that if one species has a bad year, they will have another
source of food. They also prefer older forests and trees as these
usually produce more acorns and contain more dead wood which they
use for acorn storage and nest cavity. They also like to use
pines as the wood is softer and the bark is thick and soft and
can easily hold a lot of acorns.

Reproduction
of the Acorn woodpecker
Only
one or two pairs of Acorn woodpeckers in the group mate each
year. The rest in the group help in incubation and feeding. It
takes a village to raise a baby woodpecker?
The
Acorn woodpecker nests in a cavity that they excavate themselves,
usually in an old dead branch (snag) of pine or oak.
Niche
filled by the Acorn woodpecker
The
acorn woodpecker stores its acorns in a granary tree. This is
usually a dead tree or a large old live tree with very thick
bark. The Acorn woodpecker prefers to use pine
trees for granaries and for nest cavities, as its wood is
quite a bit softer than Oak. Do not be too worried about the
survival of your Oaks and Pines. The acorn woodpecker usually
only pokes holes through the bark. And they prefer trees that are
already dead.
How
to attract the acorn woodpecker to your garden
You
can't just have one acorn woodpecker. You have to take him, or
her, with his whole family. The acorn woodpecker lives in small
gregarious flocks.
Large
mature oaks seem to be the acorn woodpeckers favorite plant.
However, they also like pines. To learn more about Oaks check out
our Oak
pages.
Placing
a watering dish in your garden will also help to attract Acorn
woodpeckers. They like to get water from puddles or baths
rather
then from their diet (berries fruit etc.) If you have cats then a
bath (preferably a tall one) is more appropriate.
