Henry Windmill Ranch · Montezuma County, Colorado

The Windmill Eye

Real deer, real elk, no answer key. You call it, then Claude's call comes out of the envelope and you get to tell him why he's wrong. Nobody is grading anybody — we are building the eye the ranch cameras will use, one argument at a time.

Tell him why he's wrong

Every disagreement lands here. This is the list John and Claude actually work from — a correction, a rule of thumb, or a feature nobody had thought of yet.

The rule that makes this worth playing

Claude wrote a call for every one of these animals — a number, an age, a weight, and a paragraph of reasoning — before this page was published and before anyone saw it. Those calls are sealed into the page and they do not move. He is not scoring you against a key he already holds, because there is no key: these are photographs of wild animals nobody put a tape on.

So the comparison is honest in both directions. You are both guessing from the same picture. The only thing either of you can be measured against is what everyone else says — and when a group of people who have spent their lives looking at these animals all land in the same place, that is the ground truth, and Claude's distance from it is his error, not yours.

What each question is for

What happens to your answers

Right now they are kept in your own browser, so your board is yours. When the ranch backend goes in, every call joins one shared board and nothing you have done in the meantime is lost. The disagreements go on the list John and Claude work from. Nothing here is connected to a camera, a licence, or a season. It is a calibration exercise and nothing else.

The photographs are free-to-use reference images of wild mule deer and elk, collected for this exercise. Anything carrying a photographer's watermark was left out, along with the harvest pictures — wrong tone for what this is.
