"World’s
Largest Woodpecker"

When we think “woodpecker,” many think of a bird banging
its bill against a tree or a telephone pole. Or perhaps we recall the
good ole “Woody Woodpecker Cartoon.” However, few think
of the King of Woodpeckers: The Imperial Woodpecker.
What makes this bird so special? For starters,
at 60 centimeters (23.6 inches) in length, it is the largest woodpecker
in the world. The male displays a brilliant red, pointed crest on an
otherwise black head. The body plumage of this magnificent bird is a
stunning black and white. The female, while lacking the brilliant red
crest, is equally stunning in her black and white plumage, having a
long, curling black crest. Not only are they beautiful, but their physical
make up is just as impressive.
They have a strong ivory colored bill, a very
thick skull, and between the bill and the skull is a pad of spongy connective
tissue that acts as a cushion. They also have “yoked” feet,
with two toes pointing forward, and two backward, with sharp, strong
claws. Although the feet are adapted for clinging to a vertical surface,
they are also used for grasping and perching. The tail is stiffened,
with the shafts of the feathers terminating in hard spines, which the
birds press against a vertical surface to help support, their weight.
It also has another very special piece of equipment to help them, a
long, elastic tongue that can easily get around curves. The tongue has
a sticky glue-like substance on the end, to get the ants that are scurrying
around in their tunnels.
Unlike most other birds, woodpeckers like to
eat ants. Once found throughout the huge Sierra Madre Occidental in
Mexico, including Jalisco, their numbers have been steadily declining,
with no confirmed sightings in recent years. So, do not rush out with
your binoculars in hopes to catch a glimpse of one. The imperial woodpecker
will be listed in the 2004 IUCN Red List of endangered species under
the new classification of “Critically Endangered Possibly Extinct.”
(New tag assigned to some Critically Endangered species by Birdlife
International to indicate those species which are likely to be extinct,
but for which there is a small chance that they may still exist.)
A joint expedition by Bird Life International
and a local Mexican conservation organization, Prosima, spent 16 days
in an isolated part of Durango state, where there was an unconfirmed
sighting in a pristine canyon in 1996. The site researchers explored
was close to an area where two years before, researchers had found some
evidence of the species; unfortunately, they were unable to confirm
any sightings.
On July 11, 2003 Birdlife International researchers
ex-pressed their fear that the stunning Imperial Woodpecker, may now
be extinct after the expedition to the last area reporting sightings
of the bird, failed to find evidence of a resident population.
The bird’s decline is due to the loss
of habitat requiring an extensive area (26 km2 per pair) of continuous
open and untouched pine forest with dead trees for feeding and nesting.
Although large areas of pine forests still remain in the Sierra Madre
Occidental, they are being logged, the dead trees along with their associated
insects removed. Hunting is also thought to have contributed to the
bird’s downfall.
Is there still a glimmer of hope? Could this
bird still exist? Let’s hope so. For, the world will be a poorer
place without this magnificent bird—the Imperial Woodpecker.
