I returned to the Choctawhatchee basin in the Florida panhandle in February, with the Cincinnati group lead by John Ruthven. The last time I had been there was 2010, when we froze in the swamps, sometimes breaking ice as we launched our kayaks. I missed last year’s expedition as it conflicted with my term as Artist in Residence at Everglades National Park. This year, the mild winter spared us the frozen mornings of the last trip. We had near perfect conditions, although the water was about 6 feet lower than during my last visit. This limited boating to stream channels, as the swamps were nearly dry. This enabled us to hike further than we had on other trips, and we found some promising habitat for Ivory-Bills.
We had no sightings and heard no double knocks, but we did find some trees with tantalizing evidence of large woodpeckers foraging. Ivory-Bills like to use their beaks as chisels to pry off bark from recently dead young hardwoods. The tip of the beak is even flattened like a chisel, and we hear it leaves a mark like someone used a screwdriver to pry the bark off. Pileated woodpeckers can also leave similar horizontal marks, but they aren’t supposed to have the same sharp-edged grooves that Ivory-Bills leave.
One area in particular had a tree with some very hard-edged grooves, and the general habitat matched the description given to us by old timers in the area who claim to have seen the bird several times over their lifetime. They tell us, “You boys are spending too much time down in those river swamps.” Of course, we’ve had some success in river swamps…. myself and another in our group, Sally Woliver, had a good sighting in 2008 of a male Ivory-Bill along Bruce Creek, and Geoff Hill’s gang has made several sightings in the Choctawhatchee basin, mostly along stream channels. What the locals have told us, though, is that the IBW’s prefer upland swampy valleys surrounded by hardwoods. The spot where we found this tree fit that description. On Google Earth, you can see a horseshoe-shaped cypress/gum swamp, with mature hardwoods all around. We walked out on an old logging road through the hardwoods until we encountered the swamp forest, and found several trees within a 100 square yard area that had been worked on by possible Ivory-Bills. Unfortunately, we found this place on the last day, so a more detailed investigation and “stake out” will have to wait until next time.
Here are a few sights from the trip to the Choctawhatchee River basin:
