We have all seen the dreaded sight of buzzards circling above the calving pasture. This should cause alarm, especially with the increased presence of the black headed buzzards (technically called the black vulture).
Thanks to the help of the University of Kentucky Department of Forestry and Natural Resources, we were able to try out one of the black vulture effigies (a replica of a dead black vulture). Vultures have a strong sense of mortality and if they see one of their own dead somewhere, they tend to leave that area alone so that they too don't have the same fate.
Vultures, as with all other wildlife, will take advantage of resources available to them, and unfortunately this behavior sometimes involves human dwellings or livestock operations. Fortunately, vultures respond well to relatively simple methods that discourage them from congregating or feeding in critical areas.
