The Guayaquil Woodpecker is one of the relatively seldom photographed species within the Campephilus genus. Here we have a beautiful image of a female Guayaquil Woodpecker captured by Charles Cruze in Ecuador. This sex and species closely resembles the female Crimson-crested Woodpecker, but in the Guayaquil W. the white does not extend above the base of the bill the way it does in the other bird, and the entire head is red. The forecrown in female Crimson-crested W. is black.

In this brief video of a male Guayaquil Woodpecker at the Ayampe River in Ecuador, you'll observe it looking around and drumming.  This video by videoclientesm  includes a link in its description to a bird tour site called Sword Billed Expeditions.  Press play, then change the setting at the lower right of the video box from 360p to 480p to watch it at higher resolution.

Birds of Peru by Thomas S. Schulenberg describes the typical voice and drumming of this bird as follows:   

Call like that of Crimson-crested Woodpecker.  Drum is heavy, dying away at the end, 4-7 strikes.

Guayaquil & Red-necked Woodpecker Illustration

The large bird depicted in this hand-colored lithograph by Delahaye appears in Alfred Malherbe's Monographie des picidées (1859-1862).  It is a Guayaquil Woodpecker, listed here with its old name Mégapic de Sclater.  Curiously, the sex of the bird is noted as male, and that appears to be an error.  The male Guayaquil Woodpecker's head is entirely red, but for a small black and white patch below its ear.   The female Guayaquil Woodpecker possesses a white band extending from the base of its bill to its white neck stripe.

The two pairs of birds in this illustration are two subspecies of the Red-necked Woodpecker.  While most of the illustrations in this work are excellent, these do not quite capture the splendid appearance of this bird.  It must have proved very challenging to draw these relatively large birds to such a small scale!

Imperial Dreams: Tracking the Imperial Woodpecker Through the Wild Sierra Madre

Originally posted 2/10/13 - backdated to organize posts by topic. 

From Amazon.com, we have this description of Tim Gallagher's upcoming book on the Imperial Woodpecker: 

Naturalist Tim Gallagher journeys deep into the savagely beautiful Sierra Madre, home to rich wildlife and other natural treasures—and also to Mexican drug cartels—in a dangerous quest to locate the rarest bird in the world—the possibly extinct Imperial Woodpecker, the largest of all carpinteros. 

The story of his search and travels should be a most interesting read! Fortunately for us, Gallagher has launched a related blog with beautiful photos and commentary that you can visit here:

The magnificent Imperial Woodpecker is depicted in this hand-colored lithograph from French naturalist Alfred Malherbe's four-volume work, Monographie des picidées (1859-1862).  There is another illustration and more information about the work available here at this link.

The largest woodpecker in the world, the female Imperial Woodpecker is shown in full with her tongue extended, contrasted with the male whose crest is red and black.  In the background, male and female Ivory-billed Woodpeckers are depicted in what certainly appears to be an adaptation of John James Audubon's painting of the birds in 1826.

New Study Analyzes Only Known Footage of Vanished Imperial Woodpecker

Originally posted  10/26/11 - backdated to organize posts by topic.

There is big news today as the only film ever found of an Imperial Woodpecker is released in the form of 85 seconds of stunning color movie footage!  The film provides us with a unique look back through time at a species that is presumed to be extinct.

At two-feet tall, the magnificent Imperial Woodpecker of Mexico was the largest woodpecker in the world.  It probably became extinct in the late 20th century.  To date, there has been no known photo or film documentation available of this species in life.  But that changes today with the publication of a new paper in the October, 2011 issue of The Auk, the journal of the American Ornithologists' Union.

The paper, by lead author Martjan Lammertink along with four Cornell Lab of Ornithology staff members and two Mexican biologists, is entitled Film Documentation of the Probably Extinct Imperial Woodpecker (Campephilus Imperialis).   It details the remarkable 16-mm color film of an Imperial Woodpecker shot in 1956 by William L. Rhein, a dentist and amateur ornithologist.  Rhein shot the film with a hand-held camera from the back of a mule while camping in a remote location in the Sierra Madre Occidental in Durango state, Mexico.

Here is a link where you can view the 85-second color film, download the Auk article, hear Rhein narrate scenes from his 1956 expedition, read about the March 2010 follow up expedition to the film site, and see the painted Imperial Woodpecker cover art that serves as the cover of the current edition of The Auk:


Although Rhein has been widely attributed with the last sighting record of an Imperial Woodpecker, the existence of his film was not known until recently.  In the mid-1990s, biologist M. Lammertink discovered a mention of the film at Cornell in letters that Rhein and a colleague sent to ivorybill researcher James Tanner in 1962.  He tracked Rhein down and they viewed the film together in 1997.  In 2005 Rhein's nephew, R. Thorpe, donated the film to the Macaulay Library at the Cornell Lab of Ornithology.

Viewing the amazing film footage, you will see a female Imperial Woodpecker hitching up and foraging on the trunks of large Durango pines in its old-growth forest environment before launching into flight.  A March 2010 expedition to the film site gained insights on the bird's probable extinction, but turned up no evidence that Imperial Woodpeckers are still alive.  Unfortunately, the bird and its old-growth forest are gone now, making the film footage an especially precious find.

This rather large image befits the Imperial Woodpecker, the largest woodpecker in the world.  According to Wikimedia Commons, this chromolithograph appeared in The Auk in 1898, and the artist was John Livzey Ridgway (1859-1947) an American illustrator and brother of ornithologist Robert Ridgway.  Public domain image.

Imperial Woodpecker, Close Up

Originally posted  8/9/10 - backdated to organize posts by topic.

I just came across this specimen photo, a close up of a female Imperial Woodpecker head from the Museum für Naturkunde Berlin and shared with us here by Dysmorodrepanis through Wikimedia Commons.  The largest of all the woodpeckers, the bird you see here is a very old specimen, but spectacular nonetheless.  How much more spectacular would it be to see it in action, live in a pine forest in Mexico today?

Here's a link to a related article from 2003 about a search for the Imperial Woodpecker by BirdLife International that's an interesting read:

I was pleasantly surprised to find this illustration of the head and foot of an Imperial Woodpecker, accompanied by the same for the Black Woodpecker of Europe (Dryocopus martius) for comparative purposes in the preface of Alfred Malherbe's Monographie des Picidées.  The image above is within the public domain and it appears here courtesy of the Rare Book & Manuscript Library, Columbia University in the City of New York.

The Imperial Woodpecker, the largest woodpecker in the world, is the subject of an earlier post here at Campephilus Woodpeckers and, appropriately, the subject of the first plate within Monographie des Picidées:


While we're on the topic, recently Mark Michaels made the following post at the Ivory-bill Researchers Forum that will lead you to a rarely seen still from a video of the Imperial Woodpecker that belongs to Cornell University.  He wrote:

This recent publication from Partners in Flight includes a still from the footage of the Imperial Woodpecker on page 11. It should have some relevance for IBWO searchers. Another still appears in Snyder's Travails of Two Woodpeckers, but as far as I know this is the first time any of the images has appeared online.


Also, here is a link to the organization's website:  http://www.savingoursharedbirds.org/

To my knowledge, this is the sole imagery available of the Imperial Woodpecker aside from illustrations and images of museum specimens, so it's quite a wonder!

Ivory-Billed Woodpecker Specimen at Harvard

Originally posted 2/28/11 - backdated to organize posts by topic.


Ivory-Billed Woodpecker, originally uploaded by hyperion327

This impressive looking, male Ivory-billed Woodpecker specimen is on display at the Harvard Museum of Natural History in Cambridge, Massachusetts. According to the Onithology Information System (ORNIS) database, a total of 260 North American and 9 Cuban ivorybill specimens collected from March 7, 1844 to December 6, 1935 are housed in North American collections (not including any specimens that are housed in museums in Cuba). Most specimens were collected in Florida in the late 1800s to early 1900s.

The Top 5 holders of ivorybill specimens, according to ORNIS are:

Harvard, MA - 72
The Field Museum, IL - 38
The Smithsonian, DC - 35
American Museum of Natural History, NY - 27
The Academy of Natural Sciences, PA - 20

With regard to collecting any animal that has become endangered or worse, we'll probably never know how many were enough to collect, and how many were excessive.

From the ORNIS site:  

Over 5 million bird specimens are housed in North American collections, documenting the composition, distribution, ecology, and systematics of the world's estimated 10,000-16,000 bird species. Millions of additional observational records are held in diverse data sets. ORNIS addresses the urgent call for increased access to these data in an open and collaborative manner.

Ivory-billed Woodpecker: Tim Gallagher Interview, plus a Lament from the Past

Originally posted 3/30/11 - backdated to organize posts by topic.

Tim Gallagher, ornithologist and author of The Grail Bird, relates his famed sighting of an Ivory-billed Woodpecker in the Big Woods of Arkansas, seven years ago, in a brief portion of this recent podcast by CBC Radio. The interview begins about 6 mins into the podcast.

The illustration at right is from an article entitled The Passing of Birds by Eugene Strong Rolfe which appeared in The Bay State monthly (1900), now in the public domain.  Rolfe's piece contemplates extinct and endangered wildlife at a time of rampant specimen collecting in the USA stating that:  

It is with keen regret that the mind contemplates the total extirpation of types that have heretofore ministered to our necessities or pleasures.  

This interesting albeit sad read can be found starting on page 413 of the monthly (page 430 of the pdf document), available for browsing or free download at Google books. 

Ivory-billed Woodpecker Search - Project Coyote Update

Originally posted 3/18/11 - backdated to organize posts by topic.
 
In February, I spent just over a week in east-central Louisiana with a couple of good friends in our ongoing search effort (dubbed Project Coyote) for the Ivory-billed Woodpecker.  Our trip report includes several images of trees of interest and habitat, and a sound file of two possible double knocks that I heard in the field, but which are rather soft in volume on the recording.

Follow this link to find the update posted on March 17, 2011:  Project Coyote Updates

Photo taken in Singer Tract, Louisiana by Arthur A. Allen (April 1935).

Visiting Louisiana in the wintertime usually gives this New Yorker a welcomed break from the cold!  This time, the first half of the trip was frigid, with overnight temperatures in the 20s before it warmed up considerably for the rest of our days there.  I enjoyed meeting a few fellow searchers for the first time over dinner.  Of course, I always feel fortunate to spend time exploring and enjoying the wildlife and scenery of the Louisiana forests.  

On this trip, I saw dozens of armadillos roaming around the forest, rifling through the leaf litter with their long snouts looking for bugs and worms.  They got me curious, and upon returning home, I was surprised to learn that there are around 20 species of armadillos in the Americas!  The Nine-banded Armadillo you see here is the sole species that inhabits the USA.

Wikimedia Commons has posted this photo and a few others of Ivory-billed Woodpeckers at the Singer Tract in Louisiana that were taken by Arthur A. Allen of Cornell University.  This photo is accompanied with the following information at Wikimedia:

...Female Ivory-Bill returning to nest. Photo taken in Singer Tract, Louisiana by Arthur A. Allen (April 1935). From Recent observations of the Ivory-Billed Woodpecker (Auk) Volume 54, Number 2, April, 1937.
  This work is in the public domain because it was published in the United States between 1923 and 1963 with a copyright notice, and its copyright was not renewed. 


The full-text of the aforementioned article by Arthur A. Allen is easy to find (search using his name in the author field) at the Searchable Ornithological Research Archive (SORA).  The image above and several other interesting images appear in the article.  You can find it here:


Cornell offers more images of the Singer Tract in Louisiana and Ivory-billed Woodpeckers in its digital collections.  Some are in color and the images are definitely worth a look.  The entire collection of these images is not easy to retrieve with a single search, so try various keywords like ivorybill, woodpecker, and singer tract and a few searches if you want to find them.


Visit the Cornell University images here.

From past to present, Cornell shares details about a new book being written by leaders of the Cornell Lab’s Ivory-billed Woodpecker Recovery Project and partner organizations in the Autumn 2010 edition of Living Bird Magazine.

Mark Bonta of Delta State University in Cleveland, Mississippi delivers very interesting commentary on the continuing search for the Ivory-billed Woodpecker along with the Delta blues in a new podcast discussion.  Ivorybill comments begin just after 14 minutes into this podcast:

Geography of the Delta Blues and the Ivory-billed Woodpecker 

I was pleased to discover this illustration, new to me, amid an extensive collection of antique bird illustrations and bird photos.  The collection is available in a web album belonging to Avigraphicon at this link:
 
Avigraphicon's Public Gallery

Avigraphicon provides these notes on the book that this plate belongs to:

Captain Thomas Brown's illustrations following Alexander Wilson and Lucien Bonaparte's seminal text, originally published in the three-volume Jameson edition of the American Ornithology. These plates are from the later "Illustrations" volumes published between 1831 and 1835... Brown expanded the works of Wilson and Bonaparte to include 161 additional birds, and enlarged the illustrations of 87 others.

If you're at all curious to know what it's like to successfully search for, find and study the Ivory-billed Woodpecker, then you will enjoy the new book Ghost Birds: Jim Tanner and the Quest for the Ivory-billed Woodpecker, 1935–1941 by Stephen Lynn Bales.  I found it to be a truly fantastic read on so many levels.  


The author has set up a site for the book here:


And, Cyberthrush has written a nice review of the book at Ivory-bills Live.

A Pair of Ivory-billed Woodpeckers - Specimens Photo

Originally posted 10/1/10 - backdated to organize posts by topic.


ivory bills, originally uploaded by slider5.
This pair of Ivory-billed Woodpecker specimens can be found at the Fairbanks Museum in St. Johnsbury, Vermont. I've been mentioning raised crests frequently, and so I felt intrigued to see the raised crest on the male bird at right in this photo. It's something that you almost never see in ivorybill photos or specimens. I wonder what taxidermy technique was involved in raising the crest.

Many thanks to slider5 for granting permission to post this photo here.

Even more intriguing is a new report from Arkansas of a sighting of a pair of Ivory-billed Woodpeckers by Jackson Roe and his dad reported on Jackson's blog!  UPDATE: In a later post, Jackson Roe conveyed that the birds he and his dad saw were Red-headed Woodpeckers, not ivorybills.  Both types of woodpeckers have white patches on their backs.  Their search continues.


Let's all wish them the very best of luck in their future efforts to further document living ivorybills!
