Thanks for the kind comments!
Wadge1, Getting close to these guys just takes patience. I find approaching them rarely works for me. My best shots come from spending a few minuets with a pair of binoculars observing the trees and brush ahead along the trail. There's usually something flowering, ripening or seeding that's attracting them. I'll then position myself close to the attraction preferably next or behind some cover and remain very still. I never wear bright colors and prefer hunting garb to help blend in. You may scare them away at first but they usually return. It helps to have your cameraon a tripod or monopod so its in position when they arrive and you're not scareing them lifting the camera into position.
Hope this helps!
