Recently ran across this guy's videos on traps and trapping. Was intrigued by his description of how to create a "fast food" restaurant to attract coons and such to his trap setups. It occurs to me that many of us inadvertently do the same thing with our birds. We serve them up, fast food style! Look at his diagrams of a sterile lot vs. one that is baited and setup to attract varmints. Do we do the same thing? If not the birds, we do things with feed and such that inadvertently attract rats and mice, which then attract predators that follow them. Things like weasels, coyotes, foxes, skunks (said to be great mousers), snakes, owls, hawks, etc. They arrive in pursuit of the rats and mice, but are opportunistic and easily make the transition to our chicks and birds. BTW, if you are dealing with coons and want to trap them (I have them but don't trap if I can avoid it), he gives some pretty good tutorials on where and how to set them. Also note, if you have dogs and cats around, you have to be careful which of the "dog proof" traps you use. The double action push pull triggers can catch a dog's tongue if you use the type of bait that would attract them. These dog proof traps are probably much more effective than a live trap, for what that is worth. And about 1/3rd to 1/4th the price.
