    Ivorybill Searcher's Forum: Insights and current reports

    What are folks wearing for camo? I find even when videotaping common birds that a face mask has a remarkable effect. Often get more of a curious reaction than alarm even when in close. When I was in the Cache NWR I had a mink walk up within 10 feet, stop, and look right at me. I could see...

    If you have longer optics or a higher resolution sensor it is essentially equivalent to reducing the distance between you and the bird. With the addition of a 2x multiplier to the front of your camcorder you would get 4x the number of bird pixels at the same distance from the bird, or you would...

    Most song birds (e.g., Northern Cardinal) learn their songs which account for regional dialects. I'm guessing woodpecker calls are not learned but correct me if I am wrong. BTW: "The Singing Life of Birds" by Donald Kroodsma is a great book to read if you are generally interested in this...

    I asked a simple answer, but didn't get a simple answer (i.e. no), so I assume that the answer must be a yes, or a complicated no. Any encounter details you are willing to divulge? Or are you waiting until you have a decent image or set of images? I can wait. the veeb

    Looking at this post and what I remember of Tim's descriptions/clues I'm guessing that you might be his "informant." Are you? Any descriptions of what you saw that you can provide if you are (don't need to know where your encounters were though I'm guessing WEST of the Choctawhatchee.) Just...

    Keep in mind that "IBWO doesn't like people" so increased and more visible effort may not result in better results. Or at least that's what could be argued if results don't materialize. But the questions should be asked. Hopefully searchers will produce the goods this season wherever they are...

    I mentioned earlier that a fixed 300mm or 400mm is the way to go for flight. Having a little weight and length actually make it easier to get on and stay on a bird in flight. Here's a brief discussion on the topic from a professional bird photographer who uses Canon equipment...

    Ivory-billed Woodpecker (formerly updates)

    I'm sorry but I find this comment a bit lame and insensitive. Come on people, how about using a dSLR camera with a 300mm or 400mm lens? That's what I used when I was in the Cache. A dSLR has the advantage of having line-of-sight optics which means that if you fix your gaze on the bird in...

    If they can be observed they can be photographed. I hope that the people involved will contact talented bird photographers/videographers and put this to bed if it is real. Get people with skill and extensive field experience at photographing birds in flight or perched at a distance and get some...

    From "The Grail Bird": "I'm sure it landed on a tree trunk about fifty feet away, because I lost it for about three seconds, then I had it again, moving in a straight line through the woods, going up the bayou for another 50 feet or 60 feet, then landing again. It must have hitched around the...

    The questions as posed refer only to objective evidence such as photos or video that can be independently assessed. The rating (and I'm not taking this all that seriously) is based on where the prevailing arguments after a prolonged discussion end up. The Luneau video of the bird launching and...

    A few thoughts in anticipation of new evidence being presented. Having a stellar publication record and having a stellar field identification record are 2 different things. I'm not saying that the publication record doesn't hold any weight, but I would look at what the publications are. Just...

    As requested I have reposted my previous post from this discussion to the discussion/debate thread. Mike, maybe you can comment there on the main point of that post which was the image processing steps that I took to simulate low-res video and the shape distortion that added to a known image...

    I was asked to move this discussion of the merits of comparing fishcrow video head shapes from low res video from the IBWO evidence thread. It [may be] a little jarring if you [weren't] following it before... I never said that you can not enlarge an image, I said you need to be careful...

    I never said that you can not enlarge an image, I said you need to be careful interpreting the detail that is produced when you enlarge a low-resolution image. My point in posting: http://www.virtualbirder.com/fishcrow/perched.gif was to demonstrate with a zoomed view what was actually...

    I don't ignore evidence, I just don't see the conclusive evidence that you are claiming. Mike are these essentially the source pixels that you are claiming are a perfect match for your ibwo head and reveal a dorsal stripe? http://www.virtualbirder.com/fishcrow/perched.gif I'm sorry...

    You're right Mike. The pixels in the large black feature(s) are highly correlated, highly correlated with the pixels associated with the other foreground objects. There are all sorts of out of focus objects that appear and disappear in the foreground, just scrub the video, there's a whole...

    My casual thinking on the scale of "IBWO photos and videos" was that an ongoing "debate" would be along the lines of "Is is an IBWO? Or is it ______?" The IBWO question was implicit in all levels. IBWO has been considered by most to be "likely extinct" for decades. The most probable outcome...

    Here's a thought based on some of these ongoing debates that may never be fully resolved. I think you can generally rate the quality of an IBWO photo or video based on the types of questions that are debated on an ongoing basis. In decreasing order of quality: 5. Is it an elaborate hoax? 4...

    I'd have to agree with Mike Johnston that the extent of white does appear wrong, seems to come up too far on the wing. I don't like the fact that it is on this rather small horizontal branch with a lot of clutter. I'd like to see the feet since those would be harder to "hoax", but the clutter...

    No, as I said earlier, I suspect that the black blob is an artifact of the video capture process/back lighting and once the lighting or branch alignment changes as the blob moves in front of the tree it appears to disappear. It's elements are branches so it blends in with the trunk. I don't...

    The 11.5 minutes is really irrelevant to the current 24 frames. Just scrub the movie back and forth and look at how the cores of the black blobs are moving in synch with the rest of the foreground lattice. Not a coincidence. Let's see what other people think. Otherwise I really don't have...

    Ivorybill Searcher's Forum: Insights and current reports

    I hadn't actually played much with the movie as a movie. If you scrub it back & forth particularly toward the end of the sequence you can see that there is quite a lattice of thinner branches intersecting through the "open area" in the interior of the frame. Really looks like blobs are...
