>>3619628>Are you guys going full duck hunter and using face paint and blinds?You will get better results doing that(3D ghillie suits are ultra cheap on amazon), but you will also get better results simply wearing muted colors in darker greens and browns. Bright colors, especially white are alarm coloring, so flashing around a white lens barrel or white hands or ball cap is going to put wildlife on edge.
If you want ground animals you'll need to learn tracking techniques then set up along game trails or near watering holes. For birds you'll need to look for their food crops and stake out those. With the smaller birds, familiarity around them is the best way to get them to fly closer. So, just being around the area and moving slowly is enough to warm up to you.
For skittish large birds that have generations of shyness from humans you'll need to settle in with a blind. Try to match your backdrop behind you to your clothing in relation to dark and light. All the camo in the world won't help you if you are backlit by something brightly colored so everything can instantly see you moving around.
If you drop money on a popup blind like this one, match your camo to the inside of the blind.
If you use a mirror lens you need to understand that when a mirror lens is pointed at you it acts like a bright signal mirror that instantly catches everyone's eye. Birds really don't like big eyes looking at them and that's what a mirror lens looks like. They are the worst lens you can use for skittish birds and animals. You also can't prevent that from happening with a lens hood.
