The Search for Giant Woodpeckers

Tanner IBW

Are folks still interested in the search for the world’s biggest woodpeckers, the Ivory-billed and the Imperial Woodpeckers?

According to reports being published on September 26, 2006, and summarized in the Mobile, Alabama Press-Register, a haven for ivory-billed woodpeckers has been discovered in Florida.

Auburn University researchers published evidence today of what some are describing as an ivory-bill woodpecker “Shangri-La” in the Florida Panhandle, a couple of hours east of Mobile.

Researchers said they’ve had 13 sightings of the ivory bill, long thought to be extinct, and have recorded some 300 distinctive calls and sounds associated with the giant woodpecker, the largest in the United States and a virtual Holy Grail for many birders.

In a paper to be published today in the online journal Avian Conservation & Ecology, the researchers also will provide evidence of some 20 roost cavities in the Choctawhatchee River basin north of Panama City, Fla., and distinctive foraging techniques they believe to be unique to ivory bills.

There is no photographic evidence, though.

“We’ve got bad video,” the Auburn team’s lead researcher, Geoff Hill, said of footage his team shot in Florida. “We decided bad video is worse than no video, and it distracts from what is our good evidence.”

And later….

Instead of photographs, Hill and the Auburn team have assembled other lines of evidence — audio recordings of about 200 calls with a distinctive sound, often described as a “kent,” and 100 double raps; roost cavities that Hill said are much larger than cavities made by other Southern birds he’s analyzed; and an unusual pattern of bark removal, which Hill and his colleagues believe is most likely produced by the ivory bill’s large beak and powerful chiseling.

Imperial Woodpecker

Still I wonder, are people even interested any longer? I once asked here, “Could 2006 be the Year of the Imperial Woodpecker?”. In that earlier mostly ignored blog, I pondered the new Mexican sightings. But only a few people seemed to care. Are the discoveries of “extinct” woodpeckers yesterday’s news?
