I built a perch out of a wooden dowl rod. I added a fake mouse onto the perch for visual enticement. I also have a distressed bird caller that plays 24/7 that gets their attention. The caller is called a trap bait caller. It is made by a company called lucky duck and will play 24/7 for about three weeks on four AAA batteries. The caller sells for about $18-$20. I strap the perch to the tree with the camera mounted pretty much level with the perch. When it works, it can make for some awesome pics. Here's a better picture with more of the perch in view.How do you get the pictures of the owls?
My last try at this I set up a camera on camera stake on a beaver dam to watch the beavers work. Came back to check it and the beavers had used it in the dam somewhere... never to be seen again. There probably are some good pictures on that one. Bad choice of camera mounts, who knew?
