These birds seemed to have little to no fear. They were feeding on a carcus when I walked up on them. Several flew and circled around while the others stayed close to their meal.
This whole series of the Turkey Vultures flying and on the ground are VERY nice. I have a few of them but none as close up and nice as yours. I'm seeing I do need a bigger lens! The 150mm is fine for deer and geese but things that fly high or are at all small are not easy to get to.
