I see, so you generated that map of 3 counties and it was in fact not on the site for me to find.
If you were not ignorant of eBird you would have known how to generate such maps on your own, and understand the data that go into them. You don't.
I queried the database for checklists of Edmonson Co, KY. There were 449. Today there are 450. While you typing away on your computer trying to find new ways to be obtuse, someone else was in your study area not finding bigfoot.
The map I provided was a specific query into the locations of
some of those checklists, namely those that included Carolina Chickadee. The fact that my screencap of that map overlapped neighboring counties is irrelevant. I asked for just Edmonson County but it spat out all locations for checklists included Carolina Chickadee and I screencapped a window that would include those locations. So? The point was simply to illustrate the wide distribution of points.
I found the locations to be if anything even more highway location related than I had given credit for previously. So my understanding of where birders go would seem to be precise.
Then you're doing it wrong or you're being highly disingenuous about what you think you've seen. There are checklist locations on roads and trails and off roads and trails. So?
More to the point, consider the checklists entered for the hotspot at the main parking lot for Mammoth Cave National Park. Yesterday, a guy named Steve Kistler (friend of yours perhaps?) and 6 comrades birded a portion of the National Park from about 8:15–10:15 am. The location for their 2-hour jaunt is recorded as the parking lot. They must be pretty good birders (or that's a very exciting parking lot) because they reported 21 species.
A deeper dive reveals that they actually report traveling 1.5 miles in those 2 hours. Ah, now it makes sense. They must've taken a walk along a local trail but reported the location as the main location for the National Park. We do stuff like that all the time.
Check out my attached map from Douthat State Park in Virginia, a bit north of Clifton Forge. The blue line illustrates a likely route I would follow were I birding that lovely place today. There is no way I would not explore Blue Suck Hollow. But I would also write down what I found in the parking lot and I'd take a few minutes to scan the lake. When I later entered these data into eBird, I'm asked to pinpoint a location like the one I annotated on the attached map. In general it shows where I was, but it doesn't really, does it?
I never claimed to be able to see more than these folks, I claimed to be looking at different areas and different things.
I'm not saying you're ignorant of the wildlife in the area (though you are), I'm saying you're ignorant of the efforts of people in that area pursuing wildlife (and other things).
I've never claimed to have superhuman powers for noticing things as I'm obviously human. . . . Some of the simplest places to start is to stop dismissing a glimpse of movement or a stick break or an odd shape as nothing and moving along.
So your claim to noticing-stuff fame is that you were able to divine a 400kg giant from 3m away. Do you realize that we birders pick out 20g sprites from 50m away? (I'm good to about 400m if they're singing.)
