@Hal4son In the original post in this thread, post #1, you can see a really good view of what I call the Rail.
The Rail, in this OP, has a dead plinked Rat stuck behind a wire grid. That wire grid was used in an attempt to keep our Coyotes away from a bait that I was trying at that time (mid-July),... real Bacon bits. I had intended to have the Rats to be able to get behind the grid, and get to the bacon, but keep the Coyotes away from it. That Rat was a really fat one, and was able to fit behind the grid.
Where the dead Rat is imaged is what I call the Rail. It is the top of my backstop baseboards, which are a pair of 4x4 pressure-treated landscape timbers. The whole backstop is scraps and remnants, please bear with,....
The top of those baseboards, I call the Rail. It is probably 3" (2.5"+) of unobstructed pathway from their hiding area, and they have to enter the front side of the backstop, which is where numerous rodents have perished over the years (hundreds of rodents).
Dead rat, on the Rail:
And, this is a rat-size target that I made from a rolled up gym sock, and blue tape. It is true to Rat size, and it fits exactly on the Rail.
Over the Rail are a couple fence boards that make the backstop a bit taller at 18". Where the fence boards came together is a seam, I placed another fence board over them to close the seam between fence boards, to create a double thickness backstop (the rear side has extra layers as well).
construction briefly explained,.... [/ done]
The blue tape Rat target fits directly under the second fence board layer. That slightly higher extra fence board layer is where I placed the reflective tape, with the arrow points at the lowest level of the second layer board.
These is also a 'roof" board over the bait. We have Owls here, and, I gave them a cover to come out under, and make them selves more comfortable. That "roof" is the lighter colored, oxidized board. The reflective tape is attached to the red brown board behind it.
The Rat-Mouse-Thing target was very useful to me in figuring out the weird LED light shadows that made the rodents appear larger.
And it captures pellets, and keeps the backstop from loudly popping during early-on night time ranging.
To the question of daylight pics,.... forthcoming.
I found this question last night after dark. So, I'll head out when the sun comes up, and will take a daylight pic.
