I do remember quite well the running joke about the good old blue bucket…
But my question now goes to the serious side of things.
I’ve been hearing about guys using blue PVC or blue objects as attractions for coyotes…supposedly they can see blue pretty well.

Is anyone here using this technique? Can anyone tell the difference if it’s really true?
Been thinking about trying a few after Christmas.

Blue is harder for other people to see. That would be the only reason I can think of to use blue for yotes.

My opinion is you catch coyotes by their nose not there eyes. Eye appeal is a tricky thing with coyotes, it can cause refusals as easy as attraction. The guy that made pvc popular with coyote trapping has made the point many times he puts the pvc in enough cover the pipe itself cant be seen. There a reason for that. Again my opinion is there's a time and place for eye appeal but I think its a smaller piece of the pie than several other things.
If its just about getting them to see it, hang some sort of flagging above your set they can see movement better than anything.

Apparently blue stands out really well to animals that see in black and white
I heard it explained once, but can't remember the reasoning. That's why you don't want to wear light colored blue jeans while hunting.
I suppose a blue bucket/pipe sticks out well for a coyote; add a little lure and so much the better.

Maybe it’s because they see in the blue/green spectrum.
