Brief Update: Some Thoughts, Future Posts, and Some Imagery Just for FunPosted: June 27, 2018
While I have not been keeping close track of numbers, I’m going to give some guesstimates on trail cam results. Our current settings (~12 hours daily at 20 second intervals) result in ~2000 captures per day with cards filling and beginning to overwrite at somewhere between 80-90 days. PlotWatcher’s proprietary software makes the process a lot easier than it was with the old Reconyx images, which had to be stepped through manually. This is the first time I’ve really immersed myself in reviewing imagery, and even with the ability to review the images in a video format, it’s a tedious process involving a lot of stops and starts.
I’d estimate that I’ve reviewed about 500,000 images over the past 8 weeks, and I’m struck by the relatively small number of hits, especially avian ones. Squirrels make up a significant percentage, probably more than half, the total captures, and I suspect that Northern Cardinals are second. Other common species show up infrequently. I don’t recall seeing any identifiable Blue Jays (although there may be one among the images below). Nor were any Wild Turkeys captured (including on a camera that was mis-aimed, with the target tree at the right edge of the frame and a large open area to the left as shown in some of the captures below).
Woodpecker captures have been extremely rare, except on the targeted hickory discussed post before last, that was already extensively scaled. Among the rest of the images I’ve reviewed thus far, I’ve seen three identifiable Pileated Woodpeckers – one on a target tree (below) and the other two on an adjacent tree that had one pre-existing PIWO foraging pit in the frame – and as best as I can recall, a couple of identifiable Red-bellied Woodpeckers and a Hairy (captures not saved/posted).
I suspect it would be fairly easy to obtain Pileated imagery in quantity by targeting trees with obvious PIWO foraging sign, but otherwise, it seems even this abundant species is hard to capture in a camera trap. This should help illustrate another reason I don’t think the so-called failure to obtain conclusive ivorybill imagery using trail cams is very meaningful.
Assuming the ivorybill persists, it is a very rare species with incompletely understood behavior, and no one alive today, myself included, knows exactly what makes a good target tree. The best anyone can do is make educated guesses and hope to get lucky, against extremely long odds.
Now some housekeeping: the next couple of posts will be about evidence. I’ve never assembled all of Project Coyote’s evidence in a single post and discussed it as I plan to in the next post, which I expect to take live sometime next week. Look for a more theoretical piece on evidence to follow that. Both of those posts will be password protected for review, though I will try and make them public as soon as possible. After that (probably in August), I’m planning a postscript to the habitat and historic range series.
I won’t be doing regular updates on the trail cam imagery unless there’s something significant to report or I have insights similar to those expressed here.
And now some imagery. It should be illustrative of some of the challenges. See what you can find, including in the featured image . . .
